Embodiment Construction

[0035] In the following, specific examples will be used to describe in detail respectively.

[0036] In the embodiment of the present application, UP indicates that the port is open or available, that is, the port is allowed to send and receive data packets; DOWN indicates that the port is closed or unavailable, that is, the port is not allowed to send and receive data packets.

[0037] figure 1 It is a schematic diagram of an EVPN-VPWS network structure according to an embodiment of this application. Such as figure 1 As shown, the EVPN-VPWS network includes a first PE device, a second PE device, and a third PE device. A first point-to-point (point-to-point, P2P) virtual extended local area network (virtual extensible local area network, VXLAN) tunnel is established between the first PE device and the third PE device, and the second PE device A second P2PVXLAN tunnel is established with the third PE device. Wherein, the P2P VXLAN tunnel is generally a bidirectional tunnel,...

Abstract

The invention discloses a method, equipment and system for processing a message. The method comprises the following steps: first PE equipment receives a first VXLAN message through a first P2P VXLAN tunnel between the first PE equipment and third PE equipment; CE equipment is dual-homed to the first PE equipment and the second PE equipment through a first Ethernet link and a second Ethernet link;when the first PE equipment determines that the first Ethernet link is in fault, the first PE equipment forwards the first VXLAN message to the second PE equipment through a third P2P VXLN tunnel to the second PE equipment from the first PE equipment, wherein the first Ethernet link connected with the first PE equipment and the link composed of the third P2P VXLAN tunnel and the second Ethernet link are in a active/standby relation. Therefore, the transient traffic detouring is realized, and the packet loss produced in the transmission process of the data traffic can be reduced.

Description

technical field [0001] The present application relates to the technical field of communications, and in particular to a method, device and system for processing messages. Background technique [0002] Ethernet virtual private network (ethernet virtual private network, EVPN) is a layer 2 virtual private network (virtual private network, VPN) technology. EVPN connects customer sites in different regions through a cross-Internet Protocol (Internet Protocol, IP) / multiprotocol label switching (multiprotocol label switching, MPLS) bearer network, which means that these customer sites are located in the same local area network (local area network, LAN). [0003] A virtual private wire service (virtual private wire service, VPWS) may also be called a virtual leased line (virtual leased line, VLL). VPWS refers to imitating asynchronous transfer mode (asynchronous transfer mode, ATM), frame relay (frame relay, FR), Ethernet (Ethernet), low-speed time division multiplexing as realist...
