Vertex-centric service function chaining in multi-domain networks
Systems and methods for performing vertex-centric service function chaining in multi-domain networks are disclosed. A resource orchestration framework of a multi-domain network may include vertices representing physical nodes and edges representing physical links in the network. A sole resource orchestrator (in a centralized system) or multiple resource orchestrators (each associated with a respective domain in a distributed system) may coordinate execution of a common compute function on multiple vertices to identify candidate service function chain solutions to a service function chain request. The request may specify a fixed-ordered chain or a flexible-ordered chain. The compute function may, during each of multiple supersteps, determine whether a partially mapped chain can be extended on a given vertex, send a controller message to a neighbor vertex with which it has a qualified link, or return a completed chain, which may be selected for execution, dependent on applicable policies.
