The model defines generic RSVP protocol building blocks that can be augmented and used by other RSVP extension models such as RVSP extensions to Traffic-Engineering (RSVP-TE). The model covers the RSVP protocol configuration, operational state, remote procedural calls, and event notifications data. @@ -81,31 +81,31 @@ 3.1.1.

Introduction YANG [RFC6020] is a data definition language that was introduced to define the contents of a conceptual data store that allows networked devices to be managed using NETCONF [RFC6241]. YANG is proving relevant beyond its initial confines, as bindings to other interfaces (e.g. ReST) and encoding other than XML (e.g. JSON) are being defined. Furthermore, YANG data models can be used as the basis of implementation for other interface, such as CLI and programmatic @@ -2288,111 +2288,149 @@ module ietf-rsvp-te { namespace "urn:ietf:params:xml:ns:yang:ietf-rsvp-te";

RSVP-TE MPLS Model This section describes the MPLS RSVP-TE YANG module that augments the RSVP-TE generic module to signal MPLS LSPs. RSVP-TE YANG modules for other dataplane technologies (e.g. OTN or WDM) will be defined in separate modules and in other drafts.
