Embodiment Construction

[0065] The specific steps of a revenue-based request access control method in a distributed multi-cloud data center will be given below.

[0066] The first step is to establish a queuing system model for distributed multi-cloud data centers

[0067] Assuming that the arrival of requests for each application n in the cloud data center conforms to the Poisson distribution, the corresponding request arrival rate is Model the distributed multi-cloud data center as an M / M / m queuing system. For application n, the average processing capability of each corresponding physical server is defined as the average processing capability of all physical servers corresponding to the application in the distributed multi-cloud data center. In addition, it is assumed that the physical server that has been turned on is always busy, that is, there are always requests waiting to be processed in the request queue. Therefore, the estimated response time ERT for each request of application n n It ca...

Abstract

The invention relates to a profit based request access control method in a distributed multi-cloud data center. According to the profit based request access control method, requests can be accepted selectively, requests with high priorities are prone to be accepted through comprehensive consideration of factors such as the priority, profit and expected response time of each request, and the total bandwidth requirement of all the accepted requests is guaranteed to be not more than the total bandwidth of all the usable network service providers. An M / M / m queuing system model aiming at the distributed multi-cloud data center is built based on a queuing theory according to user requests as well as network and server resources. An effect function capable of transforming the response time of each application request into corresponding profit is designed based on the model. A constraint nonlinear planning model of request access control in the distributed multi-cloud data center is built. A profit based request access control strategy is provided by adopting a penalty function and a mixed heuristic optimization algorithm. According to the profit based request access control method in the distributed multi-cloud data center, requests of various applications can be accepted selectively, and the profit of the distributed multi-cloud data center providers is accordingly maximized.

Description

technical field [0001] The invention relates to a revenue-based request access control method, in particular to a revenue-based request access control method in a distributed multi-cloud data center. Background technique [0002] At present, the infrastructure resources in the cloud data center run a large number of application services at the same time, and provide services to users from all over the world. To improve application performance and availability, each cloud data center provider manages a data center network consisting of multiple cloud data centers spread across multiple locations. Similarly, for performance and cost considerations, each cloud data center is connected to multiple network service providers. These network service providers are responsible for transporting the data that interacts between a large number of users from all over the world and cloud data center providers. [0003] A user's request must first pass through a wide area network link comp...
