Abstract:
Systems and methods for performing distributed virtual network embedding are disclosed. A resource orchestrator may receive a virtual network request specifying a set of virtual nodes, a set of virtual links, each connecting two virtual nodes in a mesh topology, and resource requirements for some virtual nodes. The orchestrator may partition the virtual network request into multiple sub-requests, each specifying a linear topology for a subset of the virtual nodes and links within the mesh topology. The sub-requests may collectively include all virtual links within the mesh topology with no overlapping links. Resource orchestrators may collaborate to compute, independently for each sub-request, a respective chaining solution in which each virtual node is mapped to a physical node having resources sufficient to implementing the virtual node. A resource orchestrator may combine the respective chaining solutions for each of the sub-requests to generate a mapping solution for the virtual network request.
