Description
Technical field
The present invention relates to the communications field, relate in particular to frame relay stripping strategy problem.
Background technology
Along with networks development, real time business is also further expanded, the most tangible for example VoIP (Voice overIP), the widespread usage of VoFR speech businesses such as (Voice over Frame Relay).The application of VoIP on router makes speech business to be undertaken by IP network, comprises traditional telephone service and fax.VoIP realizes by packets of voice, and in VoIP, digital signal processor DSP (Digital SifnalProcessor) is with voice signal packing framing and be stored in the grouping bag and transmit.VoIP mainly is a kind of software solution, supports but need install the speech interface plate additional on router.Similar with VoIP, what the VoFR technology provided in Frame relay network transferring voice and voice class data (as the analogue data of facsimile data, modulator-demodulator) may.VoFR directly is encapsulated in voice signal in the frame relay frame, transmits at two layers.To this real time business of voice, voice quality is most important.In order to improve voice quality, the problem that needs the most critical of solution is exactly to reduce the time delay of voice packet, prevents the shake of voice packet.This problem is especially obvious when voice and data simultaneous interpretation.
VoFR has expanded the application of frame relay, makes the terminal use to carry out different business such as data, voice and fax simultaneously on a lease line, improves bandwidth availability ratio greatly.Because VoFR is while transferring voice and data on same circuit, voice message is generally less, and the data message length variations is big, occurs easily causing voice delay time to increase in order to send big data message, shakes tangible phenomenon.In order to address this problem, can adopt the method for data being carried out burst.By being split as big data message a plurality of and the sizable small messages of voice, voice and fragment data send at interval, and voice are in time handled, and have avoided the generation of delay variation.
As shown in Figure 1, be the schematic diagram that data fragmentation sends.
Such as, the router of Cisco has adopted a kind of method of fixedly burst.In case disposed burst, all data that surpass the burst size are all split, under the situation of voice and data simultaneous interpretation,, send if there is data message also can be split as burst even voice are hung up.General packets of voice message is all less, greatly about the 20-60 byte, causes voice to be delayed for fear of big message, and the burst size of configuration is general suitable with voice message, and for example when voice were 30 bytes, can dispose the burst size was 80 bytes.All packets that surpassed 80 bytes can be that unit is split with 80 bytes all like this.
In case Cisco's this configuration burst size is with regard to nonadjustable mode underaction.Because message fragment need add the fragment message head, for example, the IP message of 1500 bytes is done the FRF.12 burst by 30 byte-sized, and the total bandwidth ratio that message takies behind the burst not fragment message increases about 26%.Simultaneously message is carried out burst and recombinates also will consuming the extra CPU time.And the initial purpose that burst is introduced is exactly when guaranteeing voice and data simultaneous interpretation, guarantees the quality of voice, avoids big packet transmission to cause the time-delay and the shake of voice.If voice call finishes, it is just nonsensical that carry out burst to the data message this moment, and data message is burst or send with bigger burst size not fully.
Summary of the invention
Purpose of the present invention is exactly the situation of change according to real-time voice, and the strategy of dynamic adjusting data burst improves bandwidth availability ratio, avoids extra consumption.

Embodiment
Below in conjunction with Figure of description the specific embodiment of the present invention is described:
The core concept that frame relay stripping strategy of the present invention is dynamically adjusted with voice is when not having the voice real time business on the line, for conserve bandwidth, improves the efficient that data message sends, and data message is burst or strengthen the threshold value of burst not.When the voice real time business is arranged on the line, in order to guarantee the transmission quality of speech data, the data message that transmits is carried out burst send, to guarantee the normal transmission of speech data.
This shows that in fact the present invention comprises two technical schemes.
One of the present invention program: the upper layer data message is carried out burst send, set two burst threshold value N1, N2 in the scheme, N1＜N2, wherein threshold value N1 is general packets of voice message size, threshold value N2 is the packet message size.
On stripping strategy, system configuration two burst threshold value N1, N2, wherein, threshold value N1, when being the speech data simultaneous interpretation, the burst threshold value when voice call is being carried out adopts the burst size of N1 configuration that the data message is carried out burst, this moment voice message is carried out the big or small identical of burst with system, guarantee that voice can not delayed time, threshold value N2 is the burst threshold values of voice when not existing, after voice are hung up, data fragmentation burst size switches to the N2 value, and the bandwidth consumption that can avoid burst to bring is raised the efficiency like this.
As shown in Figure 2, this method further may further comprise the steps:
A, judge whether the upper strata message is voice message, if, change step f over to, if not, change step b over to;
For the data message that the upper strata that receives sends, the type of this data message is at first judged by system, because system will guarantee the priority of voice message, guarantees to take priority, to guarantee quality of voice transmission when transmitting voice message.If the data message of receiving is a voice message, then burst does not directly send, if the non-voice message is taked stripping strategy that it is carried out burst again and sent, with conserve system resources.
B, judge whether to dispose burst, if, change step c over to, if not, change step f over to;
This is to judge whether the data message that receives needs to carry out the step of burst, the size of data message is different, the data message that has is less, may be also big less than voice message, if also take the strategy of burst for such data message, the expense of the first-class byte of increase message that will be extra, disagree with the original intention of saving line resource on the contrary, therefore, here add one is judged whether the non-voice message needs the step of burst, and this judges whether to dispose burst and promptly judges by size of data.If surpass the threshold value N1 that burst is set, then it carried out burst.
C, judge whether to exist audio call, if, change steps d over to, if not, change step e over to;
This is a key point place of the present invention, the present invention adjusts stripping strategy on the basis of judging transmission data type on the circuit, to guarantee normally carrying out of speech business, if there is audio call on the circuit, be that the data that transmitting on the circuit are speech data, unaffected for the speech business that guarantees to have existed so, will carry out corresponding burst to the upper layer data message, the data fragmentation of being got is mixed in sends in the voice message, unaffected to guarantee ongoing speech business.
D, carry out burst according to N1 and send;
If there is audio call on the circuit, be to have speech data to transmit on the circuit, so just, upper layer data being carried out burst sends, the size of this burst is the size of threshold value N1, promptly upload the sizableness of sending voice message with circuit, because big message data causes voice to be delayed, produce the phenomenon of shake to guarantee not.
E, carry out burst according to N2 and send;
If there is not audio call on the circuit, be not have speech data to transmit on the circuit, also upper layer data being carried out burst sends, the size of this burst is the size of threshold value N2, promptly with on the circuit transmit the sizableness of data message, the wasting of resources that causes to reduce the increase fragment message head that the too small data message burst that brings of burst threshold value brings.
F, directly transmission.
When the upper strata message is a voice message, perhaps the upper strata message is a data message, but its size does not just need to carry out burst to this message when being no more than burst threshold value N1 or N2, directly sends to get final product.
The present invention program's two: the upper layer data message is carried out burst send, set a burst threshold value N1, threshold value N1 is general packets of voice message size.
This is actually another processing of previous scheme, on stripping strategy, system configuration a burst threshold value N1, threshold value N1, when being the speech data simultaneous interpretation, burst threshold value when voice call is being carried out, adopt the burst size of N1 configuration that the data message is carried out burst, this moment voice message is carried out the big or small identical of burst with system, guarantee that voice can not delayed time, after voice are hung up, upper layer data is not carried out burst, directly send, the bandwidth consumption that can avoid burst to bring is raised the efficiency like this.
By judging the type that transmits data message on the circuit, come dynamic adjusting data burst threshold value.
As shown in Figure 3, this method further may further comprise the steps:
A, judge whether the upper strata message is voice message, if, change step e over to, if not, change step b over to;
For the data message that the upper strata that receives sends, the type of this data message is at first judged by system, because system will guarantee the priority of voice message, guarantees to take priority, to guarantee quality of voice transmission when transmitting voice message.If the data message of receiving is a voice message, then burst does not directly send, if the non-voice message is taked stripping strategy that it is carried out burst again and sent, with conserve system resources.
B, judge whether to dispose burst, if, change step c over to, if not, change step e over to;
This is to judge whether the data message that receives needs to carry out the step of burst, the size of data message is different, the data message that has is less, may be also big less than voice message, if also take the strategy of burst for such data message, the expense of the first-class byte of increase message that will be extra, disagree with the original intention of saving line resource on the contrary, therefore, here add one is judged whether the non-voice message needs the step of burst, and this judges whether to dispose burst and promptly judges by size of data.If surpass the threshold value N1 that burst is set, then it carried out burst.
C, judge whether to exist audio call, if, change steps d over to, if not, change step e over to;
This is a key point place of the present invention, the present invention adjusts stripping strategy on the basis of judging transmission data type on the circuit, to guarantee normally carrying out of speech business, if there is audio call on the circuit, be that the data that transmitting on the circuit are speech data, unaffected for the speech business that guarantees to have existed so, will carry out corresponding burst to the upper layer data message, the data fragmentation of being got is mixed in sends in the voice message, unaffected to guarantee ongoing speech business.
D, carry out burst according to N1 and send;
If there is audio call on the circuit, be to have speech data to transmit on the circuit, so just, upper layer data being carried out burst sends, the size of this burst is the size of threshold value N1, promptly upload the sizableness of sending voice message with circuit, because big message data causes voice to be delayed, produce the phenomenon of shake to guarantee not.
E, directly transmission.
When the upper strata message is a voice message, perhaps there is not audio call on the circuit, promptly there is not speech data to transmit on the circuit, this message is not just needed to carry out burst, directly transmission gets final product.
See a specific embodiment below, as shown in Figure 4, in this embodiment, comprise a frame-relay network, now desire on frame-relay network, to transmit simultaneously voice message and data message, this data message is carried out burst transmit in the process of transmission.
We are defined as voice-level (the burst grade when voice exist) with threshold value N1; Threshold value N2 is defined as data-level (the burst grade when voice do not exist).In this transmission course, speech bandwidth is 20k, and the data fragmentation size during no voice is 500 bytes, and promptly data-level is 500 bytes, and the data fragmentation size was 80 bytes when voice were arranged, and promptly voice-level is 80 bytes.In system, do following configuration:
The attribute vofr huawei-switch of interface Serial0 encapsulation frame-relay ip address 100.1.1.2 255.255.0.0 frame-relay map ip 100.1.1.1100 frame-relay interface-dlci100 class vofr // quote vofr map-class configuration // enable huawei vofr function map-class frame-relay vofr frame-relay voice bandwidth 200000 // distribution speech bandwidth is that the data fragmentation size of 20k frame-relay fragment 500 data-level // configurations during without voice is that 500 byte frame-relay fragment, 80 voice-level // the data fragmentation size is 80 bytes when disposing voice
Under above-mentioned configuration, get through No. one phone, simultaneously with 1000 byte-sized Ping 100.1.1.1 addresses, can be with the big or small burst of packet according to 80 bytes; Hang up voice this moment, and burst big young pathbreaker change, and packet carries out burst according to the size of 500 bytes.
Under above-mentioned configuration, get through No. one phone, system will judge whether the upper strata message is voice message, if there is not data message in voice message, be guarantee the quality of voice transfer, to upper strata message burst not, directly with its transmission; If not voice message, when the size of data message during less than the threshold value Voice-level of default, not to its burst, directly with its transmission; When the size of data message during, will be determined further it greater than the threshold value Voice-level of default.
Then, judge whether this message is the speech data simultaneous interpretation.If judged result will be carried out burst to this data message and send for being, the burst size equals Voice-level; If judged result then will be carried out burst to it and send for not, the burst size is threshold value N2, as Data-level.
It is only relevant with local router that burst of the present invention is dynamically adjusted strategy, the reorganization of message do not influenced, so do not relate to compatibility issue between the different vendor.
The invention provides the method for data fragmentation strategy with the voice dynamic change, can whether have dynamic adjustment burst size according to real time business such as voice, whether control carries out data fragmentation.Conserve bandwidth and reduction are handled and are consumed.
The above; only for the preferable embodiment of the present invention, but protection scope of the present invention is not limited thereto, and anyly is familiar with those skilled in the art in the technical scope that the present invention discloses; the variation that can expect easily or replacement all should be encompassed within protection scope of the present invention.Therefore, protection model scope of the present invention should be as the criterion with the protection range of claims.
