Description
Technical field
The present invention relates to communication technical field, particularly a kind of method and apparatus that path status is set.
Background technology
SCTP (Stream Control Transmission Protocol, SCTP) is a kind of reliable host-host protocol, and it provides stable, orderly data delivery service between two end points.When respectively a plurality of transport address being arranged in two SCTP endpoint, just there are many transmission paths in the coupling between these two SCTP endpoint.Under the normal condition, with a paths transport service wherein, this paths is called primary path, and remaining path is a backup path.For example, the port numbers of terminal A is 100, and two transport address IP1 and IP2 are arranged, the port numbers of terminal B is 100, two transport address IP3 and IP4 are arranged, and then the coupling between terminal A and the terminal B is { [IP1, IP2:100]: [IP3, IP4:100] }, have 4 transmission paths, IP1-＞IP3, IP1-＞IP4, IP2-＞IP3 and IP2-＞IP4, wherein, IP1-＞IP3 is a primary path, and all the other 3 is backup path.
The handover mechanism of existing SCTP transmission path is as follows: for every paths is provided with an error counter (EC, ErrorCounter), when user data transmits on this paths, log-on data timer (T3-rtx) timing, if data timer expiry and not receiving when the opposite end is confirmed, think and user data loss error counter is added 1.When the value of error counter adds up when reaching the maximum error thresholds in path, then the purpose transport address of this paths correspondence is changed to unactivated state, this paths is unavailable.When if user data of no use is transmitted on this paths, can utilize heartbeat message to detect path status.When the data of receiving the opposite end on this paths, affirmation or heartbeat are responded, think that then this paths can use, with the error counter zero clearing, and the purpose transport address of this paths is changed to state of activation.When primary path is state of activation, use primary path transmission data; When the primary path state is unactivated state, use the backup path transmission data that are in state of activation; As long as primary path returns to state of activation, then switch back to primary path transmission data immediately.
After above-mentioned prior art is analyzed, the inventor finds: (the Quality of Service of the QoS on this paths, when service quality) poor, factor causes retransmitting because packet loss, time delay be excessive on the path etc. though a lot of messages are arranged, but owing to retransmit successfully, switch in the actual path of can't triggering, have only when primary path interrupts fully, just select the backup path transport service, thereby cause when the QoS of primary path reduces, transmission bandwidth is promptly wasted in the re-transmission that message is a large amount of, wastes system processing power again.

Embodiment
For making the purpose, technical solutions and advantages of the present invention clearer, embodiment of the present invention is described further in detail below in conjunction with accompanying drawing.
Referring to Fig. 1, the embodiment of the invention provides a kind of method that path status is set, and comprising:
101: the error counter that obtains the path is the number of times of change in count at the appointed time; Wherein, the stipulated time can be set to different values as required, and as 3 minutes or 5 minutes or the like, described change in count does not comprise the variation of error counter zero clearing;
102: whether judge the number of times obtain more than or equal to default change frequency threshold value, if, think that then the QoS in this path is not up to standard, current when being state of activation in this path, it is deactivation status that this path is set, flow process can finish;
Wherein, the change frequency threshold value can be set to different values as required, as 5 times or 8 times or the like.
In the present embodiment, the change in count of error counter is divided into two kinds, the variation of zero clearing and the variation of non-zero clearing, and the variation of this non-zero clearing promptly is meant the variation that adds up.Wherein, when the error counter zero clearing, show on this paths and can receive message, think that this paths can use; And when the change in count of error counter is not zero clearing, as add 1, show and on this paths, lose message that message needs to retransmit.Therefore the change in count number of times that does not comprise zero clearing in the change in count of error counter, reflected the number of times that message retransmits on this path, reflected the QoS index on this path indirectly,, surpassed default change frequency threshold value if this change frequency is bigger, the number of times that then shows the message re-transmission is more, the QoS in this path is relatively poor, therefore this path is changed to deactivation status, makes system can select other QoS to come transport service in the path preferably, thereby reduce the number of times that retransmits, saved bandwidth.For example, 4 paths are arranged between terminal A and the terminal B, wherein path 1 is a primary path, and path 2,3 and 4 is a backup path, and under the normal condition, this 4 paths is state of activation; After the QoS in path 1 variation, after using technical scheme in the embodiment of the invention and judging and be provided with, it is changed to deactivation status, flow can be switched on the backup path from primary path 1 according to SCTP mechanism, as path 2, thereby the system that makes can select QoS to come delivery flow rate than 1 other good path, path, compared with prior art, can avoid owing to continuing to use the path 1 of QoS variation to come delivery flow rate to cause increased frequency, waste bandwidth and the system resource of message re-transmission.
In embodiments of the present invention, can repeatedly obtain the change in count number of times of error counter, particularly, can service time sliding window mechanism obtains in real time, thereby can judge the QoS index in path more accurately.The length of sliding window was the official hour value, as 2 minutes.If the QoS in path is fine, do not retransmit, the number of times of the error counter EC change in count in the then sliding window just equals zero, and promptly the value of error counter EC does not change all the time; If the QoS in path is poor, when causing retransmitting because of packet loss, time delay index deterioration etc., the error counter EC change in count in the then sliding window can compare frequently.
The change in count number of times that obtains by sliding window is generally current time historical record before.For example, referring to Fig. 2, be sliding window schematic diagram of time.Wherein, frame of broken lines is represented sliding window, stipulated time is 3 minutes, current time is 10:20, then this cunning window obtain for being in 3 minutes before starting point, the current time with the current time, promptly from 10:17 begin within 3 minutes, the non-zero clearing change in count number of times of error counter, write down 8 values of error counter in it altogether, the variation of error counter has 7 times, is followed successively by: 1. EC=0 to EC=1; 2. EC=1 to EC=2; 3. EC=2 to EC=0; 4. EC=0 to EC=1; 5. EC=1 to EC=0; 6. EC=0 to EC=0; 7. EC=0 to EC=1.In changing for these 7 times, the non-zero clearing change frequency of mistake of statistics counter is 4 times, is respectively: 1. being the 1st variation, 2. is the 2nd variation, 4. is the 3rd variation, 7. is that the 4th changes, and then the error counter co-variationization is 4 times, and promptly message has retransmitted 4 times on this path.
