Scalable Telemetry and Network Autonomics in ACTN SDN Controller Hierarchy

摘要

Abstraction and Control of TE Networks (ACTN) refers to the set of virtual network operations needed to operate, control and manage large-scale multi-domain, multi-layer and multi-vendor TE networks, so as to facilitate network programmability, automation, efficient resource sharing. This paper provides scalable telemetry streaming mechanisms that describe Key Performance Indicator (KPI) telemetry and network autonomics in the context of ACTN SDN controller hierarchy.
