Abstract:
1. An Internet Protocol network, comprising: a plurality of edge routers; a virtual core router interconnecting the plurality of edge routers; wherein the virtual core router comprises a domain of interconnected optical switches in communication with a packet controller, the domain of interconnected optical switches and the packet controller are configured to cooperatively implement the virtual core router such that the plurality of edge routers view the domain of interconnected optical switches and the packet controller as the virtual core router from a topology perspective; a centralized control plane for packet switching functions on the interconnected optical switches; a distributed control plane for transport switching functions on the interconnected optical switches; and a proxy communicatively coupled to optical switches connected to the plurality of edge routers; wherein the proxy is communicatively coupled to the packet controller, the plurality of edge routers are configured to exchange messages to the packet controller through the optical switches connected to the plurality of edge routers.
