A method includes determining whether the first version is an alias with respect to the second version, the alias being defined as an equivalent version of the YANG module. Based at least in part on a determination that the first version is the alias with respect to the second version, a version alias extension is inserted into a revision label of the first and/or second version. Based on a determination that the second version is backwards compatible with respect to the first version, a version backwards compatible extension is inserted into the revision label of the second version. Based at least in part on a determination that the second version is not backwards compatible with respect to the first version, a version non-backwards compatible extension is inserted into the revision label of the second version.

Analyzing data module versions for aliases and backwards compatibility

A method and apparatus for communicating and utilizing control plane congestion information in a communication network that utilizes a source routed signaling protocol is presented. When control plane congestion is detected at a network element within the communication network, a congestion notification message is generated corresponding to the detected control plane congestion. The congestion notification is then provided to at least one additional network element within the communications network. The at least one additional network element can then utilize this knowledge of the congestion within the network to perform various network functions, including the routing a connection set-up message.
