| VOLTHA 2.8 Release Notes |
| ======================== |
| |
| Highlights |
| ---------- |
| |
| VOLTHA-2.8 is the first Long Term Support (LTS) release for VOLTHA. Together with ONOS 2.5 (which is already LTS), |
| the LTS designation means that testing and bug-fixes will be guaranteed for 18 months on the released version of the |
| codebase. The release focused on storage with persistence at scale, platform hardening, tcont type selection, Multi-Uni |
| support and introduced several PON level metrics. All these elements provide confidence to the operators to expand |
| their production deployments. |
| |
| The Long Term Support process is as follows: |
| |
| - LTS releases 18 months apart. |
| - Each LTS release will be supported for 18 months with bug fixes and testing |
| - 6 month release cycles following LTS release |
| - Two interim releases every 6 months between LTS versions. |
| |
| VOLTHA 2.8 first and foremost meets the scale requirements (1024 ONUS per stack, 10240 on 10 stack across the same |
| infrastructure) of the operator’s with persistence enabled on ETCD 6.13.19 version, deployed with the BITNAMI helm |
| charts. Such result was achieved thanks to the combination of several improvements across the whole stack. |
| The Technology profile is now mostly templated, the openolt adapter makes heavier use of the read-through cache, |
| the rw-core does not store the flows for each device. A ETCD connection pool has been introduced in voltha-lib-go |
| to ensure that the system is not choking by using 1 connection per service. With all these improvements on NVMe |
| disks all 3 workflows provision 1024 subscribers in around 2 minutes. |
| |
| During the VOLTHA 2.8 release ONOS was moved from the 2.2 release which is shortly approaching EOL (end of life) to |
| ONOS 2.5, guaranteeing that for the extent of the 2.8 release also ONOS will be supported. |
| |
| To support more customers in the field multi-UNI capability has been introduced across the VOLTHA stack and ONOS apps. |
| The system is now capable of delivering configuration and thus traffic to subscribers connected to all UNI ports |
| of each ONU, up to 16 per ONU. |
| |
| Further subscriber configuration has been introduced with the support for the IETF model for bandwidth profiles |
| and the capability to provision and choose all the 5 TCONT types. These elements allow operator’s a wider variety |
| of subscriber configurations |
| |
| To comply with operator requirements the ONU software upgrade APIs have been changed to support retrieval of images |
| present on the ONU and to separate the download, activate, commit, requests, allowing the operator more control over |
| the actions performed over the ONU. Furthermore hardening of the functionality has been done, achieving a much faster |
| ONU update time. |
| |
| Further insight into live deployed networks has been introduced thanks to more Performance Measurements that can be |
| retrieved from the ONU and the OLT. In particular VOLTHA 2.8 implements ANi-G and ANi-G test messages with tx/rx |
| power readout, ONUi-PON, GEMj and UNI Ethernet layer, FEC and GEM history and several other counters. |
| |
| Finally the release provided bug fixes across the stack, especially concerning device/port handling, such as, |
| PON enable/disable, OLT and ONU reboot and ONU software upgrade. Performance related improvements were included |
| in ONOS apps. VOLTHA 2.8 hardened several operations, one worth noting is the omci message retry on failure in |
| openonu adapter |
| |
| On the testing front VOLTHA 2.8 expanded the suite for TT up to 20 tests, with failure and error scenarios, |
| including several multi TCONT testing as per TT workflow. Testing has included also a full suite for the |
| Performance Measurements functionality, especially ANI-G. Furthermore we included support for multi-uni in the robot |
| suite and expanded the soak testing with DT workflow. |
| |
| Along with VOLTHA 2.8, the Device Management Brigade also released a new version |
| (`1.0.0 <https://github.com/opencord/device-management-interface/releases/tag/v1.0.0>`_) of the interface, |
| which has been implemented on BBSIM and has initial robot test cases. This DMI release introduces specific components |
| values, BITS protocol, gRPC streams for events and metrics that can be use in place of kafka, more events and |
| a heart beat check. |
