Abstract: A method and a system for distributed computation of a routing table for a vast communication network are disclosed. The network nodes are arranged into multiple groups with each group associated with a respective network controller. A network controller of a group acquires characterizing information of links emanating from local nodes of the group, communicates the information to each other network controller, reciprocally receives characterizing information from other network controllers, and determines a generic route set from each local node to each other node of the network. The network controllers collectively determine an inverse routing table identifying all routes traversing each individual link in the entire network and exchange node or link state-transition information for updating individual route sets affected by any state transition. Thus, the processing effort of routes generation and tracking network-elements states is distributed among multiple coordinated network controllers.
