Specific embodiment

It is with reference to the accompanying drawings and embodiments, right in order to which the objects, technical solutions and advantages of the application are more clearly understood The application is further elaborated.It should be appreciated that specific embodiment described herein is only used to explain the application, not For limiting the application.

It should be noted that unless otherwise defined, all technical and scientific terms used herein and belong to this hair The normally understood meaning of bright those skilled in the art is identical.Term as used herein in the specification of the present invention It is intended merely to describe the purpose of specifically embodiment, it is not intended that in the limitation present invention.Term as used herein "and/or" Including any and all combinations of one or more related listed items.

In access net and transmission network, communication equipment such as router, interchanger or other equipment serve as business datum remittance The Bandwidth Management of the poly- node with distribution, communication equipment is rather important for promoting service feature end to end.As shown in Figure 1 It is the logical construction block diagram of double leaky buckets in communication equipment, wherein dotted arrow line indicates one of data flow distribution path, respectively CBS barrels PCP (Priority Code Point, priority code point) priority is different, each EBS same PCP priority Also different.The different PCP priority of leaky bucket correspond in the service traffics formed when business data transmission, each data flow PCP priority.After distribution of traffic flows module comes data stream distribution, data flow obtains token from corresponding leaky bucket and obtains Normally to forward, to achieve the purpose that broadband manages.Different broadband management methods, effect achieved can then differ widely.

Inefficient problem, broadband provided by the present application are managed for the broadband in the presence of Conventional wide band way to manage Management method can be applied in application environment as shown in Figure 1.In a communications device, the module for being responsible for traffic monitoring obtains industry Be engaged in after flow, according to the default shared model between the priority of service traffics and CBS barrels and EBS barrels, to service traffics into Row traffic monitoring and label are handled.Hereafter, the module for being responsible for traffic shaping can be according to flowexit total bandwidth and mark Reason as a result, carrying out traffic shaping processing, the bandwidth of limit service flow to traffic monitoring and label treated service traffics. In this way, improving the fining degree of traffic monitoring and Shape correction, achieve the purpose that improve the broadband efficiency of management.

Referring to Fig. 2, in one embodiment, a kind of broadband management method is provided, to be applied to application shown in FIG. 1 For environment, include the following steps S12 to S16:

S12 obtains service traffics.

It is appreciated that after service traffics enter communication equipment, it will by traffic classification handle, by service traffics not Data flow (or Business Stream) with type of service is sorted out respectively.In other words the service traffics of above-mentioned acquisition are through inflow-rate of water turbine point Class treated service traffics.The traffic classification of service traffics is realized by the traditional traffic classification processing in this field.

Specifically, in a communications device, the Business Stream that traffic monitoring module can be exported by receiving flow categorization module The mode of amount directly or indirectly obtains sorted service traffics.In sorted service traffics, each data for being included Stream is corresponding with different data priorities respectively, can there is different colors with correspondence markings, as being used to mark and preferentially forward First color and for marking the second color preferentially abandoned.

S14, according to the default shared model between the priority of service traffics and CBS barrels and EBS barrels, to Business Stream Amount carries out traffic monitoring and label is handled.

It is appreciated that the priority of service traffics refers in service traffics, the respectively corresponded difference of each data flow for including Data priority.The high priority data for each stream identification in service traffics that be such as, but not limited to after traffic classification be respectively Grade, or the pre-set priority list by inquiring each data flow (have such as pre-established different types of data flow and each number According to the list of the corresponding relationship between priority), the corresponding data priority of each data flow determined.

Default shared model refers to that data flow shares usage mode according to predetermined double leaky buckets, in CBS barrels and EBS barrels Current and marker color processing mode between both leaky buckets.Default shared model can be according to the net in practical application scene Network environment is previously set, if can ensure with user it is matched it is end-to-end between service traffics message transmission rate i.e. It can.Wherein, in label treated service traffics, each data flow can be marked as the data flow of three kinds of colors, i.e., labeled as the The data flow of one color, the data flow labeled as the second color and the data flow labeled as third color.CBS barrels namely storage The leaky bucket of first color token, EBS barrels namely store the second color token leaky bucket.First color, the second color and third face Color is such as, but not limited to the green, yellow and red arranged in traditional technology respectively, as long as it is preferential to be respectively used to difference It forwards data, preferential discarding data and abandons data immediately.

Specifically, the priority that can be carried according to data flow each in service traffics controls industry according to default shared model Flow be engaged in by CBS barrels and EBS barrels, makes each data flow of service traffics respectively from CBS barrels or EBS barrels acquirement token passings, or Person does not obtain token and is dropped, that is, completes to carry out traffic monitoring, and complete color mark when each data flow obtains token.When When data flow obtains the first color token, that is, it is marked as the first color (ensureing speed data), belongs to and ensures Business Stream, is needed preferential Forwarding.When data flow obtains the second color token, that is, it is marked as the second color (excess permission speed data), belonged to preferential The Business Stream of discarding, for preferentially being abandoned when congestion occurs.It is when data flow fails to obtain the second color token, i.e., labeled For red (hypervelocity rate abandons data) color, need to be abandoned immediately in traffic monitoring and label processing links, without being transferred to stream Measure Shape correction link.

Period, CBS barrels can share use with EBS barrels, such as: do not meet the data flow labeled as the first color, it can According to CBS barrels of Couple Flag (connection mark, for selecting the connection type of CBS barrels of overflow channels, with determination be with together The EBS bucket connection of priority also or with the CBS of low priority bucket is connect) determine that the data flow goes to obtain low priority The token of CBS still removes the token for obtaining the EBS bucket of same priority.The first minimum color data stream of priority (namely flow In sorted service traffics, original carries the data flow of the first color mark), fail the order for obtaining the CBS bucket of current priority It, can (overflow channel of the CBS bucket for defining lowest priority be to connect a certain height according to global Couple Flag when board The EBS bucket of priority, also or connection abandons channel) determine it is the token for obtaining the EBS bucket of highest priority, it still goes to obtain Take the token of the EBS bucket of same priority.Do not meet the data flow labeled as the second color, it can be according to EBS barrels of Couple Flag come determine be obtain low priority EBS bucket token, be still marked as third color.

S16, according to flowexit total bandwidth and label processing as a result, to traffic monitoring and label treated Business Stream Amount carries out traffic shaping processing, the bandwidth of limit service flow.

It is appreciated that flowexit total bandwidth refers to the limitation bandwidth of communication equipment output interface, for limiting different numbers The triggering of the amount of bandwidth and congestion avoidance mechanism that are fitted on according to flow point.The result of label processing refers to each number in service traffics Color on being labeled respectively according to stream.

Specifically, limited bandwidth resources in practical applications, and bandwidth needed for different Business Streams is different, ensures preferential Grade is also different, it is therefore desirable to ensure the bandwidth allocation between the Business Stream of different priorities by traffic shaping.It completes to flow After amount monitoring and label, it can in traffic shaping treatment process, according to the color of label, by each data flow, heap enters not respectively It is sent in the shaping queue of same priority, the total bandwidth for limiting data flow is no more than flowexit total bandwidth, ensures Gao You The data flow of first grade is preferentially sent simultaneously, can effectively trigger Congestion Avoidance processing.

Above-mentioned broadband management method, for traffic classification treated service traffics, by according to the preferential of service traffics Grade, and based on the default shared model between CBS barrels and EBS barrels, allow each data flow of service traffics multiple excellent It flexibly shares and splits between the CBS bucket of first grade and EBS barrels, it is finer to the monitoring and label of service traffics.In this way, can base The traffic monitoring that can flexibly share in double leaky buckets and traffic shaping improve the fining degree of traffic monitoring and Shape correction, reach To the purpose for improving the broadband efficiency of management, and application scenarios covering is wider.

Fig. 3 and Fig. 4 are please referred to, in one embodiment, about above-mentioned step S14, can specifically include following processing Step S142 to S150:

S142 sorts out each data flow according to the PCP priority and loss priority of data flow each in service traffics respectively To the CBS bucket of each respective priority and EBS barrels；Wherein, the data flow that loss priority is 0 is sorted out to corresponding PCP priority CBS barrels, the data flow that loss priority is 1 is sorted out to the EBS bucket of corresponding PCP priority.

It is appreciated that loss priority refers to DEI (Drop Eligible Indicator deletes qualified index) field, Its value is 0 or 1.DEI=1 indicates that identified corresponding message (or corresponding data stream) is preferential dropping packets.It is empty in Fig. 4 Line indicate data flow from distribution of traffic flows module come out after, sort out respectively to EBS barrels each.

Specifically, double leaky buckets during the work time can be there are two types of operating mode: colour blindness mode and Se Min mode.Wherein, The color of the original carrying of data flow will be ignored under colour blindness mode, the face of the original carrying of data flow can be then considered under the quick mode of color Color.Different data streams can be corresponding to sort out to the CBS bucket or EBS of identical PCP priority according to self-contained PCP priority Bucket, therefore, under the quick mode of color, data flow is sorted out to still EBS barrels of CBS bucket of identical PCP priority, can be carried by it Priming color namely loss priority determine.The data flow that loss priority is 0 is the first color data stream, therefore, can be with Sort out to the CBS bucket of identical PCP priority；The data flow that loss priority is 1 is the second color data stream, therefore, Ke Yigui Class to identical PCP priority EBS bucket.Each CBS barrels and each EBS barrels of data flow are separately flowed into, if CBS barrels and EBS barrels respective The rate of data flow is less than the rate that data flow flows into clearance bucket, then the data flow flowed into will be gradually accumulated in bucket.

The data flow of spilling is included into the EBS of same PCP priority when any CBS barrels of data flow piles with spilling by S144 Bucket；

The data flow of spilling is included into lower PCP priority when any EBS barrels of data flow piles with spilling by S146 CBS barrels；

It is appreciated that according to preset shared model, the data flow in any one CBS barrels is piled with when overflowing, The Data flow direction of Control strain continues to accumulate with the EBS bucket of PCP priority in EBS barrels.Correspondingly, in any one EBS Data flow in bucket piles with when overflowing, the CBS bucket of the lower PCP priority of the Data flow direction of Control strain, in EBS barrels Continue to accumulate, as shown in figure 4, so that data flow shares CBS barrels and EBS barrels, so that it is guaranteed that the more efficient management in broadband.

S148, by the CBS barrels of data flow tokens with the clearance of CIR rate for the first color, and by EBS barrels with EIR rate The data flow token of clearance is the second color；

The data flow token of spilling is the when the data flow of the EBS bucket of minimum PCP priority piles with spilling by S150 Three colors；Direct discard processing is used for labeled as the data flow of third color.

It is appreciated that each CBS barrel with it is EBS barrels each in, CBS barrels with CIR rate (Committed Information Rate, committed information rate) data flow in clearance bucket, the data flow being cleared also is the first face for smoothly obtaining CBS barrels The data flow of color ream board, therefore being re-flagged color after outflow is the first color, i.e. DEI=0, to identify the data flow For the data flow that need to preferentially forward.EBS barrels are then put with EIR rate (Excess Information Rate, additional information rate) Data flow in row bucket, the data flow being cleared also are the data flow of smoothly the second color token of EBS barrels of acquirement, therefore It is the second color that color is re-flagged after outflow, i.e. DEI=1 need to preferentially be lost when congestion occurs with identifying the data flow The data flow of abandoning.

According to aforementioned preset shared model, when the data flow of the EBS bucket of minimum PCP priority is piled with and is overflowed, Then needing to re-flag the data flow of the spilling color is third color, as shown in figure 4, will be subsequent to identify the data flow It is directly abandoned by traffic monitoring module, without flowing to traffic shaping module.Wherein, X indicates the third for needing to abandon immediately Color data stream.Since in default shared model above-mentioned, the data flow of CBS barrels of spillings is the PCP priority flow according to itself Enter the EBS bucket of identical PCP priority；The data flow that the EBS bucket of not least PCP priority overflows is preferential according to the PCP of itself Grade flows into the CBS bucket of lower PCP priority, namely be on the whole according to shared CBS barrels of the high to Low sequence of PCP priority with EBS barrels, therefore, aforementioned preset shared model in the present embodiment, the priority being referred to as under the quick mode of color is shared Mode.

S142 to S150 through the above steps may be implemented under the quick mode of color, based on the shared double leaky buckets of priority Traffic monitoring scheme is cut from QoS (Quality of Service, service quality) power level and two dimensions of flow two-stage guarantee Enter, realizes the traffic management of more various dimensions；By practice have shown that the service traffics under the mode after traffic monitoring subsequent Traffic shaping processing in, higher to the management fine degree in broadband, the efficiency of management is increased dramatically.

Fig. 5 and Fig. 6 are please referred to, in one embodiment, about above-mentioned step S14, or can specifically include as follows Processing step S141 to S149:

S141 sorts out each data flow according to the PCP priority and loss priority of data flow each in service traffics respectively To the CBS bucket of each respective priority and EBS barrels；Wherein, the data flow that loss priority is 0 is sorted out to corresponding PCP priority CBS barrels, the data flow that loss priority is 1 is sorted out to the EBS bucket of corresponding PCP priority.

It is appreciated that PCP priority, loss priority involved in the present embodiment and other technical terms, To understand referring to the corresponding description of the priority shared model under the quick mode of color in previous embodiment, it is not repeated to go to live in the household of one's in-laws on getting married herein It states.Specifically, double leaky buckets are still work under the quick mode of color in the present embodiment, the primitive color that each data flow carries is considered Come separately flow into each respective priority CBS bucket and EBS barrels.

The data flow of spilling is included into lower PCP priority when any CBS barrels of data flow piles with spilling by S143 CBS barrels, and when the data flow of the CBS bucket of minimum PCP priority piles with spilling, it is excellent that the data flow of spilling is included into highest PCP The EBS bucket of first grade；

The data flow of spilling is included into lower PCP priority when any EBS barrels of data flow piles with spilling by S145 EBS barrels.

It is appreciated that according to preset shared model, the data flow in any one CBS barrels is piled with when overflowing, The CBS bucket of the lower PCP priority of the Data flow direction of Control strain.Hair is piled in the data flow of the CBS bucket of minimum PCP priority When raw spilling, the EBS bucket of the Data flow direction highest PCP priority of Control strain, as shown in Figure 6.Correspondingly, at any one Data flow in EBS barrels piles with when overflowing, the EBS bucket of the lower PCP priority of the Data flow direction of Control strain, so that number Shared CBS barrels and EBS barrels according to stream, so that it is guaranteed that the more efficient management in broadband.Dotted line indicates data flow from distribution of traffic flows in Fig. 6 After module comes out, sort out respectively to EBS barrels each.

S147, by the CBS barrels of data flow tokens with the clearance of CIR rate for the first color, and by EBS barrels with EIR rate The data flow token of clearance is the second color；

The data flow token of spilling is the when the data flow of the EBS bucket of minimum PCP priority piles with spilling by S149 Three colors；Direct discard processing is used for labeled as the data flow of third color.

It is appreciated that each CBS barrel with it is EBS barrels each in, CBS barrels, with the data flow in CIR rate clearance bucket, are cleared Data flow is also the data flow of smoothly the first color token of CBS barrels of acquirement, therefore is re-flagged color after outflow It is the data flow that need to preferentially forward to identify the data flow for the first color, i.e. DEI=0.EBS barrels then with EIR rate clearance bucket Interior data flow, the data flow being cleared also are the data flow of smoothly the second color token of EBS barrels of acquirement, therefore are flowing out Being re-flagged color afterwards is the second color, i.e. DEI=1 need to be abandoned preferentially with identifying when congestion occurs for the data flow Data flow.

According to preset shared model aforementioned in the present embodiment, hair is piled in the data flow of the EBS bucket of minimum PCP priority When raw spilling, then needing to re-flag the data flow of the spilling color is third color, as shown in fig. 6, to identify the data Stream then will abandoned directly by traffic monitoring module, without flowing to traffic shaping module.Wherein, X indicates to need immediately The third color data stream of discarding.Since in default shared model above-mentioned, the data flow of CBS barrels of spillings is according to itself PCP priority flows into the CBS bucket of lower PCP priority, piles with and overflows in the data flow of the CBS bucket of minimum PCP priority When, the data flow of spilling is the EBS bucket that highest PCP priority is flowed into according to the PCP priority of itself.Correspondingly, not least PCP The data flow that the EBS bucket of priority overflows is that the EBS bucket of lower PCP priority namely whole is flowed into according to the PCP priority of itself It is the preferential data flow for ensureing that PCP priority is high on body, CBS barrels and EBS barrels of lower PCP priority is shared, preferentially to ensure height The bandwidth of priority traffic uses.Therefore, aforementioned preset shared model in the present embodiment, is referred to as Se Minmo Priority under formula ensures band preference shared model.

S141 to S149 through the above steps may be implemented under the quick mode of color, based on the shared double leaky buckets of priority Traffic monitoring scheme, divides from more QoS power levels and flow two-stage ensures two dimension incisions, realizes the flowtube of more various dimensions Reason, can be according to actual user's demand, the preferential business transmission for ensureing higher priority user, and broadband management is more fine and poor Alienation is more flexible.By practice have shown that the service traffics under the mode after traffic monitoring are handled in subsequent traffic shaping In, it is higher to the management fine degree in broadband, it can adapt to more application environments, the efficiency of management obtains mentioning by a larger margin It rises.

Please refer to Fig. 7 and Fig. 8, in one embodiment, about above-mentioned step S14, or can specifically include as Lower processing step S14a to S14d:

S14a sorts out each data flow according to the PCP priority and loss priority of data flow each in service traffics respectively To the CBS bucket of each respective priority and EBS barrels；Wherein, the data flow that loss priority is 0 is sorted out to corresponding PCP priority CBS barrels, the data flow that loss priority is 1 is sorted out to the EBS bucket of corresponding PCP priority.

It is appreciated that PCP priority, loss priority involved in the present embodiment and other technical terms, To understand referring to the corresponding description of the priority shared model under the quick mode of color in above-described embodiment, it is not repeated to go to live in the household of one's in-laws on getting married herein It states.Specifically, double leaky buckets are still work under the quick mode of color in the present embodiment, the primitive color that each data flow carries is considered Come separately flow into each respective priority CBS bucket and EBS barrels.

The data flow of spilling is included into the EBS of same PCP priority when any CBS barrels of data flow piles with spilling by S14b Bucket；

Each CBS barrels and it is EBS barrel each in, similarly, CBS barrels with the data flow in CIR rate clearance bucket, after outflow be weighed New marker color is the first color, i.e. DEI=0 is the data flow that need to preferentially forward to identify the data flow.EBS barrels then with EIR Data flow in rate clearance bucket, it is the second color, i.e. DEI=1, to identify the data flow that color is re-flagged after outflow For the data flow that need to be preferentially abandoned when congestion occurs.

Since in the present embodiment default shared model above-mentioned, the data flow of CBS barrels of spillings is preferential according to the PCP of itself Grade flows into the EBS bucket of identical PCP priority, and when any EBS barrels of data flow is piled with and overflowed, the data flow of spilling is direct Labeled as third color.Namely data flow does not share other each the CBS barrels and EBS barrels of lower PCP priority on the whole, with respectively Ensure that the bandwidth of each PCP priority traffic uses on an equal basis.Therefore, aforementioned preset shared model in the present embodiment, The unshared mode being properly termed as under colour blindness mode.

It, can be with the Business Stream of effective guarantee difference PCP priority by above-mentioned processing step S1406 to S1409 Respectively according to the PCP priority height of itself, required broadband service is coequally obtained, the effect of broadband management can be effectively promoted Rate.

Figure 15 is please referred to, in one embodiment, about above-mentioned step S14, or can specifically include following place Manage step:

According to the priority of service traffics, ensure that band preference is shared according to preset priority shared model and priority The mixing shared model of mode composition carries out traffic monitoring to service traffics and label is handled；Wherein, priority shared model with Priority ensures that the proportion between band preference shared model is adjustable.

It is appreciated that priority shared model in this present embodiment and priority guarantee band preference shared model are closed, it can Respectively referring to the corresponding realization in above-described embodiment about the priority shared model under the quick mode of color (or under colour blindness mode) Process ensures band preference shared model similarly to understand, and about the priority under the quick mode of color (or under colour blindness mode) Corresponding realization process similarly understands, is not repeated that expansion repeats herein.Mix shared model namely in service traffics by each During leaky bucket carries out traffic monitoring and label processing, a part of leaky bucket work (or color under the quick mode of color in all leaky buckets Under blind mode) priority shared model, the leaky bucket of remaining part then works under the quick mode of color the excellent of (or under colour blindness mode) First grade ensures band preference shared model.

As shown in figure 15, priority shared model and priority ensure that the proportion between band preference shared model refers to work The leaky bucket for making priority shared model under the quick mode of color (or under colour blindness mode), with work under the quick mode of color (or colour blindness Under mode) priority ensure the ratio between the leaky bucket of band preference shared model, can be according to application environment middle width strip point With option and installment is carried out with the requirement used, as long as the bandwidth allocation and requirement of application request can be ensured, it is ensured that The transmission rate of Business Stream.Therefore, in different application environments, different proportion can be configured, to form difference Mixing shared model, also can configure a greater variety of preset shared models according to application demand.

Specifically, when carrying out traffic monitoring, can also according to the bandwidth allocation and requirement in actual application environment, Traffic monitoring is carried out using mixing shared model and label is handled, and is realized more flexible broadband and is shared, so as to more Efficient management bandwidth, improves applicability.In Figure 15 dotted line indicate data flow from distribution of traffic flows module come out after, sort out respectively To EBS barrels each.

Figure 16 and Figure 17 are please referred to, in one embodiment, about in above-mentioned step S16, according to the total band of flowexit It is wide with label processing as a result, process to treated service traffics the carry out traffic shaping processing of traffic monitoring and label, tool Body may include following processing step S162 and S164:

S162, according to label processing as a result, being joined the team each data flow of service traffics respectively to SP queue and WRR team Column.

It is appreciated that SP (Strict Priority, strict priority) queue namely in queue scheduling, in strict accordance with The order of the priority of label from high to low, the preferential data flow sent in higher priority queues, works as higher priority queues When for sky, the data flow in lower priority queue is retransmited.

WRR (Weighted Round Robin, weighted round-robin scheduling) queue namely refer to using Weight Round Robin side The queue of formula.Each output port can be divided into multiple output queues in scheduling by WRR queue, dispatch of taking turns between individual queue, Guarantee that each queue obtains certain service time.WRR queue can configure weighted value for each queue and (such as be followed successively by W3, w2, w1, w0), weighted value indicates to obtain the specific gravity of broadband resource.Such as the output port of a 100M, the output port is configured The weighted value of WRR queue be respectively 50,30,10,10 (being corresponding in turn in w3, w2, w1, w0), so can guarantee minimum excellent First grade queue at least obtains 10Mbit/s bandwidth.In WRR queue, the scheduling of multiple queues is that repeating query carries out, to each queue It is not fixedly to distribute service time piece: if some queue is sky, changes to next queue scheduling, at once to make full use of band Wide resource.

It, can be with queue type (such as SP of pre-configured shaping queue before the traffic shaping processing of the present embodiment starts Queue and WRR queue two types), configure group weight (such as can need flexible setting SP queue in all teams according to application Accounting in column, so as to WRR queue can press out group weight be weighted poll forwarding), and configuration WRR queue discarding door Limit and discarding weight reach flowexit total bandwidth triggering congestion avoidance mechanism or WRR team for the total flow in data flow Data flow accumulation is more than to abandon partial data stream according to weight is abandoned when abandoning thresholding in column.

Specifically, completing traffic monitoring and label treated to be distinguished after service traffics enter traffic shaping module According to the label of each data flow as a result, joining the team to each SP queue of respective priority and each WRR queue, as shown in figure 17.For example, It is joined the team by the high-priority traffic for re-flagging as the first color to SP queue, preferentially to forward, being re-flagged is first The data flow of the lower priority data flow of color and the second color is then joined the team to WRR queue.Each WRR queue can possess Two subqueues, in each WRR queue, data flow can join the team according to the color of label, such as the data flow of DEI=1 to it In a WRR queue subqueue, the data flow of DEI=0 joins the team to the subqueue of another WRR queue.In this way, can be with logarithm According to stream quickly shunted and convenient for the second color data stream preferential discarding.

S164, it is preferential to forward in SP queue if band needed for SP queue and WRR queue is wider than flowexit total bandwidth Data flow, it is preferential to abandon the data flow that label in WRR queue is color and according to the default discarding weight of WRR queue.

It is appreciated that on a communications device, the flowexit total bandwidth of distribution is predetermined, such as different user choosing The broadband selected is of different sizes, therefore, the flowexit total bandwidth that output port is assigned on the communication equipment that different user uses Also just different, amount of bandwidth is limited.Specifically, on each output port, if SP queue has data flow to carry out output and institute The bandwidth needed is less than the flowexit total bandwidth of the output port, then remaining bandwidth can be used for the scheduling of WRR queue.When SP team Band needed for column and WRR queue is wider than flowexit total bandwidth, and no matter whether WRR queue touches itself discarding door at this time Limit, then will start congestion avoidance mechanism, so that the data in traffic shaping module detect submodule, the number in detection queue When according to stream, the maximum bandwidth for effectively limiting data flow is no more than flowexit total bandwidth.Still the number in SP queue is preferentially forwarded Simultaneously according to stream, it in WRR queue, (namely needs pre-set to lose according to application according to the default discarding weight of WRR queue Abstention weight), preferentially abandon the data flow that label in WRR queue is color, namely DEI=1 in preferential discarding subqueue Data flow.

S162 and S164 through the above steps, can be during data flow exports, the preferential number for ensureing high priority According to the preferential forwarding of stream, the preferential discard processing for abandoning data flow is rapidly completed, improves the efficiency of management in broadband.

It as shown in figure 16, in one embodiment, can also include following processing step after about above-mentioned step S162 Rapid S165 and S166:

S165, if the data flow in WRR queue accumulates the default discarding thresholding more than WRR queue, according to the pre- of WRR queue If abandoning weight, the data flow in random drop WRR queue；

S166 directly abandons the subsequent data flow joined the team if WRR queue takes.

Specifically, joining the team in queuing process in data flow, when the data flow that WRR queue institute energy heap enters has in a period of time Limit, such as in each WRR queue, when the data flow of a certain WRR queue reaches the default thresholding that abandons (namely in configuration WRR The when discarding thresholding that sets of queue) when, start random drop data according to weight is abandoned.

When the WRR queue takes, the data flow of the subsequent WRR queue of joining the team will be simply discarded, to guarantee one In fixed buffering section, the data flow of high-priority queue is abandoned less as far as possible.In practical applications, the length of high-priority queue Can be longer than the length of Low Priority Queuing, and there is a buffer set, therefore, it is ensured that in scheduling, the data of high priority Stream is more ensured.

S165 and S166 through the above steps can be flowed into team's queuing process in quantity, reach that WRR queue is default to lose When abandoning thresholding, the partial data stream of the random drop WRR queue directly abandons the subsequent number joined the team when the WRR queue takes According to stream, the preferential scheduling of joining the team for ensureing high-priority traffic, so as to further improve broadband management fineness with Efficiency.

In one embodiment, about above-mentioned broadband management method, during carrying out traffic monitoring to service traffics, It can choose and the linear speed of data flow is monitored, also can choose and the data rate of data flow is monitored.Linear speed refers to The L1 rate (referring to 1 rate of layer namely physical layer rate, also referred to as end-to-end rate) of data, data rate refer to that the L1 of data is negative The rate (referring to 1 speed under load of layer) of load.Monitoring link L1 rate can help operator effective monitoring VPN (Virtual Private Network) logical The performance indicator (operator promises to undertake to the rate index of user) in road.Data rate is the practical user load speed be benefited of user Rate is the rate index that user is more concerned about, family can be used more to intuitively understand VPN bandwidth shape by monitoring data rate State.There are transformational relations between L1 rate and data rate, and L1 rate is higher than data rate, because data rate has deducted part Heading length metering.In this way, being selected by above-mentioned monitored object, performance monitoring can be effectively carried out, is further increased The broadband efficiency of management.
