Topology aware provisioning in a software-defined networking environment

摘要

An example method for topology aware provisioning in a software-defined network environment is provided and includes receiving, at a provider edge device (PE), access network topology information associated with a customer edge device in a network environment, synthesizing the access network topology information and a local router information associated with the PE into a topology message, and publishing the topology message to a central controller in the network environment. The synthesizing can include aggregating the access network topology information and the local router information, modeling the aggregated information in a representation-independent format and encoding the representation-independent formatted aggregated information in standardized machine-parsable format.

1. A method, comprising:
receiving, at a provider edge device (PE), access network topology information associated with a customer edge device (CE) in a network environment, the CE in communication with the PE over the network through one or more intermediate access nodes (ANs); synthesizing the access network topology information and a local router information, including hardware inventory associated with the PE into a topology message, the hardware inventory indicative of device information including information about types and versions of line cards in the PE, software and firmware revisions, and transceiver types of the PE; and publishing the topology message to a central controller in the network environment.
