Embodiment Construction

[0030] It should be understood at the outset that although an illustrative implementation of one or more embodiments is provided below, the disclosed systems and / or methods may be implemented using any number of currently known or available techniques. The invention should in no way be limited to the illustrative implementations, drawings, and techniques described below, including the exemplary designs and implementations illustrated and described herein, but rather be within the scope of the appended claims and their equivalents. Modified in full.

[0031] In today's networks, border nodes such as gateway routers can serve as communication gateways between end nodes and other border nodes within the overlay network. To facilitate communication, border nodes may map the addresses of end nodes to other border nodes. For example, an ingress border node may receive a data packet from a source end node in an overlay network and map a destination address in the data packet to an e...

Abstract

A network node comprising a processor configured to maintain a plurality of mapping entries for one or more virtual network instances, receive a data packet within a first virtual network instance, wherein the data packet comprises an inner destination address, match the inner destination address with one of the mapping entries, obtain an outer destination address that corresponds to the matched mapping entry, encapsulate the data packet with the outer destination address, and forward the encapsulated data packet based on the outer destination address, wherein the mapping entries maps out all of the addresses for a plurality of end nodes that participate in the first virtual network instance.

[0001] Related Applications Cross Application [0002] This application claims prior application priority to U.S. Provisional Patent Application No. 61 / 602,935, filed February 24, 2012, by Linda Dunbar et al., entitled "Balance of Forwarding and Address Resolution in Overlay Networks," The content of this prior application is incorporated by reference into this text as if reproduced in its entirety. [0003] About Federal Sponsored [0004] Statement of Research or Development [0005] Not applicable. [0006] References to Microfiche Attachments [0007] Not applicable. Background technique [0008] Virtual and overlay network technologies have greatly improved the implementation of communication and data networks in terms of efficiency, cost, and processing power. An overlay network can be a virtual environment built on top of a service bearer network. Nodes within the overlay network may be connected by virtual and / or logical links, which may correspond to nodes and p...
