Andrea Campanella1865dcb2021-07-10 01:16:45 +02001VOLTHA 2.8 Release Notes
2========================
3
4Highlights
5----------
6
7VOLTHA-2.8 is the first Long Term Support (LTS) release for VOLTHA. Together with ONOS 2.5 (which is already LTS),
8the LTS designation means that testing and bug-fixes will be guaranteed for 18 months on the released version of the
9codebase. The release focused on storage with persistence at scale, platform hardening, tcont type selection, Multi-Uni
10support and introduced several PON level metrics. All these elements provide confidence to the operators to expand
11their production deployments.
12
13The Long Term Support process is as follows:
14
15- LTS releases 18 months apart.
16- Each LTS release will be supported for 18 months with bug fixes and testing
17- 6 month release cycles following LTS release
18- Two interim releases every 6 months between LTS versions.
19
20VOLTHA 2.8 first and foremost meets the scale requirements (1024 ONUS per stack, 10240 on 10 stack across the same
21infrastructure) of the operators with persistence enabled on ETCD 6.2.5 version, deployed with the BITNAMI helm
22charts. Such result was achieved thanks to the combination of several improvements across the whole stack.
23The Technology profile is now mostly templated, the openolt adapter makes heavier use of the read-through cache,
24the rw-core does not store the flows for each device. A ETCD connection pool has been introduced in voltha-lib-go
25to ensure that the system is not choking by using 1 connection per service. With all these improvements on NVMe
26disks all 3 workflows provision 1024 subscribers in around 2 minutes.
27
28During the VOLTHA 2.8 release ONOS was moved from the 2.2 release which is shortly approaching EOL (end of life) to
29ONOS 2.5, guaranteeing that for the extent of the 2.8 release also ONOS will be supported.
30
31To support more customers in the field multi-UNI capability has been introduced across the VOLTHA stack and ONOS apps.
32The system is now capable of delivering configuration and thus traffic to subscribers connected to all UNI ports
33of each ONU, up to 16 per ONU.
34
35Further subscriber configuration has been introduced with the support for the IETF model for bandwidth profiles
36and the capability to provision and choose all the 5 TCONT types. These elements allow operators a wider variety
37of subscriber configurations
38
39To comply with operator requirements the ONU software upgrade APIs have been changed to support retrieval of images
40present on the ONU and to separate the download, activate, commit, requests, allowing the operator more control over
41the actions performed over the ONU. Furthermore hardening of the functionality has been done, achieving a much faster
42ONU update time.
43
44Further insight into live deployed networks has been introduced thanks to more Performance Measurements that can be
45retrieved from the ONU and the OLT. In particular VOLTHA 2.8 implements ANi-G and ANi-G test messages with tx/rx
46power readout, ONUi-PON, GEMj and UNI Ethernet layer, FEC and GEM history and several other counters.
47
48Finally the release provided bug fixes across the stack, especially concerning device/port handling, such as,
49PON enable/disable, OLT and ONU reboot and ONU software upgrade. Performance related improvements were included
50in ONOS apps. VOLTHA 2.8 hardened several operations, one worth noting is the omci message retry on failure in
51openonu adapter
52
53On the testing front VOLTHA 2.8 expanded the suite for TT up to 20 tests, with failure and error scenarios,
54including several multi TCONT testing as per TT workflow. Testing has included also a full suite for the
55Performance Measurements functionality, especially ANI-G. Furthermore we included support for multi-uni in the robot
56suite and expanded the soak testing with DT workflow.
57
58Along with VOLTHA 2.8, the Device Management Brigade also released a new version
59(`1.0.0 <https://github.com/opencord/device-management-interface/releases/tag/v1.0.0>`_) of the interface,
60which has been implemented on BBSIM and has initial robot test cases. This DMI release introduces specific components
61values, BITS protocol, gRPC streams for events and metrics that can be use in place of kafka, more events and
62a heart beat check.
