Abstract
Disclosed herein is a mechanism for discovering SDN specific topology information in a SDN interconnection network. SDN specific topology information may comprise SDN IDs, SDN member router ID lists, and SDN address lists. A SDNC associated with a local SDN domain in the SDN interconnection network may determine a set of routers and/or links in the local SDN domain for link advertisement and may associate the set of routers with the local SDN domain. The SDNC may further determine a set of border routers in the local SDN domain for broadcasting the link advertisements and SDN specific topology information to other interconnected SDN domains. The SDNC may receive link advertisement and SDN specific topology information from other interconnected SDN domains and may compute a best path through each router and/or link across the SDN domains.
