Embodiment Construction

[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments It is a part of embodiments of the present invention, but not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without creative efforts fall within the protection scope of the present invention.

[0056] figure 2 It is a flow chart of Embodiment 1 of the method for reclaiming a MAC address provided by the present invention. The method in this embodiment is suitable for the purpose of fast convergence when a device or a PW in the VPLS network fails, for example, when the PW between the UPE and the NPE, the UPE or the access circuit (AC) in...

Abstract

The embodiment of the invention provides a media access control MAC address recovery method and device. The method comprises the following steps: sending MAC address recycle information to other network devices when the detecting and obtaining of the network device occurs data transmission failure with the user device, the MAC address recycle information comprises initial identification, so as to enable other network devices to delete the MAC address corresponding to the initial identification in the MAC address table according to the mapping relation between the stored initial identification and the MAC address; the initial identification is used for the resource of the data flow transmitted by an unique identification among each network device. The media access control MAC address recovery method and device provided by the invention realize accurate deleting of MAC address, guarantee MAC addresses of the whole network being stable, and reduce the device load.

Description

technical field [0001] Embodiments of the present invention relate to communication technologies, and in particular to a method and device for recovering MAC addresses of media access control. Background technique [0002] Virtual Private LAN Service (VPLS) is a Layer 2 Virtual Private Network (VPN) technology based on Multi-Protocol Label Switching (MPLS) and Ethernet technology. VPLS can enable users to simultaneously access the network from multiple geographically dispersed sites and access each other, and make the connection effect between sites as if they are connected to a LAN. At present, VPLS is widely applied to metropolitan area network (Metropolitan Area Network, MAN) or wide area network (Wide Area Network, WAN). [0003] In VPLS, the Packet Switched Network (PSN) simulates a bridge device, and the service provider network edge device (Provider Edge, PE) performs Media Access Control (MAC) address learning, and the PE device learns the address according to MAC ...
