[0005] It can be seen from the above description that the current proposed method to ensure the normal operation of the EAPS ring is for the failure and recovery of the secondary sites and links on the EAPS ring except the primary site, but not for the primary site. The processing method for the change of the working status, that is to say, there is no processing method for the failure of the primary site, that is, the processing method after the working status changes from normal to faulty, and there is no recovery for the primary site failure, that is, the working status changes from faulty to faulty. The processing method after the normal state. In this way, when the working status of the master site changes, the master site cannot notify each slave site to refresh the MAC address table, and each slave site cannot refresh the MAC address table according to the actual site connectivity of the EAPS ring. Therefore, the transmission of subsequent business data cannot be guaranteed, and the normal operation of the EAPS ring cannot be guaranteed

Embodiment Construction
[0037] According to the working principle of the EAPS ring, the key factors to ensure the normal operation of the EAPS ring include: each station on the EAPS ring must be connected, and each station must perform transmission according to the correct MAC address table. In the initial normal state, the standby physical port on the primary site side is blocked, so that regardless of whether the primary site fails, each secondary site is connected. It can be seen that when the working status of the primary site changes, the primary site After a failure or recovery, the key factor to ensure the normal operation of the EAPS ring is to make each slave station on the EAPS ring refresh the MAC address table in time according to the actual station connection status of the EAPS ring, so that the subsequent transmission process can be performed according to the correct MAC address table .
[0038] For above-mentioned characteristics, the present invention proposes a kind of method that gu...

The method includes following steps: standby station is set in slave station on EAPS rings; when the standby station finds the working state of main station is changed, it informs each station on EAPS rings to refresh MAC address table; the standby station and other stations refreshes MAC address table.
Description
technical field [0001] The invention relates to an Ethernet automatic protection system (EAPS) technology, in particular to a method for ensuring the normal operation of an EAPS ring when the working state of a main site changes. Background technique [0002] The EAPS ring is a ring network structure composed of a master site and multiple slave sites. There are business data and control messages transmitted in the EAPS ring. In the initial normal state, for business data, the primary site blocks the standby physical port on its side to ensure that the EAPS ring is a chain rather than a ring when transmitting business data, thereby avoiding unknown unicast and broadcast The cyclic broadcast under the ring network occurs; for the control message, the master site does not need to block the spare physical port on its own side, that is to say, when transmitting the control message, the EAPS ring is a ring, so that the master site from the physical port on one side The sent cont...
