Abstract:
This disclosure describes techniques for implementing centralized path computation for routing in hybrid information-centric networking protocols implemented as a virtual network overlay. A method includes receiving an interest packet header from a forwarding router node of a network overlay. The method further includes determining an interest path of the interest packet and one or more destination router nodes of the network overlay. The method further includes computing one or more paths over the network overlay. The method further includes determining an addressing method for the one or more computed paths over the network overlay. The method further includes performing at least one of encoding each computed path in a data packet header, and encoding each computed path as state entries of each router node of the network overlay on each respective path. The method further includes returning the computed path information to the forwarding router node.
