Description
Technical field
The present invention relates to mobile communication technology, particularly relate to the processing method of communication field business datum.
Background technology
According to service quality (QoS) requirement to network, Packet Service generally can comprise Four types: conversation class (Conversational Class), stream class (Streaming Class), interactive class (InteractiveClass) and background classes (Background Class).Wherein conversation class and stream class service need network to provide normally carrying out of more stable bandwidth guarantee business usually, are therefore also called and ensure band width service (Guaranteed BitRate Services, GBR Services).Corresponding, the Bandwidth guaranteed that interactive class and background business do not need network to provide stable, can the fluctuation of bandwidth in tolerance service process, is therefore called as non-assured bandwidth business (Non-GBR services).
Although be all Non-GBR business, interactive class and background business different again to the qos requirement of network.
In interaction service, client (such as a, mobile phone, PC) a network distally equipment (such as WEB server can be passed through, ftp server etc.) request msg, remote equipment process request, and the data of request are returned to client.Typical interaction service, can be such as use the WEB of http protocol to browse, user is at address (the Uniform Resource Locator of browser input webpage, URL), browser obtains the IP address (alternatively) of server by dns resolution, sets up TCP be connected with server, then page request is sent by http protocol to server, after server processing requests, result is returned to browser, browser is shown to user after result being formatd.Due to current webpage Rich Media (rich media), in addition to text, also may comprise a lot of picture embedded, animation, the multimedia objects such as sound, therefore many times complete display webpage is wanted, browser needs first to resolve page framework file (normally one section of html text), if there is the object of embedding in framework, browser is connected by one or more of TCP again asks to server the object downloading multiple embedding respectively, comprise other html text, picture, animation, sound etc., the size of each object may from several kilobytes to a few Mbytes not etc.User can to meet with a response result after being desirably in the request of sending (as webpage clicking link) faster.
Similar with interaction service, background business is also a client distally equipment (such as a server) request msg, and remote equipment process request, returns the data of request to client.With interaction service unlike, in general, the size of data of background business request is general larger, such as download a file, its file size can reach a few M, and hundreds of M even goes up G, therefore returns the transmitting continuous chronic of the data of request from server, may several minutes, a few hours, even a couple of days.
Due in a lot of network environment, to non-assured bandwidth business, network can be only terminal and provide a transparent data pipe, namely the data transmitting what business in this pipeline are controlled by terminal (user) oneself, the type of service of network not perception data stream, can not distinguish the flow of different business.Therefore reality is, interactive class and the background business with different QoS requirement often all operate in (the background classes carrying that normally providing does one's best serves) in identical data pipe, are subject to identical processing policy in a network.
Consider from the qos requirement of business, need to interaction service priority treatment, (Deep Packet Inspect such as can be resolved based on deep packet, etc. DPI) technology processes, network element can distinguish the data flow using the agreements such as HTTP, after differentiation, give the interactive service priority treatment using the agreements such as HTTP.But, because the expense of DPI function itself is very large, and http protocol itself also can be used to provide the services such as file download, and file download user can design very easily in conjunction with P2P technology and adopt the honeypot that downloads of http protocol, thus also enjoy same priority treatment, be affected when causing user to enjoy interactive service.
Summary of the invention
Embodiments provide a kind of processing method and equipment of business datum.Make a business datum stream transmission procedure can obtain priority treatment in the incipient stage.
A processing method for business datum, comprising: the packet of receiving data stream passage; When judging that current transmission is the transfer of data newly started, start introductory period processing procedure; Within the introductory period, the packet that this data flow path is transmitted is processed according to preference strategy.

Embodiment
The transfer of data feature of interaction service is that transfer of data is sudden, and lasting transience, such as every several seconds to a few minutes, there is transfer of data, after each transmitting continuous several seconds to tens seconds, transfer of data stops, and then transfer of data next time occurs, so repeatedly.And the transfer of data feature of background business is that data duration is long, after transfer of data starts, last for several minutes is even longer to dozens of minutes always in meeting.
Below for Transmission Control Protocol, the transmission feature of interactive service and background business in Transmission Control Protocol in same transmission pipeline is described.
1, in Transmission Control Protocol, employ one be called that the speed of " slow turn-on " sounds out mechanism.See Fig. 1, such as, t0 ~ t1 is slow start stage.At slow start stage, every a RTT cycle, the speed of TCP transmit leg doubles; Until the congestion window size that transmit leg is safeguarded reaches Slow start threshold value ssthresh, or transmit leg detects packet loss phenomenon, namely stops slow start stage and enters congestion avoidance phase (such as, after t1).Wherein, the transfer of data feature due to interaction service is that transfer of data is sudden, and lasting transience, therefore in the shorter duration of interactive service, the very large a part of time is in slow start stage.Namely operate in (relative to other background business) in lower transmission rate, cause and obtain data and to be shown to time of user elongated from server.And the transfer of data feature of background business is that data duration is long, after transfer of data starts, last for several minutes is even longer to dozens of minutes always in meeting, therefore slow start stage only accounts for very short a period of time in the transfer of data duration of background business, after end slow start stage enters congestion avoidance phase, within follow-up most of business hours, all operate in higher transmission rate.
If 2 occur packet loss phenomenon in TCP transmission process, then current transmission rate can sharply decline, and see Fig. 1, as there is packet loss when t2, visible, transmission rate sharply declines.To interaction service, no matter packet loss occurs in slow start stage or congestion avoidance phase, and all can make service operation in lower transmission rate, the service response time is longer, and Consumer's Experience is poorer.And to background business, can speed recover gradually to promote after speed decline after generation packet loss, therefore occur that packet loss affects not quite concerning long-term business transmission once in a while.
In addition, to connect the maximum bandwidth that can obtain relevant with RTT for TCP.When the TCP receive window size of main frame is constant, RTT is shorter, and it is larger that TCP connects the bandwidth that can obtain, and transmission rate is higher.
For the feature that interactive service and background business transmit, for making full use of Internet resources, interactive service and background business are all had start faster to transmit separately, improve the Experience Degree of user, one embodiment of the present of invention provide a kind of business data processing method: the packet of receiving data stream passage; When judging that current transmission is the transfer of data newly started, start introductory period processing procedure; Within the introductory period, the packet that this data flow path is transmitted is processed according to preference strategy.Wherein, be called " introductory period " in the priority treatment of every data transfer incipient stage.By the method, can give and the process of higher priority an incipient data flow.
Such as, if business (such as, interactive service and background business) what adopt is Transmission Control Protocol, then this TCP connects and can complete slow start stage faster, reaches higher speed fast, and higher priority can shorten transmission RTT simultaneously, make due to TCP receive window size and the transmission rate-limit raising that two-way time, restriction produced, thus reach speed faster, reduce or avoid the appearance of packet loss, and then the situation appearance reducing or avoid transmission rate sharply to decline.This section is called " introductory period " in the priority treatment of every data transfer incipient stage.
As shown in Figure 2, be the process flow schematic diagram of a kind of business datum that another embodiment of the present invention provides, make the user of interaction service better can enjoy interactive service, can comprise the following steps.
The packet of step 101, receiving data stream passage;
Wherein, data flow path can refer to the logical channel safeguarded in network element or terminal for the data flow of controls transfer user and the data structure of being correlated with.
Step 102, when judging that current transmission is the transfer of data newly started, start introductory period processing procedure;
Wherein, the data stream transmitting newly started can refer to the transfer of data again started after idle special time length in this data flow path, or also can refer to the initial data transmission in a newly-built data flow path.When in data flow path only transmission interactive service time, the behavior of user, such as, click the link of a new webpage at regular intervals, will trigger one section of data stream transmitting newly started.And if in data flow path transmission background business, due to the continuation of background business transmission, in passage, most time has data packet transmission always, does not that is substantially have the situation of passage free time, the data stream transmitting of " newly starting " also just seldom can be detected.
In another embodiment of the invention, judge whether current transmission is that the transfer of data newly started in data flow path can comprise with under type one:
Such as, mode A: whether the interval duration judging the upper packet that current data packet is adjacent, exceed thresholding, if exceeded, current transmission is the transfer of data newly started.Wherein, when passage just sets up (or recover), during owing to there is no a upper packet, so also think that the time interval exceedes thresholding.
Such as, mode B: in the thresholding duration before judging to receive current data packet, whether the delivery flow rate of described data flow path is 0, if be 0, then current transmission is the transfer of data newly started.Namely according in a period of time before receiving current data packet, if user does not transmit data, then think that current transmission is the transfer of data once newly started.
Such as, mode C: in the thresholding duration before judging to receive current data packet, whether the transmission rate of described data flow path is 0, if be 0, then current transmission is the transfer of data newly started.
Wherein, judge that whether current transmission is that the method for the transfer of data newly started in data flow path is not limited to above-mentioned three kinds, can also have other modes, the embodiment of the present invention does not limit.
In another embodiment of the invention, introductory period form of presentation specifically comprises with under type at least one: transmitting continuous time, current transmission integrated flow, transmission rate.
In another embodiment of the invention, before judging whether current transmission is the transfer of data newly started, can also comprise: according to configuration in advance or the definite condition of data flow path that obtains from other network elements, described judgement process is carried out to the data flow path meeting definite condition.
Step 103, within the introductory period, the packet that this data flow path is transmitted to be processed according to preference strategy.
Such as, after step 102 starts the introductory period, within the introductory period, by the current of this data flow path and follow-up data bag, process according to preferential strategy.After exceeding the introductory period, after namely the introductory period expires, to the packet received, can process according to non-preferential strategy.
In another embodiment of the invention, carrying out process according to preference strategy can comprise with under type at least one:
Such as, mode A: priority scheduling is carried out to the packet of described data flow path.
Such as, mode B: select the link of quality higher (such as) to send the packet of described data flow path.
Such as, mode C: carry out priority flag to the packet of described data flow path, makes subsequent module or network element carry out priority treatment to described packet.
Such as, mode D: when congestion packet loss, preferentially abandons the bag of other data flow path.
Such as, mode E: the special decoding method (Codec) that can reduce packet loss, the error rate to the packet application of described user's circulation road.
Wherein, the mode of carrying out processing according to preference strategy is not limited to above-mentioned several, can also have other modes, and such as, re-transmission policy etc., the embodiment of the present invention does not limit.
In another embodiment of the invention, the introductory period can also be made up of the stage with different priorities, namely carries out processing at least two kinds that can comprise above-mentioned processing mode according to preference strategy, such as: mode A and mode D.Therefore, within the introductory period, carry out process to packet according to preference strategy can comprise: according to the priority of described different phase, processes packet in each stage according to different preference strategies.Wherein, in the stage that the time is more forward, priority level is higher, specifically can adopt higher processed, lower drop probability etc.
In another embodiment of the invention, after exceeding the introductory period, after namely the introductory period expires, to the packet that this data flow path is transmitted, can process according to non-preferential strategy; Or process according to punishment strategy, such as, reduce dispatching priority, increase drop probability, the speed etc. of restriction transmission.Wherein, longer for the transmission time, total flow is larger, or the user that speed is larger, and the dynamics that can arrange punishment is larger.
Can draw from above-described embodiment, can give and the process of higher priority an incipient data flow, interaction service and background business can both be indebted to this period of introductory period at initial period.Wherein, because interaction service occurs frequent, and each business duration is short, therefore priority treatment can be enjoyed frequently, and due in the duration that each business is shorter, all or the most of the time all within the introductory period, therefore can enjoy higher and stable speed, data can be completed fast download and result is shown to user, thus improve user satisfaction.And background business continues a few minutes by several hours due to each business, the introductory period only may account for very small scale within the whole business duration, very little to the contribution of the transmission rate and stability that improve whole process; And due to background business each duration long, therefore in the unit interval, business Frequency is more much smaller than interactive class, and each business transmission could enjoy priority treatment when starting, the introductory period number of times that therefore in the unit interval, background business can be enjoyed and duration also fewer than interaction service.
Certainly, the embodiment of the present invention is not limited to the business only using Transmission Control Protocol, those are used to the small data quantity business of udp protocol, as the business such as short message, instant messaging, its business model is several (on a small quantity) business data packet of paroxysmal transmission at set intervals, therefore generally always within the transmission introductory period of data flow path, also priority treatment can be enjoyed, speeding up data transmission, reduces drop probabilities, thus improves user satisfaction.
As shown in Figure 3, the flow chart of a kind of business data processing method that another embodiment of the present invention provides, can comprise following content.
Step 201, network element or terminal receive a packet of data flow path;
Such as, network element can be the BSS in GPRS/UMTS network, NodeB, eNodeB, RNC, SGSN or GGSN; Or, eNodeB or S-GW/P-GW in EPS network; Or, BTS or ASN-GW in WiMax network; Or, the AP etc. in Wifi network, the network element of transmission user face data.
Network element will transmit the customer traffic of multiple user usually simultaneously, and each user may have one or more customer traffic again.Therefore, by the embodiment of the present invention, can reducing or avoid those to use the user of background business to seize too much bandwidth resources, providing more Internet resources for using the user of interactive service.
In different networks, the granularity of the data flow path that network element can control may be different.Such as: in xDSL or wlan network, network is that each terminal (user) only provides a data flow path, the inner fine granularity passage no longer distinguishing different QoS.The data flow of all business is all transmitted in a data flow path.
And in common mobile, such as GPRS, WiMax, and in EPS network, for the terminal of these network systems, for meeting the qos requirement of different business data flows, support terminal accesses multiple public data network (PDN), or for meeting the reasons such as charging, in user data channel, more fine-grained data flow path may be divided according to APN or QoS etc. parameter.As in EPS network, data flow path according to granularity is from big to small:
1, terminal granularity data circulation road: the i.e. set of all business data flows of a terminal.
2, PDN connects (PDN Connection): terminal is to the set of all business data flows of a PDN.
3, (Bearer) is carried: set terminal with the business data flow of identical qos requirement.Such as, can according to different aggregation strategys, business data flows with identical qos requirement all in terminal can be aggregated in a carrying, also all business data flows with identical qos requirement in of a terminal PDN can being connected are aggregated in a carrying, business data flow terminal with identical qos requirement can certainly be aggregated in multiple carrying respectively according to other strategies.
4, business data flow (Service Data Flow): operation layer has a data flow of identical qos requirement, a such as audio stream, or video flowing, usually the parameter information of its IP head is used in an ip network, as source IP address, object IP address, upper-layer protocol type, source port number, destination slogan, TOS/DSCP, FlowLabel etc. (being commonly called as " five-tuple ") describe the feature of a business data flow.
In another embodiment of the invention, a large data flow path can be made up of the data flow path of one or more smaller particle size, and this is called as " polymerization ".Such as several business data flows are aggregated in a carrying, are associated with same PDN and form a PDN with the carrying of IP address of terminal and is connected, and all PDN of terminal connect i.e. formation terminal granularity data circulation road.
Network element or terminal can be closed in above-mentioned varigrained data flow path or channel set as required and be applied the business data processing method of the embodiment of the present invention.Be exemplified below:
-business data processing method to all packet application embodiment of the present invention of terminal granularity data passage.
-business data processing method to the packet application embodiment of the present invention in non-GBR carryings all in terminal granularity data passage.
-to the carrying in terminal granularity data passage with specific QCI, such as QCI=9, the business data processing method of the packet application embodiment of the present invention in the carrying of the Background QoS of corresponding lowest priority.
The business data processing method of the packet application embodiment of the present invention in all non-GBR carrying during the PDN of-certain or some specific APN to terminal, the APN accessed as corresponding internet connects.
-PDN of certain or some specific APN of terminal is connected in there is the business data processing method of the packet application embodiment of the present invention in the carrying of specific QCI.
-to the business data processing method of the data flow application embodiment of the present invention of packet composition that marked specific DSCP in certain carrying of terminal.
-to the business data processing method of the data flow application embodiment of the present invention of packet composition using specific protocol port numbers (as used Transmission Control Protocol, and peer port number is the well-known port number 80 of http protocol) in certain carrying of terminal.
The definite condition of the data flow path of the business data processing method of the application embodiment of the present invention, such as, can be APN (Access Point Name, APN), GBR or non-GBR type (Guaranteed BitRate Services, GBR Services), QCI (Quality Class Identifier, quality of service class identifies), DSCP or FlowLabel etc., can configure on network element, also can be indicated to execution network element by other network element.
Such as in EPS network, in carrying Establishing process, MME can notify the definite condition of eNodeB data flow path, which current data flow path of eNodeB is indicated to need to apply the business data processing method of the embodiment of the present invention, eNodeB obtains the definite condition of data flow path, to the business data processing method of the data flow path application embodiment of the present invention meeting this definite condition, when judging that current transmission is the transfer of data newly started, start introductory period processing procedure, and within the introductory period, the packet that this data flow path is transmitted is processed according to preference strategy.
Again such as, in EPS network, in packet repeating process, S-GW/P-GW filters downlink data packet, the Packet Filtering of certain condition (such as by the business of operator's not perception or type of service) will be met out, stamp special DSCP or FlowLabel mark, eNodeB is configured with, or indicated by other network elements, by a kind of terminal, or a PDN connects, or transmit in a carrying, the packet with special DSCP or FlowLabel is considered as belonging to a data flow path, to the packet transmitted in this data channel, when judging that current transmission is the transfer of data newly started, start introductory period processing procedure, and within the introductory period, the packet that this data flow path is transmitted is processed according to preference strategy.
Usually a terminal (i.e. a main frame) is regarded as a user, a terminal may run multiple business simultaneously, namely may transmit multiple business data flow simultaneously, both interactive service may be had in these business, also may to have powerful connections formula business, pass through the embodiment of the present invention, can when the interactive service of user and background business coexist, reduce or avoid the background business in this terminal to seize too much bandwidth resources, save Internet resources, and provide better Internet resources and Consumer's Experience for interaction service.
In an alternative embodiment of the invention, each business data flow is when business is set up, (the socket module as ICP/IP protocol stack in terminal) flow filter can be set up in the communication module of terminal, this flow filter comprises IP " five-tuple " information (as source IP address, object IP address, protocol type, source port number, destination slogan, DSCP, FlowLabel etc.) of corresponding Business Stream.When business module in terminal will send data, packet is delivered to the communication module of terminal downwards, packet mates with multiple flow filter that it is set up by communication module successively, after the match is successful with certain flow filter, just think that this packet belongs to this business data flow, namely the data flow path in terminal refers to for transmitting the logical channel that certain business data flow is safeguarded and the data structure of being correlated with.Such as, run an interactive service and a background business in terminal simultaneously, then can set up respectively in the communication module of terminal to should interactive service data stream flow filter and to should the flow filter of background business, namely safeguard the data flow path of the data flow of corresponding two business respectively.
The time interval of the adjacent upper packet transmitted in the data flow path recorded in the time that step 202, network element or terminal are more current and data flow path context.
If the interval time of the adjacent upper packet transmitted in the time of advent of current data packet and data flow path exceedes threshold value, then enter step 203, otherwise enter step 205.
Such as, TCP is connected, under normal circumstances, in the RTT time, has a data packet transmission at least, if within continuous several RTT cycle, all without any data packet transmission in connection, then can think the last business end of transmission on connecting.Therefore the threshold value value in the time interval can be the several times of RTT empirical value, on network the RTT cycle generally tens to hundreds of millisecond, several RTT cycle, the chances are several seconds long, such as 2-5 second.
Within a RTT cycle, generally 1 packet respectively can be had at least in each direction owing to adopting the application program of Transmission Control Protocol, network element or terminal can distinguish the time of advent of an adjacent upper up and downlink data packet in record data circulation road, relatively time, current data packet is reached the time with equidirectional adjacent on time of advent of a packet compare; Also can not distinguish direction only to record a unified adjacent upper packet and reach the time.
In another embodiment of the invention, if data flow path is just set up, such as, to a newly-established carrying, or the wireless access part (RAB) of carrying is just recovered.Current data packet is first packet of transmission in data flow path, then can think very long with the time interval of a upper packet in this case, be greater than threshold value.
In another embodiment of the invention, also can according to the flow of accumulation transmission of nearest a period of time (as in several seconds), or the mode such as speed judges the time interval with an adjacent upper packet.Such as, in nearest several seconds, accumulative delivery flow rate is 0, or transmission rate is 0, then can judge to be greater than threshold value with the time of advent of an adjacent upper packet.
Step 203, network element or terminal start priority treatment to the packet transmitted in this data flow path, namely start the introductory period, can also arrange introductory period mark.
Be in the introductory period if this subscriber channel is current, then restart the introductory period.
The information of introductory period start-up point in network element or this data flow path of terminal record, as the timestamp of Startup time, and determine introductory period termination condition, introductory period form of presentation specifically comprises with under type at least one: transmitting continuous time, current transmission integrated flow, transmission rate, or the combination of above-mentioned parameter.
When the introductory period was stated by transmitting continuous time, then need to record the timestamp of introductory period when starting, when after the transmission of this data flow starts in certain hour length, as 15 seconds, for being in the introductory period;
When the introductory period is stated by current transmission integrated flow, need integrated flow in introductory period last time in the data flow path of statistics to reset when each startup introductory period, restart statistics, when in data flow path, this accumulative delivery flow rate does not exceed certain traffic threshold, as 500KBytes, for being in the introductory period;
When the introductory period is stated by transmission rate, when the speed of this data flow promote do not reach given pace thresholding time, as 128Kbits/ second, for being in the introductory period.
In another embodiment of the invention, the introductory period can also adopt the combination of above-mentioned parameter to state, and such as after meeting in following 3 conditions any one, this introductory period terminates: 1) introductory period start after be continued above 15 seconds; 2) add up to transmit 500K Bytes data in passage after the startup of this introductory period; 3) this introductory period start after the transmission rate of passage reached more than 128Kbits/ second.
In another embodiment of the invention, before can also starting according to this data transfer, in data flow path, the length of free time decides the length of introductory period, if in data flow path, free time is longer before, then this introductory period gives the time span more grown, or accumulative delivery flow rate thresholding, etc.
Step 204, packet to be processed according to preference strategy.
Priority treatment can to shorten the RTT of data flow, and the packet loss (comprising Packet Error Rate) reducing data flow realizes for main target.After having processed, step 209 can be performed: terminate the process to packet.
Shorten the RTT of data flow, both can accelerate slow start stage and complete, and make interactive service can reach higher speed fast, in the fixed-size situation of receive window that can connect at TCP again, the transmission rate that TCP can obtain is higher.The appearance of the situation that the packet loss reducing data flow then can prevent speed from sharply reducing.
In another embodiment of the invention, can according to different network QoS mechanism, the ability of network element or terminal, network element or terminal can adopt following different priority treatment strategy to process.
Such as, mode A: priority scheduling is carried out to the packet of described data flow path.Priority scheduling is namely preferential sends the higher packet of priority, makes the quality of the data flow of business obtain higher guarantee.
Such as, mode B: select the higher link of QoS to send the packet of described data flow path.QoS is higher, refers in current link, selects the link that a QoS is higher.The link that QoS is higher is selected to send packet (such as in current link, QoS from large to lower in arrangement front 40% link, the link that QoS is higher can be thought), then priority ratio can be sent higher, or link-quality is good, packet loss is low, the error rate is low, thus the quality of the data of business can be made to obtain higher guarantee.
Such as, mode C: can apply the packet of described user's circulation road and reduce packet loss, the special decoding method (Codec) of the error rate or re-transmission policy.
Such as, mode D: carry out priority flag to the packet of described data flow path, such as, stamp the modes such as the TOS/DSCP of corresponding high priority processing policy, make subsequent treatment module and follow-up network element carry out priority treatment to described packet at IP head.After carrying out priority flag, follow-up receive this packet module or after network element resolves mark, according to same preference strategy, packet can be processed, such as described priority scheduling, higher link, reduces the process of packet loss etc.
Such as, mode E: when congestion packet loss, preferentially abandons the bag of other data flow path; Namely reduce or avoid the packet loss of described data flow path.
In another embodiment of the invention, classification can also be carried out according to the duration of this data transfer to the priority treatment strategy of the data flow path being in the introductory period, such as; The whole introductory period is 15 seconds (or accumulation 500K Bytes), but for 5 seconds (or starting 200K Bytes) that transmission starts, give higher priority policy, if (or 200K Bytes) transmission does not terminate in 5 seconds, in 10 below second (or 300K Bytes), give and the priority policy slightly lower than beginning 5 seconds, but still higher than the priority higher than common process strategy.
If step 205 step 202 judge adjacent in current time and data flow path on the interval of the time of advent of a packet be less than threshold value, then judge that the introductory period of this data flow path current marks whether to arrange.If so, then enter step 206, otherwise enter step 208.
Step 206, judge whether the introductory period of data flow path terminates.
Corresponding step 203, duration since judging the startup of this data flow path introductory period, and/or accumulative delivery flow rate in this introductory period, and/or whether the current transmission rate of data flow path meets the termination condition of introductory period, such as, judge this data flow path introductory period start since duration whether overtime threshold value, in this introductory period, whether accumulative delivery flow rate reaches threshold value, and/or whether the current transmission rate of data flow path reaches threshold value.If meet introductory period termination condition, then enter step 207, otherwise enter step 204.
The introductory period mark of step 207, the circulation road that clears data, but the duration since minute book data transfer starts can have been continued, integrated flux etc.
Step 208, the processing policy of packet according to non-priority to be processed.
In another embodiment of the invention, when the introductory period adopts time span statement, except the introductory period Startup time recorded in current time and data flow path being compared when packet each above adopting arrives and judging whether the introductory period terminate, can also the modes such as timer be adopted, repeat no more.
In fact degradation process to common discharge is equivalent to the priority treatment of other flow, in addition, owing to have recorded this data transmission start time of data flow path, and integrated flux, therefore to the data flow path transmitted for a long time, network element or terminal can strengthen drop probability and punish it.
Step 209, current data packet process to be terminated.
See Fig. 4, be the network element structural representation that the embodiment of the present invention provides, comprise: a kind of network element 40, comprising: receiving element 401, judging unit 402, processing unit 403,
Receiving element 401, the packet of receiving data stream passage;
