Fig. 5 detects the schematic flow sheet of another embodiment of method of path communication quality for the present invention, including：Step 51:Terminal A carries out initial setting up.Detection.
In the present embodiment, initial setting up includes：
(1) multiple first counters and multiple second counters are set, and the initial value of the first counter and the second counter is disposed as 0, wherein, each first counter is respectively used to count the transmission number of the heartbeat request message for detecting communication quality of different filling length, each second counter point
Not Yong Yu the reception number of corresponding heartbeat response message counted.
For example, the message length that can be detected in the present embodiment is as shown in table 1:
Table 1
When the message length that can be detected be shown in table 1 for 9 kinds when, 9 the first counters and respectively the second counter corresponding with each first counter can be then set respectively, be respectively used to statistical length for 8,16,32,64....1400 4 blunt Wen Lost bag rates.
(2) start and send cycle timer, the transmission cycle timer is used for the transmission cycle for indicating heartbeat request message, i.e., then send a heartbeat request message after cycle timer time-out is sent.
(3) detection cycle timer is started, the detection cycle timer is used to indicate detection cycle, i.e., examines and terminate after detection cycle timer expiry.
Step 52:After cycle timer time-out is sent, terminal A sends heartbeat request message to terminal B, and the value of the heartbeat request message purposes field of the heartbeat request message is set to indicate that heartbeat request message is used for the value that communication quality is detected, and heartbeat request message is filled the message content of certain length.
Referring to Fig. 6, on the basis of a upper embodiment, further comprising filling in the heartbeat request message of the present embodiment（Fill) field, the filling field can use TLV forms, by filling type（Fill Type), filling length（Fill Length) and filling content（Fill Content) composition.Fill Type value can be pre-defined value, and for example, 3, Fill Content value according to the content being pre-configured with by being filled, and Fill Length value is set according to the length difference of Fill Content content.For example, if configuration is filled in the way of table 1, Fill Content can fill each byte for 0x55,
Totally 8 byte content, now, Fill Length value is 8;Or, Fill Content can fill the content that each byte is OxAA, totally 16 byte, now, and Fill Length value is 16.It is 8 bytes that this, which fills length,（Byte content), it is 8 bytes that second, which can also fill length,（Byte content), or, it is 16 bytes that second, which can fill length,（Byte content).The specific content filled every time can be filled using random manner or by the way of pre-setting.
Further, need to ensure in each position to improve the content filled in the accuracy of transition detection, message（Bit) it can also be filled by 0 filling by 1.For example, for a byte, the content of-secondary filling is 0x55, i.e. 0101, then need to ensure that highest order has the situation for being filled 1 in the message subsequently sent, a secondary high position has the situation for being filled 0, secondary low level has the situation for being filled 1, and lowest order has the situation for being filled 0.Can be specifically that the content filled in next time is 0xAA.
Step 53:The value of the first counter corresponding with the length of the heartbeat request message of transmission is increased by 1 by terminal A after one above-mentioned heartbeat request message of every transmission.
For example, the length of the heartbeat request message filling content sent is 8, then by for filling the value increase by 1 that the heartbeat request message that length is 8 is transmitted the first counter of counting.
Step 54:Terminal B sends the heartbeat response message of corresponding filling length to port A after the heartbeat request message of a certain filling length is received.Location is obtained after exchanging, for example, the source address and destination address of the heartbeat request message received are respectively IP2 and IP4, then the source address and destination address of heartbeat response text can be filled with IP4 and IP2 respectively, and for remaining content of heartbeat request message, the especially filling content of heartbeat request message, can be with the correspondence position of complete copy to heartbeat response message.
Step 55:The value of corresponding second counter is increased by 1 by terminal A after the certain heartbeat response message of every one filling length of reception.
For example, the length of the heartbeat response message filling content received is 8, then by for filling the value increase by 1 that the heartbeat response message that length is 8 carries out the second counter of count pick up.
In addition, with the continuous time-out for sending cycle timer, heartbeat request message can be repeatedly transmitted, and corresponding heartbeat response message is received, i.e., above-mentioned step 52-55 can be repeatedly executed.
Step 56:After detection cycle timer expiry, terminal A calculates the message Lost bag rates of correspondence length.
Where it is assumed that being respectively A1 and B1 for the first counter and the count value of the second counter counted to the filling content that length is 8, then can obtain the message Lost bag rates that length is 8 is： ( A1-B1 ) /A1 ;Assuming that being respectively A2 and B2 for the first counter and the count value of the second counter counted to the filling content that length is 16, then can obtain the message Lost bag rates that length is 16 is：（A2-B2 ) /A2.Similar, the message Lost bag rates of remaining length can be obtained.
The present embodiment sets the counter of the different message lengths of correspondence by the way that heartbeat request message is detected for communication quality, it is possible to achieve the calculating to the message Lost bag rates of different length.
Fig. 7 detects the schematic flow sheet of another embodiment of method of path communication quality for the present invention, including：Step 71:Terminal A carries out initial setting up.
From unlike a upper embodiment, the present embodiment can be by detecting that the content of filling realizes detection to number of transitions.
In the present embodiment, initial setting up includes：
(1) saltus step counter is set, and the initial value of saltus step counter is set to 0.
(2) start and send cycle timer, the transmission cycle timer is used for the transmission cycle of the heartbeat request message indicated, i.e., then send a heartbeat request message after transmission cycle timer is overtime.
(3) detection cycle timer is started, the detection cycle timer is used to indicate detection cycle, i.e., detects and terminate after detection cycle timer expiry.
Step 72:After cycle timer time-out is sent, terminal A sends heartbeat request message to terminal B, and the value of the heartbeat request message purposes field of the heartbeat request message is set to indicate that heartbeat request message is used for the value that communication quality is detected, and heartbeat request message is filled the message content of certain length.
Specific filling mode may refer to an embodiment.
In addition, terminal A also needs to record the filling information of heartbeat request message.For example, the filling content that a source address and destination address are respectively IP2 and IP4 heartbeat request message is：Totally 8 byte, each byte fills 0x55.Further, in the case where that can fill the scene of different lengths, in addition it is also necessary to the length of record filling content, the length of such as record filling is： 8.
Step 73：Terminal B sends corresponding heartbeat response message after heartbeat request message is received to port A.
Step 74:Terminal A is after one heartbeat response message of every reception, compare the filling content in heartbeat response message and the filling content of corresponding heartbeat request message, if there is content saltus step, then per one bit of saltus step, then the count value of saltus step counter is increased by 1.
Wherein, if under the filling scene of single length, terminal A can determine after corresponding heartbeat request message and heartbeat response message that the filling content of relatively more corresponding heartbeat request message and the filling content of heartbeat response message obtain number of transitions according to source address and destination address.For example, filling length is fixed as under the scene of a certain length, if heartbeat request message R1 source address and destination address are respectively IP2 and IP4, the blunt literary A1 of heartbeat response ^ received source address and destination address is respectively IP4 IP2, then compare R1 filling content F1 and A1 filling content F2, if F1 is identical with F2, then show no saltus step, if F1 is different with F2 a certain position, it is 1 then to determine number of transitions, after analog, number of transitions is obtained.
In addition, if under the filling scene of different length, terminal A is determined after heartbeat request message and heartbeat response message according to source address and destination address, also to continue to determine corresponding heartbeat request message and heartbeat response message according to filling length Fill Length, and then the filling content and the filling content of heartbeat response message of relatively more corresponding heartbeat request message, obtain number of transitions.For example, filling length can be under the scene of different lengths, if heartbeat request message R1 source address and destination address are respectively IP2 and IP4, the blunt literary A1 of heartbeat response ^ received source address and destination address is respectively IP4 IP2, then can not as above a scene when directly compare R1 filling content F1 and A1 filling content F2, but also need to obtain R1 Fill Length parts and Al Fill Length parts, if Rl Fill Length parts are identical with Al Fill Length parts, just further compare R1 filling part F1 and A1 filling part, if F1 is identical with F2, then show no saltus step, if F1 is different with F2 a certain position, it is 1 then to determine number of transitions, after analog, obtain number of transitions.
In addition, with the continuous time-out for sending cycle timer, heartbeat request message can be repeatedly transmitted, and corresponding heartbeat response message is received, i.e., above-mentioned step 72-74 can be repeatedly executed.
Step 75:After detection cycle timer expiry, the value of saltus step counter is defined as content number of transitions by terminal A.
In addition, after needing to obtain the number of transitions of message of different length, one saltus step counter can be set to the message of each filling length, number of transitions is determined using the saltus step counter of correspondence different length respectively with the determination of the Lost bag rates of the similar message to different length.
Mode Que shown in 4 or Fig. 5 Dings Lost bag numbers, and determines in the way of shown in Fig. 6 number of transitions.
The present embodiment sets saltus step counter by the way that heartbeat request message is detected for communication quality, it is possible to achieve the calculating to number of transitions.
In addition, the embodiment of the present invention, which increases heartbeat request message, can realize that path communication quality as above is detected after heartbeat request message purposes field.Simultaneously, the heartbeat request message of the embodiment of the present invention can also be served only for existing break-make detection, now, the value of the heartbeat request message purposes field of heartbeat request message can be set to show the value that heartbeat request message is common heartbeat request message, afterwards, it can be handled according to existing break-make detection mode.
After the data of above-mentioned communication quality detection are obtained, different applications can be carried out.Li such as , Lost bags rates are more than after certain threshold value, such as 0.1%, and the sub-health state of backup path is presented by the similar prompting mode such as alarm, diary, reminds user to be investigated, it is ensured that the communications status that backup path is kept fit.When the bag Zong Shi Bei Lost of length-specific are abandoned, presented by the similar prompting mode such as alarm, diary, the progress for reminding user purposive is investigated, it is ensured that the communications status that backup path is kept fit.Backup path communication quality result of detection provides decision data to belonging to SCTP more according to QoS toggle paths, it is ensured that belong to the accurate and effective switched according to QoS SCTP more.
