Problems solved by technology

[0005] In the process of realizing the present invention, the inventor found that the prior art has at least the following problems: since the NPE is the centralized processing point of the business, that is, all users of the Metro-E network will enter the three-layer network here, therefore, the NPE needs to save the Metro The ARP entries of all network users within the -E range cause the number of ARP entries to become the bottleneck of the application, the network scalability is poor, and the network scale is limited

Embodiment 1

[0028]FIG. 1 is a flow chart of Embodiment 1 of the method for processing data in a metro Ethernet access network according to the present invention, and FIG. 2 is a schematic diagram of the networking in FIG. 1 . It is assumed that the VLPS transmission network between NPE equipment 10 and UPE equipment 1 synthesized by PE-AGG 12 and SR11 is a VLPS transmission network, in which 40 is a data transmission path, which runs through user terminals, CE 30, UPE 1 and NPE 10, and NPE 10 is preset There is an interface, the data received from this interface, NPE 10 will encapsulate a preset MAC address, correspondingly, this preset MAC address is saved in UPE 1, so as to perform query ARP table entry according to this MAC address operation. After receiving the data sent by the network side, the NPE 10 specifically performs the following operations:

[0029] Step 101: After the NPE receives the network-side service data from the set interface, it directly encapsulates the preset MAC ...

Embodiment 2

[0039] FIG. 3 is a flow chart of Embodiment 2 of the method for sending service data according to the present invention, and FIG. 4 is a schematic diagram of networking in FIG. 3 . Assuming that there is an Ethernet network between the NPE and the UPE, a specific interface is preset in the VLAN sub-interface of the NPE to receive data, and a preset VLAN is assigned to the data received by the interface. Correspondingly, the UPE also stores the preset specified VLAN. Metro-E performs the following operations after receiving data from the network side:

[0040] Step 201: After the NPE receives the network-side service data from the set port, it arbitrarily encapsulates a MAC address to the received network-side service data. Since the VLAN is preset between the NPE and the UPE, the MAC address does not need to be the destination MAC The address or specific MAC address is just to make the network side business data meet the sending conditions, ensure that the network side busine...

Abstract

The present invention relates to an operator edge equipment, a Metro Ethernet access network, and the data processing method. The method comprises: a network side data is received from a set interface; a UPE enquiries an ARP table, to obtain a destination MAC address; the data is packaged by the destination MAC address for sending. The equipment comprises a data receiving module, a data sending module, a reception requesting module, a table establishment module, a judging module, an enquiry module and a packaging module; the metro Ethernet access network comprises a network side-oriented operator edge equipment and a user side-oriented operator edge equipment, wherein a network side data receiving module, an interface judging module and a network side data sending module are arranged on the network side-oriented operator edge equipment. The proposal avoids the focus conservation of the ARP table of the Metro Ethernet total network users, and improves the network expandability and the handling capacity of the NPE.

Description

technical field [0001] The invention relates to a virtual private local area network technology, in particular to a data processing method of a metropolitan Ethernet access network, an operator edge device facing a user side, and a metropolitan ether access network. Background technique [0002] Virtual private local area network (LAN) service (Virtual Private LAN Services, VPLS) is a two-layer virtual private network (VPN) technology, and its function is a virtual LAN switch. By providing functions similar to LAN services on a multi-protocol label switching (Multi protocol Label Switching, MPLS) network, users can simultaneously access the network from multiple geographically dispersed points and access each other, as if these points are directly connected to Same on LAN. As shown in Figure 6, the interface where the user edge equipment (Custom Edge, CE) 20 is located joins the VPLS virtual switching instance (Virtual SwitchInstance, VSI) 50, and the operator edge equipmen...
