VOLTHA 2.4 Release Notes ======================== Highlights ---------- VOLTHA 2.4 together with ONOS 2.2.3 is the first release with full support for all 3 operator workflows - AT&T’s 1 TCONT- 4 GEMs, Deutsche Telekom’s FTTH 1 TCONT- 8 GEMs, and Turk Telekom’s Multi-TCONT triple-play workflows. Also, for the first time, this release supports whitebox GPON OLTs and in-band management of remotely-located OLTs. It improves on performance and scale, achieving the MVP 1.0 requirements for production deployments of 2 OLTs with 500 ONUs each for the AT&T and DT workflows. The release also expands on automated-tests, with over 100+ tests run nightly in regression testing jobs across 3 hardware pods, delivering improved stability and robustness. VOLTHA 2.4 also comes on top of up-to-date versions of key infrastructure components such as HELM 3 and Kubernetes 1.18. Features & Improvements ----------------------- - Full support for Turk Telekom triple play workflow with HSIA, Multicast IPTV, VoIP and VoD using T-CONTS per service. Two new ONOS apps introduced - igmp-proxy and mcast - Support for multiple OLTs in a single-VOLTHA stack. - Support for GPON OLTs, specifically EdgeCore’s ASGvOLT64 OLT - Support for ONOS controller clustering (typically with 3 ONOS instances and 3 Atomix instances) for scale and high availability. All 7 ONOS applications used with VOLTHA upgraded to work in a clustered setting. - Support for multiple ONU adaptor instances for scaling out (internal to a VOLTHA stack) - Support for In-band Management of OLTs - BAL transitioned from version 3.2.3.2 to version 3.4.3.3 with several bug fixes - Full DT and ATT workflow support on BBSIM simulator for scale testing - Scale improvements to meet MVP 1 targets of 2 OLTs with 500 ONUs each for both DT and ATT workflows, including several improvements to VOLTHA core data models. - Enhanced Meter handling for Bandwidth profile support. - Enhanced Group handling and cleanup. Development process ------------------- - Update to Kubernetes 1.18.5 - Update to Helm3 of all the charts and deployment tools. Testing ------- - Integration Tests - Automated tests run on both hardware and BBSim platforms, please use the VOLTHA-2.4 view under https://jenkins.opencord.org/ - Sanity test on hardware for TT workflow - In Band Management of OLT on one of the ONF Menlo testing pods - GPON OLT test job in Berlin pod - Scale Tests - Met required scale measurements with 2 OLTs and 500 ONUs each for both ATT and DT workflows Documentation ------------- - Updated documentation with workflow specific orientation and published on https://docs.voltha.org Known Issues ------------ - [VOL-3376] Data rate error margin beyond allowed limit - [VOL-3377] In-band interface does not get an IP address from DHCP sometimes due to an issue in BAL.
