Hi Glen.

In SDN world you need to open up your network for external applications/controllers to understand the network resources available for them, retrieve various network telemetry, control their services placement and optimization, etc. TE topology model provides a standardized schema on how the network’s Traffic Engineering Database looks to such applications from remote. Note that the model does not impose any rules or constraints on how the network’s TED organized and managed  locally by the provider.

Cheers,
Igor

Subject: [Teas] Basic question on YANG Data Model for TE Topologies

Hi WG members,

I am new to TEAS and am trying to understand the need to standardise the YANG model for the TE topologies?

Isn't how I model a TE network an internal issue to a system? Why do all vendors need a standardised way to model the TE networks. Its not something thats exchanged between two different vendors. Can somebody help me here?
