Problems solved by technology

[0004] The router between the first router and the second router can forward the IPsec-ESP packet, but the router on the transmission path between the first router and the second router cannot perceive the IPsec-ESP packet included in the VXLAN packet. VXLAN-related information, such as VXLAN network identifier (English full name: VXLAN Network Identifier, English abbreviation: VNI), and thus cannot perform load sharing and other business processing

Abstract

The invention provides a method, a device and a system for processing a VXLAN (Virtual Extensible Local Area Network) message, which are helpful for routers among different data centers to obtain VNIs (VXLAN Network Identifier). The method comprises the following steps that a first router receives a VXLAN message which is sent by a VTEP (Virtual Tunnel End Point), wherein the VXLAN message comprises a VNI; the first router obtains an encapsulated message according to the VXLAN message, wherein the encapsulated message is obtained after carrying out IPsec-ESP (Internet Protocol Security-Encapsulating Security Payload) encapsulation on the VXLAN message, the encapsulated message comprises an IP (Internet Protocol) header, the VNI, an ESP header and the encrypted VXLAN message, and the VNI is encapsulated between the IP header and the ESP header; and the first router sends the encapsulated message to a second router.

Description

technical field [0001] The present invention relates to communication technology, in particular to a method, device and system for processing Virtual Extensible Local Area Network (English full name: Virtual Extensible Local Area Network, English abbreviation: VXLAN) messages. Background technique [0002] VXLAN can be applied inside the data center, so that virtual machines can migrate within the interconnected three-tier network without changing the Internet Protocol (English full name: Internet Protocol, English abbreviation: IP) address and media access control (English full name : Media Access Control, English abbreviation: MAC) address, to ensure business continuity. Internet Protocol Security (English full name: Internet Protocol Security, English abbreviation: IPSec) protocol can ensure confidential and secure communication on the IP network by using encrypted security services. Encapsulating Security Payload (English full name: Encapsulating Security Payload, Engli...
