NETCONF¶
Overview¶
The NETCONF projects hosts multiple components relating to IETF’s NETCONF Working Group:
Northbound and southbound plugins for NETCONF protocol, as described in RFC-6241
Northbound plugin for RESTCONF protocol, as described in RFC-8040
Northnound plugin for descring RESTCONF endpoint in terms of OpenAPI 3.0
Behavior/Feature Changes¶
The transport layer of the NETCONF protocol implementation has been completely refactored. This effort has all but unified the ‘normal’ and ‘call-home’ mode of operation. This results in a more maintaintanable codebase with much easier feature parity between the two modes.
RESTCONF implementation has been been refactored to a large extent, taking advantage of JAX-RS asynchronous requests, so that operations on the datastore and NETCONF devices no longer pin the HTTP thread.
The OpenAPI component has been completely modernized. It is now based on Swagger UI vesion 5.13.0 and is memory usage has been brought under control.
New Features¶
No new features.
Deprecated and Removed Features¶
The odl-yanglib experimental feature has been removed.
