Abstract
The invention discloses a method of supporting nested multi METER system structure, which is: 1) in multi METER system, when a packet joins, each targeted METER works concurrently, independently calculating the respective dyeing and token deduction; 2) according to dyeing calculated by each targeted METER, arbitrating according to the following rules, deciding the dyeing of this packet, the rule is: the deep color METER is prior to the light color METER, defined as: red, yellow, green; the METER with priority is prior to the METER without priority; 3) token deduction according to the arbitration of each targeted METER. The method of the invention solves the complex problem of token deduction and supplement in multi METER nesting.
Description
Technical field
The present invention relates to a kind of method of supporting nested many METER system architecture.
Background technology
METER (also claim: meter or measuring appliance) is important function very among the QoS (quality services), in network system, has a very wide range of applications.
The operation principle of single METER, standard has had relevant RFC document to define, and details please refer to RFC4115, RFC2697, RFC2698 etc.In the system of complicacy, often there is the nested problem of multistage METER.Under the nested situation of this multistage METER, the problem of token covering can appear in traditional way.For example: under a simple secondary nested environment; Somely wrap in previous METER and be coloured to yellow and deduct corresponding token number; Be coloured to redness and abandon this bag at a back METER, deducted token number needs covering before the then previous METER, otherwise the flow control inaccuracy; And cover and untimelyly also can go wrong, more multistage nested situation is just more difficult.
Summary of the invention
The technical problem that the present invention will solve provides a kind of method of supporting nested many METER system architecture, and it can solve the challenge of multistage METER in legacy system token deduction and covering when nested.
For solving the problems of the technologies described above, the present invention proposes the method for the nested many METER system architecture of a kind of flexible support, comprising:
1) in many METER system, behind the bag of coming in, each METER concurrent working simultaneously of hitting independently calculates dyeing situation separately, token deduction situation;
2) hit the dyeing situation that METER calculates according to each, make arbitration according to following rule, determine the dyeing situation that this bag is final, rule is: saturate METER has precedence over light-colored METER, and the degree of depth is defined as: redness＞yellow＞green; The METER of band priority has precedence over the METER that is not with priority;
3) above-mentioned each hit METER all according to the arbitration the result carry out the token deduction operation.
The method of many METER system architecture that support of the present invention is nested through adopting arbitration mechanism, can be supported three look METER flexibly, supports multistage nested METER, has well solved the challenge of multistage METER token deduction and covering when nested.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the present invention is done further detailed explanation:
Fig. 1 is a method flow sketch map of the present invention.
Embodiment
The method of many METER framework that support of the present invention is nested proposes a kind of many METER parallel architecture (being that a plurality of METER work simultaneously), METER unitary arbitration and token renewal technology.Method of the present invention is specially (see figure 1): 1) behind the bag of coming in; Each METER that hits (a plurality of METER) concurrent working simultaneously; Independently calculate dyeing situation separately; Token (token) deduction situation, but do not carry out actual dyeing and token deduction operation (promptly only do sign, do not deduct token); 2) then hit the dyeing situation that METER calculates according to each, make arbitration according to following rule, determine the final dyeing of this bag, the rule of arbitration is: saturately have precedence over light-coloredly, the degree of depth is defined as: redness＞yellow＞green; Priority is not with in having precedence over of band priority; 3) each METER all carries out the token deduction operation according to the result of arbitration at last.Said in above-mentioned " hitting " refers to the condition of the triggering METER that satisfies system definition.The method of the dyeing situation of calculating METER is a lot, can adopt the technology in the existing standard, such as RFC4115, RFC2697 or RFC2698 etc.
Arbitration mechanism proposed by the invention is: to certain bag, first judgement can be hit which METER (this determination methods is the industry routine techniques), and these METER that hit all have function of measuring separately, according to the flow of bag, can calculate the color of this bag separately; If have only a METER to hit, the color relation that this METER calculated is the final color of this bag, adopts this METER institute result calculated to carry out the renewal of token; When a plurality of METER hit, if all be not prioritized METER, then the darkest color of color was the color (order of the depth is defined as successively: red＞yellow＞green) of final bag among all METER; If among a plurality of METER that hit prioritized METER is arranged, then the darkest color of color is final bag color among the METER of all band priority.
Illustrate:
Example 1, certain is surrounded by 3 METER that hit, and the dyeing situation of being calculated is respectively:
METER1: green, non-priority
METER2: yellow, non-priority
METER3: redness, non-priority
According to the method for the invention, redness is the final color of this bag, so METER1, METER2, METER3 all adopt the METER3 result calculated to carry out the renewal of token (being the deduction of token).
Example 2, certain is surrounded by 3 METER that hit, and the dyeing situation of being calculated is respectively:
METER1: green, nonpreemption
METER2: yellow, band priority
METER3: redness, nonpreemption
According to the method for the invention, yellow is the final color of this Business Stream, so METER1, METER2, METER3 all adopt the METER2 result calculated to carry out the deduction of token.
Claims (2)
1. method of supporting nested many METER system architecture is characterized in that:
1) in many METER system, behind the bag of coming in, each METER concurrent working simultaneously of hitting independently calculates dyeing situation separately, token deduction situation;
2) hit the dyeing situation that METER calculates according to each, make arbitration according to following rule, determine the dyeing situation that this bag is final, rule is: saturate METER has precedence over light-colored METER, and the degree of depth is defined as: redness＞yellow＞green; The METER of band priority has precedence over the METER that is not with priority;
3) above-mentioned each hit METER all according to the arbitration the result carry out the token deduction operation.
2. according to the described method of claim 1, it is characterized in that: said step 2) also comprise the step of judging the METER that hits before the arbitration.
