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.
