Description
Technical field
The present invention relates to a kind of communication link network method, more particularly, relate to a kind of semipermanent connection that utilizes, from an end points with the method for data broadcasting to a plurality of end points.
Background technology
Semipermanent connection, promptly two end points remain the networking state, if there are abnormal conditions such as end points fault to take place, require when abnormal conditions are recovered, in time rebuild to network.The multicast of semipermanent connection, promptly from an end points by many semipermanent connections with data broadcasting to a plurality of end points.As two semipermanent connection: A-＞B (forward connection that the A point is ordered to B) and A-＞D (forward connection that the A point is ordered to D), for the A point, there are two semipermanent connections, be broadcast to B point and D point respectively thereby will enter the data that A orders.
For business such as signaling monitors, just need the such function of semipermanent multicast to realize.For example on switch, set up the semipermanent connection of a signaling A＜-B (two-way semipermanent connection of A and B), the A point is for connecting the relaying time slot of other equipment, import the signaling that A is ordered if want into from other equipment of C point monitoring, then need to set up an other semipermanent connection A-＞C, thereby be implemented in the function of C point by signaling monitor monitoring of equipment signaling.
Because dilatation needs, need a plurality of machine frames sometimes by cascade mode, expansion capacity.But, can cause the data of each machine frame inconsistent, thereby initiation problem owing to the reasons such as instability of communicating by letter between frame.For example, as shown in Figure 1, the forward direction of the terminal B of the terminal A of machine frame 1 and machine frame 2 networking A-＞B, pass through 3 optical fiber cascades between machine frame, select end points C point as middle time slot, time slot is at the time slot of machine frame 1, C in the middle of the C ' expression " the middle time slot of expression is at the time slot of machine frame 2.C ' and C " link to each other by optical fiber, by A-＞C ', C "-＞B, realize that the forward direction of A-＞B networks.
If machine frame 1 detects the terminal A fault, can disconnect the networking between A and the C ', then to machine frame 2 issuing messages, disconnect B point and C " between networking; but because the instability of communicating by letter between machine frame; if machine frame 2 is received the message that disconnects networking, just can not disconnect B and C " between networking.Like this, wait for that the terminal A fault eliminates when rebuilding, issue to machine frame 2 once more connect B and C " networking message (C "-＞B), will network owing to B point exists, and cause end points to converge, return failure, semipermanent connection can't be rebuild.
Under multimachine moulding spare, because professional needs such as signaling monitor often will be realized the multicast of semipermanent connection.When semipermanent connection reconstruction, because the exceptional conditions such as instability of communicating by letter between machine frame if in time do not discharge time slot, will cause end points to converge reconstruction failure.
For semipermanent connection, most important is exactly under any abnormal conditions, when the end points fault is eliminated, all will guarantee the reconstruction success of semipermanent connection in a short time.The semipermanent connection of common single frame, if there are abnormal conditions such as end points fault to take place, the whole networking of can dismantling when waiting pending fault to eliminate, is rebuild networking.
Semipermanent connection under the multimachine moulding spare if there are abnormal conditions to take place, also can when the end points fault is eliminated, be rebuild networking by the whole networking of dismantling.For example above-mentioned semipermanent connection A-＞B.The if there is no situation of multicast, for A point and B point, only may there be a semipermanent connection, when fault appears in the A point, when rebuilding networking,, the B point networks if existing, can be at machine frame 2 the networking complete removal of B point existence, rebuild then, thereby guarantee can not occur because end points converges the situation of reconstruction failure.
But for the situation of multicast, may there be the semipermanent connection of a lot of bars in the B point, and (this situation just can not guarantee not take place end points and converged by discharging whole networkings that B orders simply for B-＞D, B-＞E).Because if discharge whole networkings that B is ordered, the part networking that discharges other semipermanent connections that may be wrong causes other semipermanent connections to be broken.
Summary of the invention
The technical problem to be solved in the present invention is, a kind of method by semipermanent connection broadcast data is provided, overcome exist in the prior art after end points breaks down, because end points converges the defective that causes semipermanent connection reconstruction failure.

Description of drawings
The invention will be further described below in conjunction with drawings and Examples.
Fig. 1 is the schematic diagram of the semipermanent connection of 2 frames;
Fig. 2 is the schematic diagram of the semipermanent connection of 3 frames;
Fig. 3 is the schematic diagram of the semipermanent connection of another kind of 3 frames.
Embodiment
Among Fig. 1, pass through 3 optical fiber 102 cascades between machine frame 1 and the machine frame 2, end points C is the middle time slot of machine frame 1 and machine frame 2, wherein the middle time slot of C ' expression is at the time slot of machine frame 1; C " time slot is at the time slot of machine frame 2 in the middle of the expression, C ' and C " link to each other by optical fiber 102, the terminal B of the terminal A of machine frame 1 and machine frame 2 is by semipermanent A-＞C ' and the C of being connected "-＞B, realize that the forward direction of A-＞B networks.
If there is not the situation of semipermanent multicast, terminal B at most only exist one semipermanent, so directly all of end release B network and guarantee the correctness of semipermanent reconstruction.But because may there be many networkings (as B-＞D, B-＞E, not shown) in B point, so can not simply discharge all connections that B is ordered.If issuing message discharges C "-＞networking of B; by message authentication mechanism; if does not discharge successfully; then ceaselessly discharge; also can reach the purpose of release, if but a plurality of message all fail, must increase the message traffic of communicating by letter between machine frame; but also need to increase the affirmation message that release networks, increased the complexity of code.
If fault appears in the A of machine frame 1 point, do not discharge machine frame 2 networking (C "-＞B), when the A point failure recovered, the networking of only rebuilding machine frame 1 also was feasible.But so just can't reuse the code of common networking, because common networking, initial conditions is two end points (A and B) of terminal, and can not network according to the time slot of centre (C ' and C "); if only network; must realize the mechanism of semipermanent connection again, reduce reusable code at the A and the C ' of machine frame 1.
Therefore, in order to guarantee when the end points fault, the reconstruction success of semipermanent networking, before networking for the first time, a record block of a machine frame application at a corresponding semipermanent connection and its end points place writes down the information of this semipermanent connection and the networking information of the machine frame at this semipermanent end points place that is connected.
Record block is a memory block of opening up in the internal memory on each machine frame veneer, be used to preserve the networking information of a machine frame at semipermanent connection and its end points place, information and networking direction as semipermanent connection source endpoint, purpose end points, and the result that sets up of semipermanent connection (whether semipermanent networking is set up, if set up failure, the reason of record failure) information such as.
Distribute a unique call number for the record block of every semipermanent connection, be used to identify semipermanent link information, in the terminal point information with the corresponding semipermanent connection of record block call number inscription record piece place machine frame end points, the record block call number is one to one with semipermanent the connection, guarantees to index corresponding record block according to terminal point information.When two end points of semipermanent connection during at same machine frame, semipermanent connection is corresponding to a record block; When two end points of semipermanent connection during respectively at two machine frames, semipermanent connection is corresponding to two record blocks, and these two record blocks are kept at respectively in the internal memory of corresponding machine frame veneer.
When the record block call number networks by setting up for the first time, be handed down to each machine frame.When recovering semipermanent connection, index record block according to the record block call number, thereby find the information of relevant semipermanent connection.For example, write down semipermanent connection A-＞B and its networking information, and remain in the internal memory of machine frame 1 veneer at machine frame 1 at semipermanent connection A-＞B and record block of terminal A place machine frame 1 application; At semipermanent connection A-＞B and record block of terminal B place machine frame 2 applications, write down semipermanent connection A-＞B and its networking information, and remain in the internal memory of machine frame 2 veneers at machine frame 2.Give two record block allocation index numbers 11 of semipermanent connection A-＞B, and in the terminal point information with the corresponding semipermanent connection of these record block call number 11 inscription record pieces place machine frame end points (be A, C ', C ", B end points).At machine frame 1, according to record block call number 11, can find semipermanent connection A-＞C ', according to terminal A or C ', can find record block call number 11, thereby index the corresponding record piece; At machine frame 2,, can find semipermanent connection C according to record block call number 11 "-＞B, according to terminal B or C ", record block call number 11 can be found.Setting up for the first time semipermanent connection A-＞B, issue C to machine frame 2 "-＞during B networking message; simultaneously record block call number 11 is handed down to machine frame 2, machine frame 2 is with C like this "-＞information of B is stored in the record block of record block call number 11 correspondences, so that inquire about when rebuilding in the future.
If fault appears in the A point, when removing the networking of machine frame 1A-＞C ', issue to target endpoint B place machine frame 2 and to tear network information open, remove C "-＞networking of B.When the A point failure recovers, connect the networking of the A-＞C ' of machine frame 1, simultaneously to target endpoint B place machine frame 2 issue networking message (be C "-＞B), in message, carry record block call number 11.Machine frame 2 receive above-mentioned networking message (be C "-＞B) after; index corresponding record block according to record block call number 11 entrained in this message; the information according to this record block is carried out verification; if the networking that writes down in this record block (C "-＞B) be released the so directly semipermanent connection of reconstruction; Otherwise, elder generation's release networking (C "-＞B), and then rebuild networking.
If the user is when system configuration, deleted the information of semipermanent connection A-＞B, need issue to another machine frame of A-＞B correspondence by the machine frame 1 of semipermanent connection A-＞B correspondence or machine frame 2 and tear network information open, carry corresponding record piece call number in the message, remove A-＞C ' and C "-＞networking of B, delete simultaneously in machine frame 1 and the machine frame 2 corresponding to this semipermanent record block that is connected.If this message sends failure, will cause the networking of machine frame 1 and machine frame 2 not discharge.If again C ' and B point are networked later on, equally can be because end points converges and leads to the failure.Therefore, when machine frame 1 or machine frame 2 are received the networking message that C ' or B are ordered, if can cause end points to converge, just can find call number according to C ' and B is 11 record block, according to the information in the record block, carries out verification, if the semipermanent connection of this bar does not exist, to discharge networking, and the corresponding record block of deletion, the reusing of C ' and B point code thereby assurance networks in the future.
When the machine frame of deletion record piece was received networking message again, the record block call number of carrying according to this message is the application record piece again, and rebuilds networking.
Among Fig. 2, pass through 3 optical fiber 102 cascades between machine frame 1 and the machine frame 2, pass through 3 optical fiber 103 cascades between machine frame 1 and the machine frame 3, end points F is the middle time slot of machine frame 1 and machine frame 3, wherein in the middle of the F ' expression time slot at the time slot of machine frame 1, F " in the middle of the expression time slot at the time slot of machine frame 3, F ' and F " link to each other by optical fiber 103, the end points E of the terminal A of machine frame 1 and machine frame 3 is by semipermanent A-＞F ' and the F of being connected "-＞E, realize that the forward direction of A-＞E networks.
Among Fig. 2, there is other connection simultaneously in the A point, A-＞D (A point and D point coexist machine frame 1), A-＞E (A point and E point are respectively at machine frame 1 and machine frame 3), so also be these two semipermanent SEPARATE APPLICATION record blocks, and allocation index number is the link information that 12 record block is preserved A-＞D and corresponding machine frame thereof, and call number is the link information that 13 record block is preserved A-＞E and corresponding machine frame thereof.According to the information that A is ordered, set up chained list, can index the semipermanent link information (call number is the semipermanent link information of 11,12,13 record block correspondence) of all and A spot correlation according to the A point.
If A point failure, according to the A point, indexing call number at machine frame 1 is 11,12,13 record block, these record blocks are handled respectively: for call number is 11 record block (link information of record A-＞B and corresponding machine frame thereof), because C ' is a time slot between frame, so need to give 2 message of machine frame, handle semipermanent connection at machine frame 2, method is as mentioned above.
For call number is 12 record block (link information of record A-＞D and corresponding machine frame thereof), because D point be the end points of this machine frame, only needs to give this machine frame (machine frame 1) message, the networking of disconnection A-＞D.
For call number is 13 record block (link information of record A-＞E and corresponding machine frame thereof), and processing mode is identical with A-＞B.The F point is a time slot between selected frame, so at machine frame 1, is 13 record block according to call number, can find semipermanent connection A-＞F '; At machine frame 3, be 13 record block according to call number, can find semipermanent connection F "-＞E.If fault appears in the A point, when removing the networking of machine frame 1A-＞F ', issue to machine frame 3 and to tear network information open, carry record block call number 13 in the message, remove F "-＞networking of E.When the A point failure is eliminated, connect the networking of machine frame 1A-＞F ', simultaneously to machine frame 3 issue networking message (F "-＞E), in message, carry record block call number 13.Tear network information open if machine frame 3 has been received, and in time removed F "-＞networking of E, so when rebuilding networking, just do not have the situation that end points converges and take place.If but machine frame 3 is not received the message of removing networking, when networking, will return failure, therefore, when machine frame 3 is set up networking, to find the corresponding record piece according to record block call number 13, if the networking that writes down in the record block (F "-＞E) be not released, should discharge networking earlier, network again afterwards.
Among Fig. 3, pass through 3 optical fiber 102 cascades between machine frame 1 and the machine frame 2, pass through 3 optical fiber 204 cascades between machine frame 2 and the machine frame 4, end points I is the middle time slot of machine frame 2 and machine frame 4, wherein in the middle of the I ' expression time slot at the time slot of machine frame 2, I " in the middle of the expression time slot at the time slot of machine frame 4, I ' and I " link to each other by optical fiber 204, the end points H of the terminal B of machine frame 2 and machine frame 4 is by semipermanent B-＞I ' and the I of being connected "-＞H, realize that the forward direction of B-＞H networks.
If fault appears in the B point, handle equally according to the method described above.The networking situation is A-＞B, B-＞G, B-＞H, G point and the B point machine frame 2 that coexists, and H point and B point are respectively at machine frame 4 and machine frame 2.The record block call number of semipermanent connection is respectively 11,14,15, and call number is the link information that 14 record block is preserved B-＞G and corresponding machine frame thereof, and call number is the link information that 15 record block is preserved B-＞H and corresponding machine frame thereof.When fault appearred in the B point, according to the B dot information, indexing call number at machine frame 2 was 11,14,15 record block, and these record blocks are handled respectively.
For call number is 11 record block (link information of record A-＞B and corresponding machine frame thereof), is removing machine frame 2C "-＞during the networking of B, issue to machine frame 1 and to tear network information open, carry record block call number 11 in the message, remove the networking of A-＞C '.When the B point failure recovers, connect the C of machine frame 2 "-＞networking of B, issue networking message (A-＞C ') to machine frame 1 simultaneously, in message, carry record block call number 11.Tear network information open if machine frame 1 has been received, and in time removed the networking of A-＞C ', when rebuilding networking, just do not have the situation generation that end points converges so.If but machine frame 1 is not received the message of removing networking, when networking, will return failure, therefore, when machine frame 1 is rebuild networking, to search corresponding record block according to record block call number 11, if the networking that writes down in the record block (A-＞C ') be not released, should discharge networking earlier, network again afterwards.
For call number is 14 record block (link information of record B-＞G and corresponding machine frame thereof), because G point be the end points of this frame, only needs disconnect the networking of this machine frame to this frame (machine frame 2) message.
For call number is 15 record block (link information of record B-＞H and corresponding machine frame thereof), and processing mode is identical with A-＞B.The I point is a time slot between selected frame, so at machine frame 2, is 15 record block according to call number, can find semipermanent connection B-＞I '; At machine frame 4, be 15 record block according to call number, can find semipermanent connection I "-＞H.If fault appears in the B point, when removing the networking of machine frame 2B-＞I ',, carry record block call number 15 in the message, remove I to machine frame 4 issuing messages "-＞networking of H.When the B point failure is eliminated, connect the networking of the B-＞I ' of machine frame 2, simultaneously to machine frame 4 issue networking message (I "-＞H), in message, carry record block call number 15.Tear network information open if machine frame 4 has been received, and in time removed I "-＞networking of H, so when rebuilding networking, just do not have the situation that end points converges and take place.If but machine frame 4 is not received the message of removing networking, when networking, will return failure, therefore, when machine frame 4 is rebuild networking, to search corresponding record block according to record block call number 15, if the networking that writes down in the record block (I "-＞H) be not released, should discharge networking earlier, network again afterwards.
The method that the present invention proposes is not only applicable to two machine frames, can also smooth expansion to 3 multimachine frame situation more than the machine frame, and be applicable to various multimachine frame way to manages, as center machine frame centralization or the like.3 machine frame cascades for example, machine frame 0 is as Central switching frame, and machine frame 1 and machine frame 2 are professional frame, can give machine frame 1 and 2 message of machine frame by machine frame 0 so, control the situation of semipermanent connection reconstruction in each machine frame.
Adopt technical scheme of the present invention, can bring following beneficial effect:
1. index and the verification by record block overcome that prior art exists because end points converges Cause the defective of semipermanent connection reconstruction failure, guarantee that end points breaks down after, semipermanent The connection reconstruction success;
2. this scheme does not need to rewrite the processing that only need use common networking to the networking of various piece Get final product, thus greatly the increase of degree the dynamics of code reuse;
3. when discharging semipermanent connection, discharge networking, even release failure does not need to disappear yet The assurance of breath affirmation mechanism, but when again networking, according to the record block index in the message Check networking information, converge if can cause end points, can be according to the networking in the record block Information discharges networking, can not exert an influence to other semipermanent connections;
4. owing to the correct release that does not need to network between message authentication mechanism frame, therefore reduced Communicate by letter between frame.
This programme can be realized the telecommunication services such as signaling monitor under unit frame and multimachine moulding spare, both reached Arrive the purpose of dilatation, can realize flexibly again the business of various unit frames, just guaranteed semipermanent multicast Really rebuild and release.
