Problems solved by technology

However, when the main site is working normally, the standby port on one side is blocked, and the transmission of business data will not pass through the main site. Therefore, even if the main site fails, the transmission of business data will not be affected. There is no need for the standby site to send the failure notification message of the primary site and refresh the MAC address table with other sites. Therefore, the business process is increased needlessly and the difficulty of service implementation is increased.

Embodiment Construction

[0043]The core idea of ​​the present invention is: the standby site monitors whether the EAPS ring of the automatic Ethernet protection system forms a ring, if so, the standby site blocks one of its own ports and sends the message to refresh the media access control MAC address table to other slave sites .

[0044] Wherein, the backup site may perform the process of monitoring whether the EAPS ring forms a ring after detecting the failure of the primary site.

[0045] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0046] image 3 It is a flowchart of backing up the main site when the ring network changes in the embodiment of the present invention. See figure 1 with image 3 In the present invention, when the ring network changes, that is, when the slave sites or links other than the primary ...

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 ...
