Embodiment
What the invention provides a kind of Ethernet service unaware follows method of testing and device, use this method and apparatus to carry out operational trials and do not take the regular traffic bandwidth, can realize simultaneously real-time monitoring again, promote bandwidth availability ratio, reduce the service operation cost simultaneously network traffics.
The present invention, be subjected to tradition to adopt the token bucket mode business to be carried out the inspiration of bandwidth profile shaping (bandwidth profile), calculate the idle bandwidth of link by first group of token bucket, transmission rate by second group of token bucket control test traffic, idle bandwidth is used for the transmission of test traffic, utilizes new token bucket algorithm to realize real-time monitoring regular traffic speed.Below described in detail by two embodiments respectively.
Execution mode 1.
This execution mode is used for the unaware test of single-rate bandwidth profile shaping (bandwidth profile), realize by two token buckets, promptly first group of token bucket is made up of first token bucket 11, second group of token bucket is made up of second token bucket 12, first token bucket 11 calculates the idle bandwidth of link, the transmission rate of second token bucket, 12 control test traffics is used for idle bandwidth the transmission of test traffic.
Concrete token bucket algorithm such as Fig. 1, Fig. 2 and shown in Figure 3.
At first, first token bucket 11 is full, and promptly the token number in first token bucket 11 equals committed burst size CBS1, and second token bucket 12 is empty.
When traffic frame arrives, this traffic frame is carried out mark according to following condition:
If the current token quantity current token bucket of the first token bucket 11() is more than or equal to the threshold value of first token bucket 11, think that then this business does not surpass committed information rate (CIR), this traffic frame of mark is green bag, be labeled as the token that the traffic frame consumption of green bag equates with this traffic frame frame length, that is, this moment first token bucket 11 the frame length of token number-this traffic frame of current token quantity=its previous moment.
If the current token quantity of first token bucket 11 less than threshold value, thinks that then this business has surpassed CIR, be labeled as red packet, the traffic frame that is labeled as red packet does not consume token, that is, this moment first token bucket 11 the token number of current token quantity=its previous moment.
When refreshing of CIR arrived constantly, the current token quantity of first token bucket 11 and second token bucket 12 was upgraded in the following manner:
If the current token quantity of first token bucket 11 is greater than the committed burst size CBS1 of first token bucket 11, the current token quantity=CBS1 of first token bucket 11 then, unnecessary token is sent to second token bucket, token number+the CIR of current token quantity=its previous moment of second token bucket 12 refreshes the token number, wherein, CIR refreshes the token number and is calculated by CIR;
If the current token quantity of first token bucket 11 is smaller or equal to CBS1, then token number+the CIR of current token quantity=its previous moment of first token bucket 11 refreshes the token number, the token number of current token quantity=its previous moment of second token bucket.
As depicted in figs. 1 and 2, if the Mean Speed＜CIR of traffic frame, then the token in first token bucket 11 accumulates, but if the token number≤CBS1 in first token bucket 11, second token bucket 12 just is empty; Because the Mean Speed＜CIR of traffic frame, the phenomenon that the token of first token bucket 11 finally will occur overflowing, the token that overflows is just being represented idle bandwidth, and idle bandwidth can be distributed to test service and use, and this token that just means that first token bucket 11 overflows will be delivered in second token bucket 12.
As shown in Figure 3, when first token bucket 11 is filled token, unnecessary token is sent to second token bucket 12, when the current token quantity of second token bucket 12 begins to send test frame during greater than its threshold value, so, the token number of the current token quantity=previous moment of second token bucket 12-test frame frame length; When the current token quantity of second token bucket 12 stops to send test frame during smaller or equal to its threshold value.
Execution mode 2.
This execution mode is used for the unaware test of dual rate bandwidth profile shaping (bandwidth profile), the difference of this execution mode and execution mode 1 is to be realized by three token buckets, promptly first group of token bucket is made up of first token bucket 11 and the 3rd token bucket 13, second group of token bucket is made up of second token bucket 12, first token bucket 11 and the 3rd token bucket 13 be associated the idle bandwidth of outgoing link, the transmission rate of second token bucket, 12 control test traffics is used for idle bandwidth the transmission of test traffic.
Specific algorithm is as follows:
At first, first token bucket 11 is full, and promptly token number equals CBS1, and the 3rd token bucket 13 also is full, and promptly token number equals extreme burst amount EBS1, and second token bucket 12 is empty.
When traffic frame arrives, according to the described traffic frame of following condition flag:
If the current token quantity of first token bucket 11 is more than or equal to the threshold value of first token bucket 11, think that then this business does not have CIR, this traffic frame of mark is green bag, the traffic frame that is labeled as green bag consumes the token that equates with its frame length in first token bucket 11, promptly, token number-the frame length of current token quantity=its previous moment of first token bucket 11, the token number of current token quantity=its previous moment of the 3rd token bucket 13;
If the current token quantity of first token bucket 11 is less than the threshold value of first token bucket 11, and the current token quantity of the 3rd token bucket 13 is more than or equal to the threshold value of the 3rd token bucket 13, think that then this business is not surpass peak information rate (EIR), this bag can be served as much as possible, this traffic frame of mark is yellow bag, and the traffic frame that is labeled as yellow bag consumes the token that equates with its frame length in the 3rd token bucket 13;
If the current token quantity of first token bucket 11 is less than the threshold value of first token bucket 11, and the current token quantity of the 3rd token bucket 13 is less than the threshold value of the 3rd token bucket 13, think that then this business has surpassed EIR, generally abandon, there is the network of bearing capacity also can be served as much as possible, this traffic frame of mark is a red packet, the traffic frame that is labeled as red packet does not consume token, that is the token number of current token quantity=its previous moment of first token bucket 11, second token bucket 12 and the 3rd token bucket 13.
When refreshing of CIR arrives constantly:
Token number+the CIR of current token quantity=its previous moment of first token bucket 11 refreshes the token number, and CIR refreshes the token number and calculated by CIR;
When peak information rate EIR refreshes when constantly arriving, the token number+EIR of current token quantity=its previous moment of the 3rd token bucket 13 refreshes the token number, and EIR refreshes the token number and calculated by EIR.
As shown in Figure 4, when the Mean Speed of traffic frame＜CIR, the token in first token bucket 11 accumulates, but if the token number≤CBS1 in first token bucket 11, second token bucket 12 just be a sky;
When first token bucket 11 is filled token, if the coupling mark CF (coupling flag) of first token bucket 11 and the 3rd token bucket 13 mainly is a token in related first token bucket 11 and the 3rd token bucket 13 for the value of 1(CF, be used to control the quantity of yellow bag, decision when the first token bucket l1 is full unnecessary token whether be sent to the 3rd token bucket l3), so unnecessary token is sent to the 3rd token bucket 13, when the 3rd token bucket 13 was expired, unnecessary token was sent to second token bucket 12; If CF=0, the unnecessary token of the first token bucket l1 will directly be sent to second token bucket 12 so, and when token bucket l3 was full, unnecessary token also was sent to second token bucket; Like this, if the Mean Speed≤CIR of traffic frame, the phenomenon that the token of first token bucket 11 finally will occur overflowing, the token that overflows is just being represented idle bandwidth, idle bandwidth can be distributed to test service and use, and this just means that the token that overflows delivers in second token bucket 12 the most at last.
If the Mean Speed＞CIR of EIR 〉=traffic frame, the then token of the 3rd token bucket 13 phenomenon that the most can not occur overflowing.
When CIR refreshes when constantly arriving:
If the token number＞CBS1 of first token bucket 11 then makes the token number=CBS1 in first token bucket 11;
If CF=1,
Then, the token number of current token number=its previous moment of the 3rd token bucket 13+first token bucket 11 refreshes the token number;
The token number of current token number=its previous moment of second token bucket 12.
If CF=0,
Then, the token number of current token number=its previous moment of the 3rd token bucket 13;
The CIR of the token number of current token number=its previous moment of second token bucket 12+first token bucket 11 refreshes the token number.
If the token number≤CBS1 of first token bucket 11,
The CIR of token number+first token bucket 11 of current token quantity=its previous moment in first token bucket 11 refreshes the token number;
The token number of the token number of the 3rd token bucket 13=its previous moment;
The token number of the token number of second token bucket 12=its previous moment;
When refreshing of EIR arrives constantly:
If the token number＞EBS1 of the 3rd token bucket 13, then,
Token number=EBS1 in the 3rd token bucket 13;
The EIR of the token number of current token number=its previous moment of second token bucket 12+the 3rd token bucket 13 refreshes the token number;
If the token number≤EBS1 of the 3rd token bucket 13, then,
The EIR of token number+the 3rd token bucket 13 of the token number in current the 3rd token bucket 13=first token bucket, 11 previous moment refreshes the token number
The token number of the token number of second token bucket 12=its previous moment.
As shown in Figure 5, when the token in first token bucket 11 overflows, if CF=1 just is sent to unnecessary token the 3rd token bucket 13, if CF=0 then is sent to second token bucket 12; When first token bucket 11 and the 3rd token bucket 13 all overflow, unnecessary token all will be sent to second token bucket 12.
As shown in Figure 6:
When the token number of second token bucket 12＞second token bucket, 12 threshold values, begin to send test frame, this moment second token bucket 12 the token number-test frame frame length of token number=its previous moment;
When the threshold value of token number≤second token bucket 12 of second token bucket 12, stop to send test frame.
The present invention, dynamically adjust the bandwidth profile of general traffics according to the real-time bandwidth of regular traffic, for example, to the UNI inlet of certain metropolitan area network, certain EVC passage carries out the speed that professional unaware is followed test service, rationally use idle bandwidth, improve the utilance of line bandwidth, also can realize the bandwidth profile to general traffics simultaneously, UNI can see a pipeline, EVC is exactly small tubes in the pipeline, and CIR/EIR can regard the diameter of EVC pipe as.
Concrete application 1: based on the unaware test of single-rate bandwidth profile.
Setting CIR is 400Mbps.
This EVC channel rate diameter has only 400Mbps, but the arrival burst rate maximum of traffic frame can reach 1000Mbps, as shown in Figure 7, belong to this EVC traffic frame＜400Mbps green bag (can provide performance guarantee traffic frame) will be provided, the traffic frame of 〉=400Mbps will be labeled as red packet (not having the traffic frame that any performance guarantees), and red packet often is defined as and abandons.
When the traffic frame speed that belongs to this EVC＜400Mbps, the token of first token bucket 11 adds the fast of specific consumption, continue to be added to overflow and deliver to second token bucket 12, the token number that second token bucket 12 obtains will send the test frame that belongs to this EVC during greater than its threshold value accordingly, test frame with the speed polishing of EVC passage to 400Mbps; When traffic frame 〉=400Mbps, it is fast that the token consumption rate of first token bucket 11 adds, and token will reduce to below the threshold value, second token bucket 12 can not get any token, do not have test frame to send, the EVC channel rate remains 400Mbps, and final test effect as shown in Figure 7.
Concrete application 2: based on the unaware test of dual rate bandwidth profile.
Setting EIR is 500Mbps, and CIR is 400Mbps.
This EVC channel rate diameter is 500Mbps to the maximum, but the arrival burst rate maximum of traffic frame can reach 1000Mbps, as shown in Figure 8, belongs to traffic frame＜400Mbps of this EVC, will be marked as green bag, and these business must provide performance to guarantee; 〉=400Mbps but＜traffic frame of 500Mbps will be labeled as yellow bag, this part business is that the performance that provides of doing one's best guarantees; The traffic frame of 〉=500Mbps will be labeled as red packet, and this part business is that no any performance guarantees.
When the traffic frame speed that belongs to this EVC＜400Mbps, the token of first token bucket 11 adds the fast of specific consumption, continues to be added to and overflows, if CF=1, unnecessary token is given the 3rd token bucket 13, the three token buckets 13 and finally also will be overflowed, and unnecessary token is given second token bucket 12; When CF=0, unnecessary token directly give second token bucket token number that 12, the second token buckets 12 obtain greater than threshold value, will send the test frame that belongs to this EVC accordingly, test frame with the speed polishing of EVC passage to 500Mbps; As traffic frame 〉=400Mbps but＜500Mbps, it is fast that the token consumption rate of first token bucket 11 adds, token will reduce to below the threshold value, at this moment will consume the token of the 3rd token bucket 13, but the 3rd token bucket 13 adds the fast of specific consumption, continues to be added to and overflows when giving second token bucket token number that 12, the second token buckets 12 obtain greater than threshold value, can corresponding send the test frame that belongs to this EVC, test frame with the speed polishing of EVC passage to 500Mbps; When traffic frame 〉=500Mbps, it is fast that the token consumption rate of first token bucket 11, the 3rd token bucket 13 adds, and token will reduce to below the threshold value, second token bucket 12 can not get any token, do not have test frame to send, the EVC channel rate remains 500Mbp, and final test effect as shown in Figure 8.
In such scheme, EVC passage bandwidth availability ratio at any time all can reach 100%, the test traffic bandwidth is dynamically adjusted according to service bandwidth: whole transport services when service bandwidth takes, and test transmission business when business has the space is all distributed to test service and is used when not having business; Whole network architecture does not increase any new hardware, interface or equipment for monitor network performance and quality.
