Overlay tunnel information exchange protocol

摘要

In one embodiment, a system includes logic adapted for receiving, at a first end point station, an information exchange packet from each end point station in a virtual network having a specified virtual network identifier (VNID) and logic adapted for processing each received information exchange packet to retrieve information about connections at each end point station in the virtual network having the specified VNID, wherein each end point station either terminates or originates a tunnel shared by the first end point station in an overlay network. In this way, the information may be used to respond to address resolution protocol (ARP) requests sent locally in lieu of flooding the ARP request. Other systems, methods, and computer program products are also presented regarding the overlay tunnel information exchange protocol, according to various embodiments.

主权项

1. A system, comprising:
a processor and logic integrated with and/or executable by the processor, the logic being configured to cause the processor to: receive, by the processor at a first end point station, information exchange packets from all end point stations in a virtual network having a specified virtual network identifier (VNID); and process each received information exchange packet to retrieve information about connections at each end point station in the virtual network having the specified VNID, wherein each end point station either terminates or originates a tunnel shared by the first end point station in an overlay network, and wherein each of the information exchange packets comprise a media access control (MAC) address for all member virtual machines (VMs) in the virtual network having the specified VNID connected to each end point station in the virtual network having the specified VNID.
