[0003] However, in the prior art, when the VxLAN gateway forwards the VxLAN message to the next-hop device, it needs to modify the communication message in the load of the VxLAN message, and modify the source MAC in the communication message to the VxLAN gateway. MAC address, modify the destination MAC address to the MAC address of the next-hop device to forward the VxLAN message to the next-hop device, reducing the forwarding efficiency of the VxLAN message

Embodiment Construction

[0023] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0024] According to the provisions of the VxLAN protocol, a VxLAN message usually includes a payload and a message header, wherein the message header usually includes a 24-bit (bit) Virtual Extensible LAN Network Identifier (VxLAN Network Identifier, VNI), the IP address of the source NVE Information such as the IP address of the destination NVE i...

Abstract

The invention provides a packet forwarding method and a VxLAN gateway. The method comprises receiving a VxLAN packet, the load in which comprises a communication packet sent from a first VM to a second VM; determining a second VN1 of a subnetwork of next-hop equipment of the communication packet according to a first VN1 in the packet header of the VxLAn packet and the IP address of the second VM in the load; and packaging the communication packet according to the second VN1; and forwarding the packaged VxLAN packet to the next-hop equipment further through a tunnel corresponding to the second VN1. In this way, the condition that the forwarding of the VxLAN packet can be only realized after the VxLAN gateway corrects the communication packet in the load of the VxLAN is avoided, and the forwarding efficiency of the VxLAN packet is improved.

Description

technical field [0001] The invention relates to communication technology, in particular to a message forwarding method and a VxLAN gateway. Background technique [0002] A virtual extensible local area network (Virtual Extensible Local Area Network, VxLAN) technology is a technology used to extend network virtualization to obtain a sufficient number of virtual networks to satisfy users. [0003] However, in the prior art, when the VxLAN gateway forwards the VxLAN message to the next-hop device, it needs to modify the communication message in the load of the VxLAN message, and modify the source MAC in the communication message to the VxLAN gateway. MAC address, modify the destination MAC address to the MAC address of the next-hop device to forward the VxLAN packet to the next-hop device, reducing the forwarding efficiency of the VxLAN packet. Contents of the invention [0004] Embodiments of the present invention provide a packet forwarding method and a VxLAN gateway, whic...
