NTT and KDDI Challenges for Sustainable Infrastructure Transformation

on YouTube ↗25m

" summary

Telecom operators move a vendor‑specific VNFM to OpenStack Tacker and report concrete results: KDDI runs Tacker for fixed BNGs on 16M subscribers, Tacker adds Kubernetes support, a Heat plugin and Phoenix upgrades, and NEC upstreams fixes like multi‑deployment playbook handling. Project metrics show 141 patches (37% increase) and 26 active contributors in Victoria. QA work integrates ETSI TST010 with Robot Framework and Zuul to automate API conformance tests, but precondition handling and some commercial edge cases still need joint specification and maintenance.
