SYSTEM AND METHOD PROVIDING DISTRIBUTED VIRTUAL ROUTING AND SWITCHING (DVRS)

摘要

Systems, methods, architectures and/or apparatus for providing a distributed Virtual Routing and Switching (dVRS) solution at a data center (DC) by logically representing the networking resources of the data center as a plurality virtual nodes, each virtual node comprising an IP infrastructure based on a physical network node and a plurality of virtual switches, each virtual switch including a VRS instance linked to one or more VRS instances at other virtual switches via a VLAN to provide thereby a virtual service, wherein the physical network node performs control plane processing and provides to each virtual switch the specific routing information associated with the local services of that virtual switch. Thus, from a data plane perspective the virtual switches route and/or switch traffic directly to tunnels pointing to remote VRS instances without involving the Controller in the forwarding of the packets.
