Abstract
A method and system for managing connections with a distributed control plane is provided. The method includes generating, by a router, a controller identifier (ID) list comprising a plurality of controller group IDs of a plurality of controller groups, wherein one controller group ID uniquely identifies one controller group. The method also includes identifying a first controller group, by the router from the list, with which a connection is to be established. Further, the method includes establishing, by the router, the connection with a controller of the first controller group if at least one of following conditions is met I) the router has not exhausted maximum number of connections, 2) the router has previously had a connection with the controller of the first controller group, and 3) the router has an existing connection with a controller of a second controller group not present in the list.
