Embodiment
The embodiment of the invention is selected suitable sublink and is used for the propagation delay time sensitive traffic according to the propagation delay time of each included sub-links of bundle link, to improve the delay sensitive traffic transmission quality on the bundle link.The present invention is further described through specific embodiment below in conjunction with accompanying drawing.
The inventor is through the discovery of concentrating on studies, and the reason that delay sensitive traffic transmission quality can not get guaranteeing on the bundle link in the prior art normally propagation delay time of certain bar (a bit) sublink of bundle link is excessive.For example; Still with Fig. 1 example; When certain sub-links in the wide area network because equipment or network change when causing chain-circuit time delay to increase greatly; Router-A and router B as access device can't perceive, and therefore, router-A still can carry out the fragment message transmission according to original bundle link on all sublinks.The propagation delay time of sublink of supposing transmission burst 4 is very big; Router B must be with the burst that arrives first 1,2,3 long-time buffer memorys so; Just can recombinate etc. after fragmented 4 arrival; Even this makes the sublink of transmitting other burst than fast 4 times of the sublink of transmitting burst 4, the transmission of whole message still has to limited by the maximum sublink of time delay.And; This transmission mechanism can cause the professional big message of sending out earlier to be postponed (certain burst of this message is through the big link of time delay); The smaller slightly message of then sending out can be routed device B reorganization prior to above-mentioned big message and transmit, thereby causes the message transmissions order of whole service to be upset.Delay sensitive is professional, like the business of speech business or use transmission control protocol (TCP, Transfer Control Protocol) application, because message time delay and order are had relatively high expectations, is flagrant for above-mentioned situation therefore.As seen from the above analysis, prior art adopts the bundle link technology, though increased the network bandwidth, the delay sensitive traffic transmission that can not be guaranteed quality.
According to above analysis, the embodiment of the invention is according to the propagation delay time of sublink, selects wherein the less sublink of time delay and comes the propagation delay time sensitive traffic, to reach the purpose that improves delay sensitive traffic transmission quality.Shown in Figure 2 is the said flow chart that on bundle link, sends the method for data of the embodiment of the invention, and said bundle link comprises a plurality of sublinks.As shown in Figure 2, said method comprising the steps of:
Here, can adopt various existing simultaneous techniquess to realize that the system clock between the terminal device is synchronous, consistent with the system clock that guarantees terminal device.Wherein a kind of method of synchronization can be: time protocol (NTP Network Based; Network Time Protocol) system clock of synchronous bundle link terminal device; Be bundle link local terminal equipment and opposite equip. respectively with network on the clock source synchronised of appointment, and then realize that the system clock between the terminal device is synchronous.
Here, said chain circuit transmission time delay is meant the propagation delay time of message at link layer.For bundle link, the message formerly link layer of local terminal equipment carries out burst and on each sub-links, sends then, recombinate at the link layer of opposite equip., so the propagation delay time of link layer more can accurately reflect the actual transmissions quality of network.And between local terminal and opposite end through Internet protocol (IP; Internet Protocol) propagation delay time that obtains of mode can only embody the transmission quality overview of whole big net (whole bundle link) between local terminal and the opposite end; Can't carefully distinguish the chain circuit transmission time delay of each sublink, for example, time-delay when the IP layer adopts the Ping mode to obtain; The Ping message is specifically also unclear via which sublink of bundle link, therefore can not accurately reflect the transmission quality of sublink.
Concrete, the chain circuit transmission time delay in the present embodiment on the sublink can obtain according to following steps:
Step 221; Local terminal equipment sends test packet to opposite equip. respectively on each sub-links of bundle link; Carry the transmitting time stamp of said test packet and the sublink information of sending said test packet in the said test packet, the system clock of said opposite equip. and said local terminal equipment is synchronous;
Step 222; The time of reception that opposite equip. is noted when receiving said test packet stabs; Send the test response message then said test packet is responded, carry said transmitting time stamp, said sublink information and said time of reception in the said test response message and stab;
Step 223, local terminal equipment receive said test response message, obtain time of reception stamp, the transmitting time of wherein carrying and stab and sublink information, calculate poor that said time of reception stabs and transmitting time is stabbed, thereby obtain the chain circuit transmission time delay of corresponding sublink.Here the chain circuit transmission time delay that calculates is the unidirectional transmission time delay of the local terminal equipment of bundle link to opposite equip..
Because chain circuit transmission time delay possibly change with the variation of factors such as network topology, flow; Therefore in order to reflect the current chain circuit transmission time delay of each sub-links more accurately; Local terminal equipment can also periodically send said test packet in the present embodiment, to obtain the propagation delay time of the current reality of each sub-links.
Test packet described in the present embodiment and test response message are link layer message.Be example with multilink point-to-point (MP, Multilink Point to Point Protocol) and multilink frame relay (MFR, Multilink Frame Relay) network respectively below, the link layer message structure that can adopt in the above-mentioned steps is described.MP uses a plurality of ppp link bindings, and MFR uses a plurality of FR multilink bundlings.
For the MP network, the form of said test packet is as shown in table 1 below:
| The PPP heading | The MP heading | Test serial number | Message flag | Transmitting time is stabbed | Send sublink information |
| Link header | The MP link header | The test serial number of current transmission | Test packet | Fill in current system time | Send the sublink numbering of this message |
Table 1
For the FR network, the form of said test packet is as shown in table 2 below:
| The FR heading | The MFR heading | Test serial number | Message flag | Transmitting time is stabbed | Send sublink information |
| Link header | The MFR link header | The test serial number of current transmission | Test packet | Fill in current system time | Send the sublink numbering of this message |
Table 2
For example, in the MP network, include four PPP sublinks, be numbered 1,2,3,4 respectively for every PPP sublink when bundle link is current; Every at a distance from 15 seconds, local terminal equipment sends test packet to four PPP sublinks respectively, and wherein the test packet of the 1st PPP sublink transmission is as shown in table 3 below:
| The PPP heading | The MP heading | Test serial number | Message flag | Transmitting time is stabbed | Send sublink information |
| Link header | The MP link header | 1 | Test packet | Current system time | 1 |
Table 3
Article 2, the test packet of PPP sublink transmission is as shown in table 4 below:
| The PPP heading | The MP heading | Test serial number | Message flag | Transmitting time is stabbed | Send sublink information |
| Link header | The MP link header | 1 | Test packet | Current system time | 2 |
Table 4
The test packet of other PPP sublinks is similar, repeats no more.
The opposite equip. of bundle link should return the test response message to the bundle link that receives this test packet after receiving the above-mentioned test packet that local terminal equipment sends, the test response message can be not send receiving on the sublink of this test packet.The test response message is constructed on the basis of test packet, and for the MP network, the form of test response message is as shown in table 5 below:
| The PPP heading | The MP heading | Test serial number | Message flag | The transmitting time of carrying in the test response message is stabbed | Time of reception stabs | The sublink information of carrying in the test response message |
| Link header | The MP link header | The test serial number of the test packet of current response | The test response message | The transmitting time of test packet is stabbed | The time of reception of test packet stabs | The sublink numbering of carrying in the test packet |
Table 5
For the MFR network, the form of test response message is as shown in table 6 below:
| The FR heading | The MFR heading | Test serial number | Message flag | The transmitting time of carrying in the test response message is stabbed | Time of reception stabs | The sublink information of carrying in the test response message |
| Link header | The MFR link header | The test serial number of the test packet of current response | The test response message | The transmitting time of test packet is stabbed | The time of reception of test packet stabs | The sublink numbering of carrying in the test packet |
Table 6
For example, as shown in table 7 below to the test response message of the test packet shown in the table 3:
| The PPP heading | The MP heading | Test serial number | Message flag | The transmitting time that the test response message carries is stabbed | Time of reception stabs | The sublink information that the test response message carries |
| Link header | The MP link header | 1 | The test response message | The transmitting time of test packet is stabbed | The time of reception of test packet stabs | 1 |
Table 7
Local terminal equipment promptly can calculate poor that the time of reception that wherein carries stabs and transmitting time is stabbed after receiving the test response message shown in the table 7, obtain the chain circuit transmission time delay of the 1st PPP sublink.
Certainly, present embodiment can also adopt other various existing time-delay measuring methods to measure the chain circuit transmission time delay of each sub-links.For example; Under opposite equip. and the nonsynchronous situation of local terminal device systems clock, (need not the step 21 of synchronous terminal device system clock this moment); Carry transmitting time when sending test packet on the local terminal equipment sub-links and stab T1; Opposite equip. recorder is stabbed T2 to the time of reception of test packet, on same sub-links, returns the test response message to local terminal equipment then, and the transmitting time of this test response message is stabbed and is T3; The time of reception that receives this test response message under the local terminal equipment records stabs T4, thereby the round-trip delay of message on this sublink is: T=T4+T2-T1-T3, and then can be with the chain circuit transmission time delay of T/2 as this sublink.
In the above-mentioned steps 23,, select the less sublink propagation delay time sensitive traffic of time delay through chain circuit transmission time delay and preset time delay threshold with each sub-links of bundle link.Here; The size of said time delay threshold value can be provided with and adjust according to the professional current transmission quality of delay sensitive on the bundle link; For example when transmission quality is relatively poor, can reduce said time delay threshold value, when transmission quality is better, can suitably increase said time delay threshold value.Below provide several kinds of modes that said time delay threshold value is set:
1) allows propagation delay time according to the professional maximum of said delay sensitive, said time delay threshold value is set.
Delay sensitive is professional; Comprise speech business, facsimile service, video traffic and TCP applied business etc., usually professional propagation delay time is had corresponding requirement, for example; The maximum of facsimile service allows propagation delay time to be generally 90ms; Therefore, in order to guarantee delay sensitive traffic transmission quality, need from bundle link, select propagation delay time to be not more than the said maximum sublink of propagation delay time that allows and send said delay sensitive business.Certainly for the transmission quality that makes sensitive traffic better assurance is arranged; Can be rule of thumb or the professional actual transmissions quality of delay sensitive; Said time delay threshold value is set to be slightly smaller than a said maximum value that allows propagation delay time; For example, the maximum permission propagation delay time to above-mentioned 90ms can the time delay threshold value be set to 85ms.
2) according to minimum transfer time delay and preset time delay depart from threshold value δ's and value; Said time delay threshold value is set; Wherein, It is the maximum permissible value that chain circuit transmission time delay departs from said minimum transfer time delay that reckling in the chain circuit transmission time delay that said minimum transfer time delay is said all sublinks of bundle link, said time delay depart from threshold value δ, specifically can preestablish according to the transmittability of said bundle link and the buffer memory ability of said opposite equip..
Here, time delay departs from the numerical value that chain circuit transmission time delay that threshold value δ is meant acceptable sublink departs from said minimum transfer time delay.If the chain circuit transmission time delay of certain sub-links departs from the numerical value of said minimum transfer time delay and exceeds δ, then this sublink not can be used as first kind sublink.The buffer memory ability of transmittability and opposite equip. that time delay departs from threshold value δ and bundle link is relevant.Below illustrate and how to select the δ value.
Suppose to use 8 FR sublink binding transfer files host-host protocol (FTP, File TransferProtocol) business, every FR sublink bandwidth 2M byte, the total bandwidth of the bundle link of 8 FR sublink formation then is the 16M byte.The fragment cache memory ability of supposing the bundle link opposite equip. is 1024 fragment messages, and each burst maximum length is 500 bytes.Calculate with extreme case; Suppose that local terminal equipment has sent the different bursts of same message simultaneously on a plurality of sublinks; So, under the prerequisite that the opposite equip. buffer memory all takes, for guaranteeing not occur the situation that burst is lost; Maximum delay between burst that this message on the opposite equip. receives the earliest and the burst that receives the latest equals the merchant of the total size of buffer memory with the bandwidth of bundle link of opposite equip., that is: (500*1024)/16M=31ms.
The meaning of above-mentioned 31ms is: according to the transmittability of bundle link and the buffer memory ability of opposite equip.; The 31ms data quantity transmitted can be filled up the buffer memory of opposite equip. on the bundle link, therefore, and on opposite equip.; If the time delay between the burst of burst that same message receives the earliest and reception the latest is greater than 31ms; Then can cause when receiving the burst that receives the latest, the burst that receives the earliest of this message is lost because of buffer memory overflows, thereby causes message to take defeat.Therefore, can time delay depart from threshold value δ here and be set to 31ms.If consider time delay such as network equipment transmitting-receiving message, reorganization burst; Perhaps professional some characteristics own; Can also be multiplied by a certain coefficient to the 31ms that calculates, suitably to adjust up or down, the numerical value that will obtain after will adjusting then departs from threshold value δ as time delay.
Here, said time delay threshold value be set to said minimum transfer time delay and time delay depart from threshold value δ's and value, select the first kind sublink that chain circuit transmission time delay is no more than said time delay threshold value then and be used for the propagation delay time sensitive traffic.Chain circuit transmission time delay in the first kind sublink of selecting like this between each sub-links differs and is no more than said time delay and departs from threshold value δ; Thereby can guarantee under above-mentioned supposed situation, can not take place message takes defeat; Therefore, can improve the traffic transmission quality to a certain extent.
For example, suppose in above-mentioned 8 FR sublinks, time delay is set departs from threshold value δ=31ms, and the chain circuit transmission time delay of each sub-links to be respectively: 10ms, 25ms, 15ms, 20ms, 30ms, 30ms, 100ms and 50ms.Obviously, the minimum transfer time delay is 10ms, and the time delay threshold value is 31+10=41ms.So,
The 1st sub-links: 10ms＜41ms, this sublink can be used;
The 2nd sub-links: 25ms＜41ms, this sublink can be used;
The 3rd sub-links: 15ms＜41ms, this sublink can be used;
The 4th sub-links: 20ms＜41ms, this sublink can be used;
The 5th sub-links: 30ms＜41ms, this sublink can be used;
The 6th sub-links: 30ms＜41ms, this sublink can be used;
The 7th sub-links: 100ms＞41ms, this sublink is unavailable;
The 8th sub-links: 50ms＞41ms, this sublink is unavailable;
Thereby selecting the 1st～6 sub-links is first kind sublink, is used for the propagation delay time sensitive traffic.When network change or the network equipment are unusual, can also be updated periodically the chain circuit transmission time delay of each sub-links according to above-mentioned steps 22, reselect first kind sublink then.
3) in addition, can also allow the smaller in the propagation delay time according to the professional maximum of above-mentioned and value and said delay sensitive in the present embodiment, said time delay threshold value is set, above-mentioned and value is meant that said minimum transfer time delay and said time delay depart from threshold value and value.Obviously, the first kind sublink of selecting like this is strict more, can guarantee delay sensitive traffic transmission quality better.
In the above-mentioned steps 24, can the business that said bundle link need send be divided into the professional and insensitive business of time delay of delay sensitive; Then; It is professional to utilize said first kind sublink to send said delay sensitive; Utilize in all sublinks or all sublinks of said bundle link other sublink except that first kind sublink to send the insensitive business of said time delay, thereby can improve delay sensitive traffic transmission quality.
Can find out from the above; Present embodiment is in the propagation delay time of each sub-links of link step analysis bundle link of link network; Obtain link quality data more accurately; And according to the propagation delay time of sublink select transmission quality preferably sublink come the propagation delay time sensitive traffic, thereby improved delay sensitive traffic transmission quality.
