Embodiment Construction

[0025] Specific embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0026] In the VRRP protocol, there are two important concepts: VRRP routers and virtual routers, master routers and backup routers. A VRRP router refers to a router running VRRP, which is a physical entity, and a virtual router refers to a logical concept created by the VRRP protocol. A group of VRRP routers work together to form a virtual router. The virtual router appears externally as a logical router with a unique fixed IP (Internet Protocol, Internet Protocol) address and MAC (Media Access Control, Media Access Control) address. Routers in the same VRRP group have two mutually exclusive roles: the master router and the backup router. There is only one router in the master role in a VRRP group, and there can be one or more routers in the backup role. . The VRRP protocol uses a selection strategy to select one from the router group as the master, ...

Abstract

The invention discloses one method and system for one city zone Ethernet reliability process, which comprises the following steps: establishing one virtual router redundant agreement set by two business control gates and separately establishing interface device and virtual router agreement gate connection through virtual special local net; according to the process results, determining virtual router main backup business control gate and establishes business control gate and interface for process.

Description

technical field [0001] The invention relates to a metropolitan Ethernet data reliability processing technology, in particular to a reliability processing method and system under the multi-service networking provided by the metro Ethernet. Background technique [0002] Ethernet (Ethernet) technology originates from LAN (Local Area Network), which is very simple and familiar to users, and Ethernet is a standard technology with good interoperability, extensive software and hardware support, and low cost; at the same time, it is also compatible with The media-independent bearer technology can transparently interface with different transmission media such as copper wire pairs, cables, and various optical fibers, avoiding the cost of rewiring. Therefore, the Ethernet networking technology has been greatly developed and is gradually becoming the bearer network of the MAN. [0003] However, for the operable carrier-class metro Ethernet, there are still many problems to be further r...
