Description
Technical field
The present invention relates to communication technique field, refer in particular to a kind of metering method and metering device of Service Source.
Background technology
In mechanics of communication, the metering method of Service Source has determined resource overall utilization rate and provides service quality etc. for user.
Taking the metering method under cloud computing environment as example, at present mostly use for reference management through quantification thinking and the model in BOSS territory for the metering of computational resource, Internet resources and storage resources, as shown in Figure 1, the main monitoring resource statistic unit by resource pool is added up the service condition of resource, and reports the management through quantification unit of cloud operation platform by interface.In service catalogue, record the service inventory that user can access, the running status of monitoring resource statistic unit charge of overseeing node, and completing user uses the statistics of node situation.Can trace back to the concrete resource using of user according to user's order, according to resource pool, resource service condition be carried out to data acquisition, can be aggregated into management through quantification unit and carry out gathering of resource service condition and analyze.
Resource metering is conventionally divided into timing metering and measures two kinds of modes by use amount.
Timing metering refers to that user is the service condition tolerance of the resource service of its time per unit, and irrelevant with its consumption, this metering method realizes simple, user is easy to accept, but impair the fairness between user, can not combine with the service condition of resource reality, be also not suitable for many COS.
By the metering of use amount, user's expense is completely relevant to the actual service condition of resource, is relatively applicable to the situation of the many resource platforms of cloud computing.There are at present following several metered scheme relevant to use amount for Internet resources:
Intelligence market metering method, main thought is in the time of network congestion, to rely on auction mechanism to determine the processing of dividing into groups.User must show to be willing to mean the ultimate cost (bid amounts bid) that each grouping pays before using network.In the time of network congestion, network can calculate a threshold value according to current network volumeter, and the grouping of only having bid amounts to be greater than this threshold value just can be transmitted, and the each grouping being transmitted can be carried out quantitative statistics according to this threshold value.
Response type metering method, according to the dynamic re-set price of the congestion condition of network, adopts closed-loop fashion to notify user, utilizes network to approach the rising of price when congested, makes user reduce traffic carrying capacity, to relax network congestion.
Priority metering method, for supporting the IP network of priority queueing.Router is put into packet in the queue of different priorities and queues up.According to priority forward, time delay or abandon.User must specify its priority needing also for the flow of different priorities pays different expenses when signing.
Equivalent bandwidth metering method, give user the responsibility of statement traffic flow parameters, require user to use exactly one group of simple numeral (as token bucket parameters) to describe Business Stream feature as far as possible, then according to the approximation of these parameter estimation equivalent bandwidths, using this as resource reservation with the foundation of metering.
Edge metering method, transfers to network edge the calculating of customer charge, instead of calculates in mode piecemeal along whole path.It seems from user, in the contract that metering is tactful, price plan is all user and the NP of access point place, specify; In the time that service relates to multiple NP, dividing of the cost between the multiple NP along forwarding on the warp of road and income is completely transparent for user.
Existing by simple timing metered scheme, do not consider the user's competition in the actual service condition of resource, make resource instream factor low; Scheme based on use amount lays particular emphasis on the metering to single network resource more, lacks support to many services type, and does not consider the cost expense that reserved resource that actual user applies for causes resource provider.
Due to the service-enriched providing under cloud platform, resource kind complexity, stoichiometric point is not often single; And in the time of a large number of users Concurrency Access, system resource will inevitably become a kind of scarce resource, occurs the competition between user, if do not adopt rational scheduling strategy, can cause the decline of all service quality, even service termination.Solve scarcity of resources problem infeasible by system own resources scheduling strategy, because can cause the unjustness between user.Supply with to ensure that by excess user's service quality is also infeasible, can cause like this significant wastage of resource, do not meet the demand for development that cloud computing resources is adjusted flexibly.Therefore need to adopt one group of metering method based on service classification, float by dosage rate, excitation user selects rational COS according to the application requirements of oneself, thereby makes system that better Differentiated Services is provided, and improves cloud computing platform entirety resource utilization.
