Abstract

The present invention discloses a home site backed method. Said method includes standby site monitoring ether net automatic protection system (EAPS) loop forming loop or not, if it is then standby site blocking one own port, and transmitting refreshing media control (MAC) address list message to other slave site. The present invention avoids broadcast storm occurrence in EAPS loop, greatly raising EAPS loop reliability.

Description

Technical field

[0001] The present invention relates to the Ethernet Automatic Protection System (EAPS) technology, in particular to a method for backing up a primary site on an EAPS ring and a backup site. Background technique

[0002] The EAPS ring is a ring network structure composed of a master site and multiple slave sites. figure 1 It is a schematic diagram of the structure of the EAPS ring. See figure 1 When the EAPS ring is working normally, the primary site blocks the spare physical port on its own side to ensure that the EAPS ring is a chain instead of a ring when transmitting business data, thereby avoiding unknown unicast and broadcast in the ring network The next loop broadcast occurs to avoid broadcast storms.

[0003] At present, in order to ensure that the EAPS ring can work normally when the primary site fails or recovers from the failure, a method of using the standby site to back up the primary site is proposed. figure 2 It is a flow chart of backup for the ...
