Problems solved by technology

However, the constant flooding of packets within a given virtual network instance can adversely affect network performance, bandwidth, and processing power
Installing additional gateway nodes may not improve network performance, bandwidth, and processing power because each gateway node needs to reach all end nodes participating in a given virtual network instance

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] Disclosed herein is a method, apparatus and system for delegating responsibility for forwarding and address resolution for virtual network instances. An overlay network can be divided into multiple virtual network instances. One or more designated forwarding nodes can be selected to be responsible for all forwarding information of each virtual network instance. A node may announce a virtual network instance that the node ...

Abstract

A method of forwarding data within a virtual network instance comprising a plurality of end nodes using a designated forwarding node, the method comprising maintaining a plurality of complete forwarding messages for all end nodes within the virtual network instance, receiving data sent to the virtual network instance A data packet of any end node in the virtual network instance, and forwarding the data packet based on the forwarding information, wherein the virtual network instance includes a plurality of end nodes, and the designated forwarding node is directly connected to some end nodes in the virtual network instance.

[0001] Related Applications Cross Application [0002] This application claims prior application priority to U.S. Provisional Patent Application No. 61 / 602,931, filed February 24, 2012, by Linda Dunbar et al., entitled "Delegated Forwarding and Address Resolution in Sharded 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 ph...
