Embodiment Construction

[0105] Embodiments of the present application provide a packet processing method, device, and network system. Through the pre-negotiation between the provider edge (Provider Edge, PE) device and the user edge (Customer Edge, CE) device, it is determined that among the PE devices connected to the CE device, the PE device whose port status is active, and the port status is Inactive PE equipment. And based on the pre-negotiated PE device whose port status is inactive, when the link transmitting the message fails, the link can be quickly restored to ensure the reliability of the VXLAN network.

[0106] The packet processing method disclosed in the embodiment of the present application will be described in detail through the following specific examples.

[0107] Such as figure 1 As shown, it is a schematic structural diagram of a network system disclosed in the embodiment of the present application. The network system includes a first PE device 11 , a second PE device 12 , a thi...

Abstract

The present application provides a message processing method, device and network system. The network system includes a first PE device, a second PE device, a third PE device and a CE device. The state of the port connecting the first PE device to the CE device is an active state, and the state of the port connecting the second PE device to the CE device is an inactive state, and the method includes switching the state of the port connecting the first PE device to the CE device from an active state In the inactive state, the first PE device sends a MAC entry update message to the third PE device, triggering the third PE device to delete the first MAC entry whose message forwarding address is the first PE device, and learn to generate a message The forwarding destination address is the second MAC entry of the second PE device, and packet forwarding is performed based on the second MAC entry. After a fault occurs, the link can be quickly restored for packet forwarding, ensuring the reliability of the VXLAN network.

Description

technical field [0001] The present invention relates to the technical field of communication, in particular, to a message processing method, equipment and network system. Background technique [0002] Virtual extensible local area network (Virtual eXtensible Local Area Network, VXLAN) is an IP-based network, adopts MAC-in-UDP packet encapsulation mode, and encapsulates layer-2 packets with layer-3 protocols. Specifically, an Ethernet frame based on a Media Access Control (Media Access Control, MAC) protocol is encapsulated in a User Datagram Protocol (User Datagram Protocol, UDP) message. The VXLAN technology uses a VXLAN Network Identifier (VXLANNetwork Identifier, VNI) to identify a VXLAN network segment, which is used to distinguish different VXLAN network segments, and its length is 24 bits. [0003] VXLAN networks generally use the all-active gateway technology to increase network reliability. An all-active gateway means that multiple VXLAN gateway devices form a load...
