The embodiment of PTN ring circuit breaking protective systems described in the embodiment of the present invention is operationally：
When PTN nodes occur causing PTN node failures under external power-off, spread of voltage or other abnormal conditions, one
Aspect is that original is connected to the optical path auto-switch of the PTN nodes to the PTN ring circuit breaking protective system in parallel with the PTN nodes,
So that PTN nodes are not interrupted with the light path of ring other nodes, it is ensured that the looped network light path for going out to fail outside PTN nodes is normal；Separately
On the one hand be warning processing module by PTN webmasters northbound interface extract alarm signal of the PTN nodes not on looped network, with should
The alarm signal and the optical cable of whole access ring that two adjacent PTN nodes of PTN nodes disappear with the presence or absence of light path all occur different
The alarm combination such as normal alarm signal, and carry out a series of flow and judge computing：Even described warning processing module is extracted
Alarm signal of the current PTN nodes not on looped network is simultaneously extracted the light paths of the two PTN nodes adjacent with the current PTN nodes and disappeared
The alarm signal of mistake, and the alarm signal disappears after PTN ring circuit breaking protective systems lead the time of changing, then it represents that current PTN nodes
Optical bypass between external power-off and the two PTN nodes adjacent with the current PTN nodes, the warning processing module will be carried automatically
Show that " it is recommended that subtracting a little " operates, while triggering carries out subtracting data configuration a little to failure PTN nodes, so that the number of PTN looped networks
Can successfully it be forwarded on the looped network in addition to the PTN nodes that fail according to bag.By in terms of two above, it is possible to achieve recover except mistake
Imitate place access looped network and the business normal condition outside PTN nodes.
PTN nodes recover after external power supply, are on the one hand that live light path is automatic disconnected from the PTN ring in parallel with the PTN nodes
Electric protection system is switched on the PTN nodes, so that the light path of the PTN nodes is taken back in original PTN looped networks, it is ensured that whole
The light path of individual looped network is normal；On the other hand it is that the warning processing module is not existed by PTN webmasters northbound interface extraction PTN nodes
Port IP (agreement interconnected between network) address of alarm signal, adjacent PTN nodes on looped network is not in the announcement of the same network segment
All there is the alarm combination such as abnormal alarm signal in alert signal, and the optical cable of whole access ring, and carry out a series of flow
Judge after computing, judge that PTN nodes are once subtracted a little and external power supply is recovered, the warning processing module is pointed out automatically
" it is recommended that adding some points " operates, while the data configuration that triggering is added some points to the PTN nodes restored electricity, so that PTN looped networks
Packet can successfully be forwarded on whole PTN looped networks.Two aspect more than, realizes that recovery protection recovers PTN nodes and existed
The overall business recovery of interior loopful net.
When PTN nodes are not powered off, interrupted if now there are PTN node light paths, cause the de- pipe of PTN nodes, it is described
With PTN nodes, whether whether the two PTN nodes on looped network, adjacent with the PTN nodes give birth to optical bypass work to warning processing module
For basis for estimation, if current PTN nodes are produced not on looped network and between two PTN nodes adjacent with the current PTN nodes
The alarm signal of optical bypass is led to change in PTN ring circuit breaking protective systems to be existed always in period, then it represents that the light of current PTN nodes
Road has been interrupted, and now the warning processing module will be prompted to " it is recommended that starting Cable's Fault flow ", therefore of the present invention
The embodiment of PTN ring circuit breaking protective systems is being realized outside PTN power-off protection basic functions, moreover it is possible to effectively distinguish it is external power-off with
PTN nodes caused by Cable's Fault take off pipe phenomenon, are faster Network Search failure cause, and acceleration disturbance processing provides strong branch
Support.
PTN rings power-off protection method and system described in the embodiment of the present invention, it is possible to achieve physical light after the power-off of PTN nodes
Passage is jumped logical and ensures that other node traffics with ring are normal simultaneously, PTN nodes after restoring electricity fast quick-recovery loopful net it is original
The function of business, is effectively reduced because external power-off makes transmission access system be changed into chain structure from ring structure, i.e., with the other stations of ring
Point loses ring protection attribute, in addition, more can effectively prevent when same access ring is while there is the industry that other failures cause looped network
The situation that business is interrupted, greatly improves defeated internet security, lifts client perception.
Described above is the preferred embodiment of the present invention, it is noted that for those skilled in the art
For, on the premise of principle of the present invention is not departed from, some improvements and modifications can also be made, these improvements and modifications
