Embodiment 1

[0074] Figure 5 A message processing method provided by an embodiment of the present invention is applied to a server, and the server can be image 3 In the device using VNF technology, the server can include: at least one forwarding plane VM, each forwarding plane VM can be pre-configured with a loopback IP address, inline port IP address and external port IP address, the inline port is the server forwarding The interface for transmitting packets between VMs on the forwarding plane. The external interface can be the interface for transmitting packets between the forwarding plane VM in the server and the remote device (PE device). Each VM on the forwarding plane can be connected to at least one user, and these Users can as image 3 As shown, it is directly hung under the CE device, and the CE device is connected to the forwarding plane VM through the AC link. One VSI can be set on each forwarding plane VM, and all VSIs on the forwarding plane VM can belong to the same VPLS n...

Abstract

The invention discloses a virtual private LAN service (VPLS) message processing method and a VPLS message processing device, and relates to the field of network technologies, for solving the problems that in existing VPLS networking adopting a virtual network function (VNF) technology, VPLS forwarding traffic detours and traffic forwarding performance is poor due to the fact that multiple virtual machines (VM) share one virtual switching instance (VSI). According to the method, one VSI is arranged on each forwarding plane VM; and the method comprises the steps of receiving a message comprising a MAC address of a first user and a MAC address of a second user sent by the first user by using the first forwarding plane VM, querying a MAC forwarding table, acquiring a first interface corresponding to the MAC address of the second user in the MAC forwarding table, encapsulating a first private network label and a first public network tunnel label in the message, encapsulating a MAC address of the first interface and a MAC address of an interface of a first opposite terminal in the encapsulated message to form a VPLS message, and sending the encapsulated VPLS message out via the first interface.

Description

technical field [0001] The present invention relates to the field of network technology, in particular to a virtual private LAN service (Virtual Private LAN Service, VPLS) message processing method and equipment. Background technique [0002] VPLS is developed on the basis of traditional multi-protocol label switching (Multi-Protocol Label Switch, MPLS) L2VPN (Layer2Virtual Private Network, Layer 2 virtual private network) scheme. Pseudo Wire (PW) is established and maintained between Provider Edge (PE) devices, and Layer 2 protocol frames are encapsulated and then transmitted and exchanged on PW, so that multiple Local Area Networks (Local Area Networks) within a wide area , LAN) is integrated into a network at the data link level to provide users with virtual Ethernet (Ethernet) services. [0003] figure 1 It is a schematic diagram of the existing VPLS network, such as figure 1 As shown, the VPLS network can include: multiple PE devices and customer edge (Customer Edge,...
