Step 306, according to different Linktypes, real-time monitoring annular Link State, including link break-make situation, node
Time delay value, delay variation between node etc.；
Whether step 307, real-time monitoring Link State change, if Link State does not change, continue to walk
Rapid 306；If Link State there occurs change, execution step 308 and step 309；
Step 308, judge whether link meets switching condition, if being unsatisfactory for switching condition, continue executing with step
306；If link meets switching condition, execution step 309；
Step 309, link-state change situation or link switching situation are recorded；
If step 310, link meet link switching condition, link switching is carried out；
It is ring network under link normal operation, when there is link disconnection or too big time delay value, Jiu Huibian
Into Chain Network, it is ensured that the normal operation of business；
Step 311, switching whether success is judged, if handover success, then continue step 312；If it fails, turning to step
Rapid 310, continue to attempt to 3 switchings；
After step 312, link switch, the running status of link changes, and at this moment system sends out broadcast packet to net
Element device, network element just reports up link running state information, for example the time delay between loop network link direction, link nodes
Value, delay variation etc.；Circulate execution step 306 and arrive step 312；
Step 313, the link running state information to recording in step 309 are processed, and the ruuning situation of link is entered
Row analysis, so as to grasp the variation tendency of link ruuning situation；
Step 314, data derivation is carried out according to the different demands of user, for example, derived according to the time, according to link
Type is derived etc.；Terminate.
If there are multiple ring networks in base station, simultaneously link protection can be carried out using said method.
