ONF Connect 2019

The recent releases of ONF Transport API (TAPI)  have been focused on management, control and orchestration of connectivity-services across a multi-layer, multi-domain transport network topology. This presentation utilizes an real world scenario of an MEF 63 Subscriber L1 Service over an dis-aggregated photonic network to illustrate key TAPI concepts related to Topology. Concepts such as component-system pattern, recursive node-topology abstraction, partitioning & layering, etc will be introduced and relationship of TAPI Topology to IETF Topology (RFC 8345) will be explored.
