Abstract
In one embodiment, a stateful computing entity in a computer network determines underlying network information (physical and/or optical) for the computer network, and also determines topologies (Internet Protocol (IP) and/or Multiprotocol Label Switching (MPLS)) for the computer network and associated resource information. Further, the stateful computing entity determines label switched path (LSP) state information for the computer network. The stateful computing entity may then build network state knowledge by aggregating the underlying network information, the topologies and associated resource information, and the LSP state information, and establishes communication within a dynamic network of other stateful computing entities sharing network state knowledge for parallel computation performance. Accordingly, the stateful computing entity may perform network computation based on the network state knowledge.
