VOLTHA 2.4 Release Notes¶
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.
