A method and system for implementing a network service computation system uses distributed graph processing at a plurality of network controllers corresponding to a plurality of network domains. Each network controller may manage and maintain a network graph for its respective network domain. Each network controller many communicate with nodes (or vertices) in its respective network domain, while the network controllers may communicate with each other for path discovery and computation purposes.
