Problems solved by technology

After VTEP receives the second message, it does not add Tag1 to the second message, which will also cause a message error
[0007] It can be seen that in the prior art, when the transmission mode of AC1 changes, it will cause packet errors, which will cause network service interruption

Embodiment Construction

[0066] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0067] The embodiment of the present application provides a packet processing method, which can be applied to VTEP and GW devices in VXLAN.

[0068] see figure 1 application scenarios, the message processing method of this application can be applied to figure 1 VTEP in. When receiving a modification instruction for the access mode of AC1, the VTEP may determine the VM1 corresponding to AC1, where the modification instruction carries the identifier of the target access mode. VTEP ...

Abstract

A message processing method and apparatus. The method is applied to a VTEP in a VXLAN. The method comprises: when receiving information which indicates that an access mode of a first AC is changed, determine a first VM corresponding to the first AC from recorded corresponding relationships of ACs and VMs, generate an update prompt message according to an identifier of the first VM, an identifier of a target access mode, and a preset update prompt mark, and send the update prompt message to a GW device; and the GW device updates an ARP table entry according to the update prompt message and forwards the received message according to the updated ARP table entry. On the basis of the processing, when a VTEP detects that an access mode of an AC is changed, a GW device may be prompted in time to update an ARP table entry, so that the GW device can forward a message according to the updated ARP table entry, thereby avoiding network service interruption.

Description

technical field [0001] The present application relates to the technical field of computer networks, in particular to a message processing method and device. Background technique [0002] VXLAN (Virtual eXtensible LAN, scalable virtual local area network) is a layer-2 VPN (Virtual Private Network, virtual private network) that adopts MAC (MediaAccess Control, media access control) in UDP (User Dategram Protocol, User Datagram Protocol) network technology. VXLAN can provide Layer 2 interconnection for dispersed physical sites based on the existing IP (Internet Protocol, Internet Protocol) network. [0003] Such as figure 1 As shown, the VXLAN networking includes: VTEP (VXLAN Tunnel End Point, VXLAN tunnel end point), GW (Gate Way, gateway) device, and multiple VMs (Virtual Machine, virtual machine). [0004] AC (Attachment Circuit, access circuit) 1 is an interface connected to VM1 on the VTEP. The VTEP may receive the first packet sent by VM1, and the first packet may car...
