Embodiment Construction

[0052] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0053] Such as image 3 As shown, it is a schematic flowchart of the first embodiment of the method for processing VPLS network packets of the present invention. In this embodiment, the processing flow of the VPLS network message includes:

[0054] Step 101, the first UPE device receives the IP message sent by the first CE device, and replaces the source MAC address in the Ethernet message corresponding to the IP message with the MAC address of the first UPE device;

[0055] Step 102, the first UPE device forwards the replaced Ethernet packet according to the MAC forwarding table, wherein the IP packet obtains the destination MAC address by querying the pre-generated ARP table according to the destination IP address, and according to the destination MAC address for forwarding;

[0056] Step 103, after the second UPE...

Abstract

The invention relates to a treatment method for virtual private LAN service (VPLS) messages, comprising the following steps: after an internet protocol (IP) message is received by first UPE equipment, a source medial access control (MAC) address in a corresponding Ethernet message is replaced by an MAC address of the first UPE equipment, Ethernet message is forwarded according to an MAC forwarding table, after the Ethernet message is received by second UPE equipment, an Ethernet encapsulation is decapsulated, the corresponding target MAC address is inquired in an address resolution protocol (ARP) table, Ethernet encapsulation is newly carried out and the Ethernet message is forwarded. The invention also relates to a VPLC network message treatment system and UPE equipment; the source MAC address in the Ethernet message is replaced by adopting the MAC address of the UPE equipment at a forwarding end, and the Ethernet message is forwarded so as to ensure that the UPE equipment and NPE equipment used in the Ethernet message forwarding process can not learn the MAC address of non-local CE equipment, thereby the amount of MAC list items in the UPE and the NPE is reduced and the problem of low efficiency caused by the MAC-in-MAC encapsulation is avoided.

Description

technical field [0001] The invention relates to the field of network technology, in particular to a method, device and system for processing VPLS network messages. Background technique [0002] Today's IP networks have spread all over the world. How to use the existing IP networks to provide low-cost private networks for enterprises has gradually attracted the attention of major operators. Therefore, MPLS (Multiple Protocol Label Switch: Multi-Protocol Label Switching) VPN (Virtual Private Network: Virtual Private Network) technology came into being, which has the advantages of providing VPN services on IP networks, conveniently setting arbitrary rates, and simple configuration. [0003] There are two types of MPLS-based VPN services, namely L3 (Layer 3) MPLS VPN and L2 (Layer 2) MPLS VPN. L2 MPLS VPN includes VPLS (Virtual Private LAN Service: virtual private LAN service) and VPWS (Virtual Private Wire Service: virtual private wire service), among which VPWS is only suitab...
