Abstract

The present invention proposes a calculation method for end-to-end cloud service delay, including one: the end-to-end multi-job request is converted into a multi-queue system; the request queue entering the admission control system is called the request uplink queue, and the request queue coming out of RP&DDM is called is the request downlink queue; second: the multi-queue system is modeled based on layered CTMC; layered CTMC chains are used to model end-to-end cloud services, and the state spaces of the first and second layer CTMC chains are respectively Λ and their State transition probabilities. Three: end-to-end application delay calculation; the end-to-end delay includes queue waiting delay, resource deployment delay and execution time. The present invention is suitable for multi-job type and multi-server type cloud service scenarios, and the calculation results are more in line with the actual cloud application environment; by describing its random characteristics through layered CTMC, the description of end-to-end cloud service characteristics is more complete and accurate, and it is easy for the actual system accomplish.

Description

technical field [0001] The invention relates to a calculation method for end-to-end cloud service delay, which belongs to the technical field of the Internet. Background technique [0002] Most cloud service providers use virtualization technology to share physical resources. For example, Amazon EC2 and GoGrid use Xen virtualization (document [1]) to support multiple virtual machine instances on a single physical server (document [2-3]). An important feature of the virtualization technology is that a single server is shared by multiple performance-independent platforms, ie, virtual machines (Virtual Machines, VMs), through virtualization of physical resources (such as processors and I / O interfaces). Researchers have pointed out through a large number of studies that virtualization technology has a serious impact on cloud service computing and communication performance. For example, literature [4] communicates with other Internet location servers through Amazon EC2, and meas...
