Technical Summary

This document specifies a minimal YANG model for TCP on devices that are configured by network management protocols. The YANG model defines a container for all TCP connections and groupings of authentication parameters that can be imported and used in TCP implementations or by other models that need to configure TCP parameters. The model also includes basic TCP statistics. The model is compliant with Network Management Datastore Architecture (NMDA) (RFC 8342).

Working Group Summary

The draft has been active for over 3 years. At first, some raised concerns that other TCP related
YANG models might create conflicts or overlap, and that attempting a model for all of TCP
would be complicated and time-consuming, and TCP implementations would not provide a
YANG-based configuration interface.  Therefore, the focus is limited
to a small set of parameters and TCP configuration on BGP routers, where YANG is already in use.
There have been no other controversial points that required long arguments. There is a solid
consensus in the WG for publication.

Document Quality

There are prototype implementations. A YANG Doctors review is in progress. This work was
requested by people in the BGP community, so we expect industry adoption.
