Abstract
The invention dissolves a hot backup device in multipurpose segment protective switch technology for communication system, which realizes complete, high-effect and reliable switch anytime to primary and standby protocol entities on whatever multipurpose segment protective state. This invention sets adapting layer modules in two protocol entities for treatment according to state.
Description
Technical field
The present invention relates to the multiplex section protection exchanging technology of communication system, particularly the Hot Spare of multiplex section protection exchanging is realized technology.
Background technology
Synchronous digital hierarchy (Synchronous Digital Hierarchy is called for short " SDH ") technology can obtain develop rapidly and extensive use, and can be adopted by optical transmission system, and one of them important reasons is exactly its self-healed protection function.And multiplex section protection (MultiplexSeetion Protection is called for short " MSP ") is a kind of salvo efficiently in various networking protections, also is one of most important salvo in the current optical transmission system.
(the International Telecommunication Union-Telecommunication Standardization Sector of international telecommunication union telecommunication standardization; be called for short " ITU-T ") in G.841 it advise; clearly defined the multiplex section protection exchanging agreement APS (AutoProtection Switching is called for short " APS ") of transmission equipment.The agreement regulation; multiplex section protection exchanging is realized by K1 and the transmission of K2 byte; wherein preceding 4 bit tables of K1 byte are levied bridge request codes; back 4 bit tables are levied the destination node identification code; and preceding 4 bit tables of K2 byte are levied the source node identification code; the 5th bit table is levied short path or long path, and back 3 bit tables are levied the state of multiplex section protection exchanging.
Optical transmission system is guaranteed professional can switch and not be interrupted by protection under equipment or fibre circuit abnormal conditions by multiplex section protection exchanging.The reliability of multiplex section protection exchanging directly influences client's business, is the performance index that the client is concerned about most.In communication system, particularly in the optical transmission system, the transmission rate of each optical fiber can reach 40Gbps, in case owing to the multiplex section protection exchanging failure causes interrupting, its data degradation amount is huge, and the economic benefit of bringing thus loss can't remedy.
As seen, guarantee that it will be a very crucial technology that the multiplex section agreement continues normal operation.In the practical application, the multiplex section agreement generally operates on the master control borad of transmission system, also may operate on cross board or the wiring board, the generation that the operation of various plates all resets in the hardware fault that causes for some reason and soft or hard unavoidably, therefore in order to guarantee normally running without interruption of important protocol, generally adopt the method for agreement Hot Spare.That is, adopt and corresponding mainly to carry out backup to agreement with veneer and standby board, multiplex section protection moves with veneer by leading under the normal condition; occur unusually with veneer when main; then take over operation by standby board, be not interrupted with guarantee agreement, business obtains reliable protection.
In general; for make agreement operate in active and standby be subjected to when switching influence minimum; synchronous operation with main with the same the multiplex section protection protocol of veneer on standby board; when when the master was lost efficacy with veneer, the agreement on the standby board is taken over the master and is carried out multiplex section protection with the agreement on the veneer.Active and standby protocol synchronization with veneer makes active and standby switching seamlessly finish smoothly.Yet; in the Hot Spare of multiplex section protection exchanging; it is no problem carrying out active and standby switching when multiplex section is in Idle state; when but multiplex section protection exchanging is carrying out; active and standby switching just may produce with multiplex section protection exchanging and conflict; cause the multiplex section protection protocol to carry out wrong operation, the traffic affecting protection.Just need carry out masterslave switchover if simultaneously in the software of main veneer is in the process of warm reset, multiplex section protection exchanging takes place; do not carry out masterslave switchover if there is the protection of multiplex section to switch, prevent that frequent masterslave switchover from influencing the reliability service of multiplex section agreement with regard to not needing.
Therefore; for the operate as normal incessantly of the multiplex section protection protocol on the active and standby veneer; just must there be effective mechanism to guarantee that network element is under various multiplex section rearrangement states; active and standby multiplex section agreement is switched can be successful; and service impact is reached minimum, promptly realize the active and standby protocol entity seamless switching under the state of various multiplex sections.
Because the active and standby veneer of using switches in the multiplex section protection exchanging process if desired, then must keep the consistency of both sides' state and configuration etc.The coordination that utilizes webmaster to carry out active and standby agreement switching is a kind of scheme, because webmaster can utilize digital communication passage (Digtal CommunicationChannel by Gateway Network Element, be called for short " DCC ") communicating by letter keeps communicating by letter with all network elements, and can collect the state and the configuration information of all network elements, thereby keep the network element state configuration consistency.But this scheme depends on the reliability of DCC communication and webmaster, and the time of switching is long, and complexity is higher, is a kind of centralized processing mode, and efficient is low.
Another kind of technical scheme is to utilize the masterslave switchover of other veneer control multiplex section agreements of not moving the multiplex section agreement, and the veneer of control masterslave switchover is responsible for specially with active and standby and is communicated with veneer, keeps both sides' state consistency.This scheme must make the veneer of control masterslave switchover have the configuration information of multiplex section also to want to detect in real time the inefficacy of mainboard.Not only owing to many control with a veneer makes hardware cost increase, and control veneer and active and standby realization with the communication control processor between the veneer has also increased the complexity of switching realization greatly.In addition, this scheme also can reduce system reliability, because the veneer of control masterslave switchover also can lose efficacy, causes the possibility of the multiplex section protection protocol failure higher.
In actual applications, there is following problem in such scheme: masterslave switchover is realized complicated, and with high costs, efficient is low, and reliability is low.
Cause the main cause of this situation to be, adopt webmaster to carry out the carrying out of centralized control masterslave switchover, perhaps adopt extra veneer and special communication protocol to control the carrying out of masterslave switchover.
Summary of the invention

In step 201, being equipped with adaptation layer module configuration state attribute is unknown state, sends order to mainboard then, asks the synchronous of multiplexing segment status attribute, promptly asks synch command.Because active and standby both sides link to each other by adaptation layer, therefore this order promptly is sent to main adaptation layer module.
Then enter in the step 202, main adaptation layer module is transmitted to the master agreement controller with this order after receiving the request synch command.
Then enter in the step 203, the master agreement controller if agreement is not in the start-up course, just obtains controller data after receiving the request synch command, such as multiplexing segment status, configuration parameter etc., and is encapsulated in the sync response order, returns to main adaptation layer module.
Then enter in the step 204, send to slave board after with the sync response order, promptly receive by being equipped with adaptation layer module by main adaptation layer module.
Then enter in the step 205, after adaptation layer module was received the sync response order fully, it was that agreement starts that status attribute is set, and transmitted the sync response order simultaneously and gave protocol controller fully.
In step 206, by being equipped with protocol controller according to the sync response order of receiving, resolve controlled device data, and be set to synchronously in the slave board at last, synchronizing process is finished.
In one embodiment of the invention, if in any one step among the step 201-205, for a certain reason, asynchronous in start-up course such as communication between plates failure, agreement, and cause synchronizing process to be interrupted, then being equipped with adaptation layer module, status attribute will be set is unknown state, and agreement inner be initial agreement halted state just.In the described below various synchronizing processes,, also carry out same processing if interrupt.
Same, in one embodiment of the invention,, can be described below in the operating timing cycle synchronizing process of agreement:
It is one subsynchronous that mainboard can be initiated in per two minutes, and promptly every two minutes, main adaptation layer module promptly transmits the request synch command and gives the master agreement controller; Then, the master agreement controller if agreement is not in the start-up course, is just obtained controller data after receiving orders, return the sync response order, is transmitted to slave board by main adaptation layer module; Be equipped with adaptation layer module and receive the sync response order, the configuration state variable is that agreement starts, and is transmitted to protocol controller fully; Order is provided with controller data according to sync response by being equipped with protocol controller, and synchronizing process can be finished.
Switch in active and standby agreement and also to carry out same synchronizing process when finishing.Concerning the multiplex section agreement, the condition that active and standby switching takes place is a lot, such as issuing active and standby protocol entity switching command by hand, issue the switching command of protocol entity place veneer and its slave board by hand, master agreement entity place veneer hard reset, the plug of master agreement entity place veneer, rob the masterslave switchover of the protocol entity that success triggers owing to preparation, the hardware fault of protocol entity place veneer etc., after causing active and standby switching, active and standby transposition, new mainboard (being original slave board) will be received the mainboard off-line order that adaptation layer module transmits, if this stylish slave board is in the reversed process, so new mainboard restarts agreement; Otherwise promptly from new slave board (being original mainboard) isochronous controller data, synchronizing process is as follows for new mainboard:
At first, the protocol controller of new mainboard returns to main adaptation layer module request synch command after receiving the order of mainboard off-line, transmits this request synch command by main adaptation layer module and gives new slave board; New slave board promptly is transmitted to protocol controller fully after receiving this order; Be equipped with protocol controller after receiving the request synch command,, just obtain controller data, return the sync response order and give adaptation layer module fully, be transmitted to new mainboard by being equipped with adaptation layer module if agreement is not in the start-up course; Main adaptation layer module is transmitted to the master agreement controller after receiving the sync response order, by the master agreement controller controller data is set synchronously.
In addition, in mainboard warm reset process, slave board will be in preparation and rob state, if in this process, have ready conditions to trigger and switch or switch recovery, it is disconnected such as optical fiber takes place, optical fiber recovers, error code, error code recovers, issuing the outside switches, issue the outside and switch situations such as removing, to cause slave board to send actions such as K byte or lower page, and satisfy the condition of switching, be that slave board is when working properly, slave board promptly prepares and robs successfully so, become mainboard, new mainboard (being original slave board) will be received the mainboard off-line order that adaptation layer module transmits, and the protocol controller of the mainboard that this is stylish will discharge the current page of switching, initialization controller data then, and restart agreement.
Though by reference some preferred embodiment of the present invention, the present invention is illustrated and describes, but those of ordinary skill in the art should be understood that, can do various changes to it in the form and details, and the spirit and scope of the present invention that do not depart from appended claims and limited.
