+# How to Build and Develop Voltha
+
+There are many ways to build and develop Voltha:
+
+* Use the provided Vagrant environment. This mode is by far the most reliable, and the only one officially supported.
+* Use your native MAC OS or Linux environments. These are not supported, although we provide guidance in a best effort manner and contributions/patches are graciously accepted from the community.
+
+## Build and Develop on the Vagrant Box
+
+### Prerequisites
+
+* Git client
+* Working installation of Vagrant  -- see [https://www.vagrantup.com/downloads.html](https://www.vagrantup.com/downloads.html)
+* jq -- a useful command line too to work with JSON data. On the MAC, you can install jq with ```brew install jq```; on Ubuntu you can do it with ```sudo apt-get install jq```. You will not regret it.
+
+
+### Build
+
+```
+git clone git@bitbucket.org:corddesign/voltha.git
+cd voltha
+vagrant up  # when you do this for the first time, this will take considerable time
+vagrant ssh # the rest to be executed inside the vagrant VM
+cd /voltha
+. env.sh
+make fetch
+make
+```
+
+The above has generated a new Docker image '''cord/voltha''' inside the VM. To see it, run:
+
+```
+docker images
+```
+
+### Run in stand-alone mode
+
+The simplest way to run the image (in the foreground):
+
+```
+docker run -ti --rm cord/voltha
+```
+
+Unless you happen to have a consul agent running on your local system, you shall see that voltha is trying to connect to a consul agent, without success.
+
+To bring up a consul agent, you can use docker-compose with the provided compose file:
+
+```
+docker-compose -f compose/docker-compose-system-test.yml up -d consul
+```
+
+You may get a warning from docker-compose about an empty environment variable, which you can ignore for now.
+
+By now you should have consul running, which you can verify:
+
+```
+docker-compose -f compose/docker-compose-system-test.yml ps
+```
+
+To verify that consul is indeed up, you can point your web browser to [http://localhost:8500/ui](http://localhost:8500/ui).
+Alternatively, you can use curl to access consul's REST API. For example:
+
+```
+curl -s http://localhost:8500/v1/status/leader | jq -r .
+```
+
+This should print the IP address (on the docker network) and port number of the internal gossip API for our consul instance (you can ignore the actual data).
+
+Once consul is up, you can extract its IP address programmatically by:
+
+```
+CONSUL_IP=`docker inspect compose_consul_1 | \
+    jq -r '.[0].NetworkSettings.Networks.compose_default.IPAddress'`
+```
+
+With the IP address in hand, you can now start Voltha manually as:
+
+```
+docker run -ti --rm --net=compose_default cord/voltha /voltha/main.py --consul=$CONSUL_IP:8500
+```
+
+This time it should successfully connect to consul and actually register itself.
+You should see a log line simialr to the following:
+
+```
+<timestamp> INFO     coordinator.register {name: voltha-1, address: localhost, event: registered-with-consul}
+```
+
+To test Voltha's self-registration with consul, run this (in another terminal):
+
+```
+curl -s http://localhost:8500/v1/kv/service/voltha/members?recurse | jq -r .
+```
+
+This should print one key-value entry, something similar to:
+
+```
+[
+  {
+    "ModifyIndex": 19,
+    "CreateIndex": 19,
+    "Session": "139181ff-d4f8-d11c-c450-c41de4baa7d7",
+    "Value": "YWxpdmU=",
+    "Flags": 0,
+    "Key": "service/voltha/members/23d0f3db5877",
+    "LockIndex": 1
+  }
+]
+```
+
+The above is an ephemeral record in consul. To see how it is auto-deleted, stop the voltha container (with Ctrl-C) and rerun the above curl query again. This time you should no output form the query.
+
+To clean up, stop consul:
+
+```
+docker-compose -f compose/docker-compose-system-test.yml stop
+docker-compose -f compose/docker-compose-system-test.yml rm -f
+```
+
+### Run with the "voltha ensamble"
+
+Voltha's intended use is with a consul+fluent+registrator combo. You can bring up this entire ensamble in a developer mode, with just one command. But first, you need to setup your local environment variable. This needs to be done only once in a terminal session:
+
+```
+source env.sh
+```
+
+To start the four-conatiner ensamble:
+
+```
+docker-compose -f compose/docker-compose-system-test.yml up -d
+```
+
+There are a lot of things going on between these containers:
+
+1. To verify that they are all up and happy, you can use:
+
+   ```
+   docker-compose -f compose/docker-compose-system-test.yml ps
+   ```
+   
+   Naturally, you can always use plan docker commands too:
+   
+   ```
+   docker ps -a
+   ```
+   
+2. The registrator container is auto-registering docker containers and their services with consul. This will be handy when accessing the voltha cluster from the north-bound. To see the auto-registrations via Consul's HTTP API:
+
+   ```
+   curl -s http://localhost:8500/v1/catalog/services | jq -r .
+   ```
+   
+   This shall list something like this:
+   
+   ```
+   {
+     "voltha-rest": [],
+     "fluentd-intake": [],
+     "consul-rest": [],
+     "consul-8600": [
+       "udp"
+     ],
+     "consul": []
+   }
+   ```
+   
+   You don't see registrator istelf, and you see multiple entries for consul. More importantly you see voltha as a service called "voltha-rest" (referring to the REST service of voltha). You can query additional info on this endpoint from consul:
+   
+   ```
+   curl -s http://localhost:8500/v1/catalog/service/voltha-rest | jq -r .
+   ```
+   
+   This will provide the complete service record for the voltha instance:
+   
+   ```
+   [
+     {
+       "ModifyIndex": 14,
+       "CreateIndex": 9,
+       "ServiceEnableTagOverride": false,
+       "Node": "ff30117fb001",
+       "Address": "172.18.0.3",
+       "TaggedAddresses": {
+         "wan": "172.18.0.3",
+         "lan": "172.18.0.3"
+       },
+       "ServiceID": "ef1b466f2ede:compose_voltha_1:8880",
+       "ServiceName": "voltha-rest",
+       "ServiceTags": [],
+       "ServiceAddress": "10.0.2.15",
+       "ServicePort": 32768
+     }
+   ]
+   ```
+
+3. Voltha is logging to its standard output, which is captured by docker. There are multiple ways to access this log stream:
+  
+   To see (and tail) logs form all running containers that are part of the voltha: 
+  
+   ```
+   docker-compose -f compose/docker-compose-system-test.yml logs
+   ```
+  
+   Once important thing you can see is that voltha uses structured logging, which will come handy once we utilize macihine parsing and filtring of the logs.
+  
+   Alternatively, you can see the individual docker log stream of voltha by:
+  
+   ```
+   docker logs -f compose_voltha_1
+   ```
+  
+   Voltha sends a periodic log message (heartbeat) to the log stream, in addition to logging major events.
+
+
+4. In addition to the docker log stream, Voltha is explicitly hooked up to the fluentd log collector infrastructure. We are not using fluentd to its full potential yet, but establising the connection to fluentd and funelling structured logs to fluentd is already in place. To see the fluentd log stream, you can run:
+  
+   ```
+   tail -F /tmp/fluentd/*.log
+   ```
+  
+5. When regstrator registers voltha with consul, it also initiates a periodic healt-check from consul to the voltha instance. This is done by calling the ```http://<voltha-instance-ip>:<port>/health``` REST API of voltha. This does not yet do too much, but helps consul to flag a voltha instance "failing" should it not reply to the REST request in a timely manner.
+  
+   If you look into the lo stream of voltha, you can see an entry every 3 seconds indicating that voltha received the health check request and responded (you need -v (verbose mode) enabled to see these).
+  
+   One way to see the health checks are passing is to point your browser to the user interface of consul: [http://10.100.198.220:8500/ui](http://10.100.198.220:8500/ui). Click on the voltha-rest entry and you shall see its passing two health tests, the one with the name volta-rest is our healthcheck.
+  
+6. Consul exposes the service records also as a DNS server. This is how it can be used:
+
+   To check the IP address(es) for voltha's REST interface, you can use:
+   
+   ```
+   dig @localhost -p 8600 voltha-rest.service.consul
+   ```
+   
+   Which shall print, among other things an A record:
+   
+   ```
+   voltha-rest.service.consul. 0  	IN     	A      	10.0.2.15
+   ```
+   
+   Or if you want the IP adress only:
+   
+   ```
+   dig @localhost -p 8600 +short voltha-rest.service.consul
+   ```
+   
+   Which shall print just an IP address.
+   
+   If you want the exposed service port as well:
+   
+   ```
+   dig @localhost -p 8600 +short voltha-rest.service.consul SRV
+   ```
+   
+   The 3rd field in the response is the exposed TCP port voltha's REST API is accessible.
+   
+7. Now something really cool: voltha can be scaled out horizontally to multiple containers by:
+
+   ```
+   docker-compose -f compose/docker-compose-system-test.yml scale voltha=10
+   ```
+   
+   This will bring up nine (9) additional voltha instances as new docker containers. After this completes we encourage you to re-run steps 5, 6 and 7, and observe the changes.
+   
+Finally, you can clean up:
+
+To stop all docker instances started by docker-compose, just run:
+
+```
+docker-compose -f compose/docker-compose-system-test.yml stop
+docker-compose -f compose/docker-compose-system-test.yml rm -f
+```
+
+Or, you can just wipe out your whole Vagrant instance:
+
+```
+exit # from vagrant box back to your native environmnet
+vagrant destroy -f
+```
+
+# Building natively on MAC OS X
+
+For advanced developers this may provide a more comfortable developer
+environment (e.g., by allowing IDE-assisted debugging), but setting it up
+can be a bit more challenging.
+
+### Prerequisites
+
+* git installed
+* Docker-for-Mac installed
+* Python 2.7
+* virtualenv
+* brew (or macports if you prefer)
+
+### Installing Voltha dependencies
+
+The steps that may work (see list of workarounds in case it does not):
+
+```
+git clone git@bitbucket.org:corddesign/voltha.git
+cd voltha
+make venv
+```
+
+Potential issues and workaround:
+
+1. Missing virtualenv binary. Resolution: install virtualenv.
+
+   ```
+   brew install python pip virtualenv
+   ```
+
+1. 'make venv' exits with error 'openssl/opensslv.h': file not found.
+   Resolution: install openssl-dev and add a CFLAGS to make venv:
+
+   MAC OS:
+   ```
+   brew install openssl
+   ```
+
+   Linux:
+   ```
+   sudo apt-get install libssl-dev
+   ```
+
+   Note the version that it installed. For example, '1.0.2h_1'.
+   Rerun ```make venv``` as:
+
+   ```
+   env CFLAGS="-I /usr/local/Cellar/openssl/1.0.2h_1/include" make venv
+   ```
+
+### Building Docker Images and Running Voltha
+
+These steps are not different from the Vagrant path:
+
+```
+make
+```
+
+Then you shall be able to see the created image and run the container:
+
+```
+docker run -ti cord/voltha
+```
+
+After this, much or all of the things you can do inside the Vagrant box should also work natively on the Mac.

+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.

+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only

+# VOLTHA
+
+## What is Voltha?
+
+Voltha aims to provide a layer of abstraction on top of legacy and next generation access network equipment for the purpose of control and management. Its initial focus is on PON (GPON, EPON, NG PON 2), but it aims to go beyond to eventually cover other access technologies (xDSL, Docsis, G.FAST, dedicated Ethernet, fixed wireless).
+
+Key concepts of Voltha:
+
+* **Network as a Switch**: It makes a set of connected access network devices to look like a(n abstract) programmable flow device, a L2/L3/L4 switch. Examples:
+    * PON as a Switch
+    * PON + access backhaul as a Switch
+    * xDSL service as a Switch
+* **Evolution to virtualization**: it can work with a variety of (access) network technologies and devices, including legacy, fully virtualized (in the sense of separation of hardware and software), and in between. Voltha can run on a decice, on general purpose servers in the central office, or in data centers.
+* **Unified OAM abstraction**: it provides unified, vendor- and technology agnostic handling of device management tasks, such as service lifecycle, device lifecycle (including discovery, upgrade), system monitoring, alarms, troubleshooting, security, etc.
+* **Cloud/DevOps bridge to modernization**: it does all above while also treating the abstracted network functions as software services manageable much like other software components in the cloud, i.e., containers.
+
+## Why Voltha?
+
+Control and management in the access network space is a mess. Each access technology brings its own bag of protocols, and on top of that vendors have their own interpretation/extension of the same standards. Compounding the problem is that these vendor- and technology specific differences ooze way up into the centralized OSS systems of the service provider, creating a lot of inefficiencies.
+
+Ideally, all vendor equipment for the same access technology should provide an identical interface for control and management. Moreover, there shall be much higher synergies across technologies. While we wait for vendors to unite, Voltha provides an increment to that direction, by confining the differences to the locality of access and hiding them from the upper layers of the OSS stack.
+
+
+## How can you work with Voltha?
+
+While we are still at the early phase of development, you can check out the [BUILD.md](BUILD.md) file to see how you can build it, run it, test it, etc.
+
+## How can you help?
+
+Contributions, small and large, are welcome. Minor contributions and bug fixes are always welcome in form of pull requests. For larger work, the best is to check in with the existing developers to see where help is most needed and to make sure your solution is compatible with the general philosophy of Voltha.

+## Next Steps Planned
+
+- [DONE] Adding health-check to voltha (and consul)
+- [Z] Adding membership tracking
+- [Z] Adding leader election
+- [Z] Work out a load sharding mechanism
+
+- [N] Add flake8 support (make or part of build)
+- [N] Coverage support and have coverage report hooked up to make
+
+- [Z] Add documentation for the existing docker-compose based system
+- [?] Add system test for the above
+
+- [N] Move in the openflow (lexi) code base
+- [N] Move in the EOAM and/or Tibit TAL
+- [N] Decide where olt-oftest should live: keep as external package
+      or replicate
+
+- [N] make system-test:
+  - fire up a docker ensable using docker-compose
+  - optionally configure network access to device(s)
+  - make sure olt-ofagent test code is available
+  - execute relevant test(s)
+
+- Mock adapter
+
+
+## Next hackaton
+
+- [?] Flash out internal APIs
+
+
+## Architectural questions
+
+- Place a set of internal queues between the layers, or just use
+  direct Twisted async calls
+- Primary data format for internal abstract API in/out data:
+  - Type-specific Python classes with self-contained schema enforcement
+  - "JSON data" == nested Python OrederDict; schema enforcement is
+    implemented in key points in the architecture
+

+
+   TERMS AND CONDITIONS FOR USE, REPRODUCTION, AND DISTRIBUTION
+
+   1. Definitions.
+
+      "License" shall mean the terms and conditions for use, reproduction,
+      and distribution as defined by Sections 1 through 9 of this document.
+
+      "Licensor" shall mean the copyright owner or entity authorized by
+      the copyright owner that is granting the License.
+
+      "Legal Entity" shall mean the union of the acting entity and all
+      other entities that control, are controlled by, or are under common
+      control with that entity. For the purposes of this definition,
+      "control" means (i) the power, direct or indirect, to cause the
+      direction or management of such entity, whether by contract or
+      otherwise, or (ii) ownership of fifty percent (50%) or more of the
+      outstanding shares, or (iii) beneficial ownership of such entity.
+
+      "You" (or "Your") shall mean an individual or Legal Entity
+      exercising permissions granted by this License.
+
+      "Source" form shall mean the preferred form for making modifications,
+      including but not limited to software source code, documentation
+      source, and configuration files.
+
+      "Object" form shall mean any form resulting from mechanical
+      transformation or translation of a Source form, including but
+      not limited to compiled object code, generated documentation,
+      and conversions to other media types.
+
+      "Work" shall mean the work of authorship, whether in Source or
+      Object form, made available under the License, as indicated by a
+      copyright notice that is included in or attached to the work
+      (an example is provided in the Appendix below).
+
+      "Derivative Works" shall mean any work, whether in Source or Object
+      form, that is based on (or derived from) the Work and for which the
+      editorial revisions, annotations, elaborations, or other modifications
+      represent, as a whole, an original work of authorship. For the purposes
+      of this License, Derivative Works shall not include works that remain
+      separable from, or merely link (or bind by name) to the interfaces of,
+      the Work and Derivative Works thereof.
+
+      "Contribution" shall mean any work of authorship, including
+      the original version of the Work and any modifications or additions
+      to that Work or Derivative Works thereof, that is intentionally
+      submitted to Licensor for inclusion in the Work by the copyright owner
+      or by an individual or Legal Entity authorized to submit on behalf of
+      the copyright owner. For the purposes of this definition, "submitted"
+      means any form of electronic, verbal, or written communication sent
+      to the Licensor or its representatives, including but not limited to
+      communication on electronic mailing lists, source code control systems,
+      and issue tracking systems that are managed by, or on behalf of, the
+      Licensor for the purpose of discussing and improving the Work, but
+      excluding communication that is conspicuously marked or otherwise
+      designated in writing by the copyright owner as "Not a Contribution."
+
+      "Contributor" shall mean Licensor and any individual or Legal Entity
+      on behalf of whom a Contribution has been received by Licensor and
+      subsequently incorporated within the Work.
+
+   2. Grant of Copyright License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      copyright license to reproduce, prepare Derivative Works of,
+      publicly display, publicly perform, sublicense, and distribute the
+      Work and such Derivative Works in Source or Object form.
+
+   3. Grant of Patent License. Subject to the terms and conditions of
+      this License, each Contributor hereby grants to You a perpetual,
+      worldwide, non-exclusive, no-charge, royalty-free, irrevocable
+      (except as stated in this section) patent license to make, have made,
+      use, offer to sell, sell, import, and otherwise transfer the Work,
+      where such license applies only to those patent claims licensable
+      by such Contributor that are necessarily infringed by their
+      Contribution(s) alone or by combination of their Contribution(s)
+      with the Work to which such Contribution(s) was submitted. If You
+      institute patent litigation against any entity (including a
+      cross-claim or counterclaim in a lawsuit) alleging that the Work
+      or a Contribution incorporated within the Work constitutes direct
+      or contributory patent infringement, then any patent licenses
+      granted to You under this License for that Work shall terminate
+      as of the date such litigation is filed.
+
+   4. Redistribution. You may reproduce and distribute copies of the
+      Work or Derivative Works thereof in any medium, with or without
+      modifications, and in Source or Object form, provided that You
+      meet the following conditions:
+
+      (a) You must give any other recipients of the Work or
+          Derivative Works a copy of this License; and
+
+      (b) You must cause any modified files to carry prominent notices
+          stating that You changed the files; and
+
+      (c) You must retain, in the Source form of any Derivative Works
+          that You distribute, all copyright, patent, trademark, and
+          attribution notices from the Source form of the Work,
+          excluding those notices that do not pertain to any part of
+          the Derivative Works; and
+
+      (d) If the Work includes a "NOTICE" text file as part of its
+          distribution, then any Derivative Works that You distribute must
+          include a readable copy of the attribution notices contained
+          within such NOTICE file, excluding those notices that do not
+          pertain to any part of the Derivative Works, in at least one
+          of the following places: within a NOTICE text file distributed
+          as part of the Derivative Works; within the Source form or
+          documentation, if provided along with the Derivative Works; or,
+          within a display generated by the Derivative Works, if and
+          wherever such third-party notices normally appear. The contents
+          of the NOTICE file are for informational purposes only and
+          do not modify the License. You may add Your own attribution
+          notices within Derivative Works that You distribute, alongside
+          or as an addendum to the NOTICE text from the Work, provided
+          that such additional attribution notices cannot be construed
+          as modifying the License.
+
+      You may add Your own copyright statement to Your modifications and
+      may provide additional or different license terms and conditions
+      for use, reproduction, or distribution of Your modifications, or
+      for any such Derivative Works as a whole, provided Your use,
+      reproduction, and distribution of the Work otherwise complies with
+      the conditions stated in this License.
+
+   5. Submission of Contributions. Unless You explicitly state otherwise,
+      any Contribution intentionally submitted for inclusion in the Work
+      by You to the Licensor shall be under the terms and conditions of
+      this License, without any additional terms or conditions.
+      Notwithstanding the above, nothing herein shall supersede or modify
+      the terms of any separate license agreement you may have executed
+      with Licensor regarding such Contributions.
+
+   6. Trademarks. This License does not grant permission to use the trade
+      names, trademarks, service marks, or product names of the Licensor,
+      except as required for reasonable and customary use in describing the
+      origin of the Work and reproducing the content of the NOTICE file.
+
+   7. Disclaimer of Warranty. Unless required by applicable law or
+      agreed to in writing, Licensor provides the Work (and each
+      Contributor provides its Contributions) on an "AS IS" BASIS,
+      WITHOUT WARRANTIES OR CONDITIONS OF ANY KIND, either express or
+      implied, including, without limitation, any warranties or conditions
+      of TITLE, NON-INFRINGEMENT, MERCHANTABILITY, or FITNESS FOR A
+      PARTICULAR PURPOSE. You are solely responsible for determining the
+      appropriateness of using or redistributing the Work and assume any
+      risks associated with Your exercise of permissions under this License.
+
+   8. Limitation of Liability. In no event and under no legal theory,
+      whether in tort (including negligence), contract, or otherwise,
+      unless required by applicable law (such as deliberate and grossly
+      negligent acts) or agreed to in writing, shall any Contributor be
+      liable to You for damages, including any direct, indirect, special,
+      incidental, or consequential damages of any character arising as a
+      result of this License or out of the use or inability to use the
+      Work (including but not limited to damages for loss of goodwill,
+      work stoppage, computer failure or malfunction, or any and all
+      other commercial damages or losses), even if such Contributor
+      has been advised of the possibility of such damages.
+
+   9. Accepting Warranty or Additional Liability. While redistributing
+      the Work or Derivative Works thereof, You may choose to offer,
+      and charge a fee for, acceptance of support, warranty, indemnity,
+      or other liability obligations and/or rights consistent with this
+      License. However, in accepting such obligations, You may act only
+      on Your own behalf and on Your sole responsibility, not on behalf
+      of any other Contributor, and only if You agree to indemnify,
+      defend, and hold each Contributor harmless for any liability
+      incurred by, or claims asserted against, such Contributor by reason
+      of your accepting any such warranty or additional liability.
+
+   END OF TERMS AND CONDITIONS
+
+   APPENDIX: How to apply the Apache License to your work.

+// `HttpRule` defines the mapping of an RPC method to one or more HTTP REST API
+// methods. The mapping determines what portions of the request message are
+// populated from the path, query parameters, or body of the HTTP request.  The
+// mapping is typically specified as an `google.api.http` annotation, see
+// "google/api/annotations.proto" for details.
+//
+// The mapping consists of a mandatory field specifying a path template and an
+// optional `body` field specifying what data is represented in the HTTP request
+// body. The field name for the path indicates the HTTP method. Example:
+//
+// ```
+// package google.storage.v2;
+//
+// import "google/api/annotations.proto";
+//
+// service Storage {
+//   rpc CreateObject(CreateObjectRequest) returns (Object) {
+//     option (google.api.http) {
+//       post: "/v2/{bucket_name=buckets/*}/objects"
+//       body: "object"
+//     };
+//   };
+// }
+// ```
+//
+// Here `bucket_name` and `object` bind to fields of the request message
+// `CreateObjectRequest`.
+//
+// The rules for mapping HTTP path, query parameters, and body fields
+// to the request message are as follows:
+//
+// 1. The `body` field specifies either `*` or a field path, or is
+//    omitted. If omitted, it assumes there is no HTTP body.
+// 2. Leaf fields (recursive expansion of nested messages in the
+//    request) can be classified into three types:
+//     (a) Matched in the URL template.
+//     (b) Covered by body (if body is `*`, everything except (a) fields;
+//         else everything under the body field)
+//     (c) All other fields.
+// 3. URL query parameters found in the HTTP request are mapped to (c) fields.
+// 4. Any body sent with an HTTP request can contain only (b) fields.
+//
+// The syntax of the path template is as follows:
+//
+//     Template = "/" Segments [ Verb ] ;
+//     Segments = Segment { "/" Segment } ;
+//     Segment  = "*" | "**" | LITERAL | Variable ;
+//     Variable = "{" FieldPath [ "=" Segments ] "}" ;
+//     FieldPath = IDENT { "." IDENT } ;
+//     Verb     = ":" LITERAL ;
+//
+// `*` matches a single path component, `**` zero or more path components, and
+// `LITERAL` a constant.  A `Variable` can match an entire path as specified
+// again by a template; this nested template must not contain further variables.
+// If no template is given with a variable, it matches a single path component.
+// The notation `{var}` is henceforth equivalent to `{var=*}`.
+//
+// Use CustomHttpPattern to specify any HTTP method that is not included in the
+// pattern field, such as HEAD, or "*" to leave the HTTP method unspecified for
+// a given URL path rule. The wild-card rule is useful for services that provide
+// content to Web (HTML) clients.
+message HttpRule {
+
+  // Determines the URL pattern is matched by this rules. This pattern can be
+  // used with any of the {get|put|post|delete|patch} methods. A custom method
+  // can be defined using the 'custom' field.

+NOTE: This command should soon be eliminated as the adapter should

+## oftest test-cases to test the pyofagent
+
+The main purpose of these tests is to verify correct packet-in and packet-out behavior of
+pyofagent. Pyofagent can send and receive raw packets at a local interface. The interface
+can be configured with the --in-out-iface=<link name> command line option. We will refer
+to this interface below as the "in-out" interface.
+
+Incoming frames arriving at the in-out interface are assumed to be single-tagged with a VLAN
+id that represents a logical port number. Pyofagent will forward such frames to the controller
+as OpenFlow "packet-in" messages, accompanied with the extracted port number is in_port
+metadata.
+
+Conversely, when pyofagent receives an OpenFlow "packet-out" message from the controller, it
+will encapsualte the frame in an VLAN header with a VLAN id representing the out_port. If the
+out_port is a list, pyofagent will replicate the frame and send it out once at each specified
+port (that is, one with each of the specified VLAN ids).
+
+### Setup required for the test:
+
+You must have oftest checked out in a directory at the same level as the pyofagent root directory.
+For instance, if pyofagent is under ~/olt, then oftest must be checked out also under ~/olt:
+
+```
+cd ~/olt
+git clone git@bitbucket.org:corddesign/pyofagent.git
+```
+
+In order to run these test, we need to create a veth port pair on the host:
+
+```
+sudo ip link add ep1 type veth peer name ep2
+sudo ifconfig ep1 up
+sudo ifconfig ep2 up
+```
+
+To start pyofagent in the in-out mode, start it with the --in-out-iface option, such as:
+
+```
+cd ~/olt
+sudo python pyofagent/pyofagent/main.py -v --in-out-iface=ep2
+```
+
+Now we can run the tests:
+
+```
+cd ~/olt
+sudo ./oftest/oft --test-dir=pyofagent/oftest/ -i 1@ep1 --port 6633 -V 1.3 \
+        --debug=verbose -t "in_out_port=1"
+```
+
+There are currently two tests, they should both pass. This proves that the packet in/out behavior of pyofagent is healthy.
