Abstract

The invention provides an end-to-end cloud service delay calculation method. The method comprises the steps: 1, converting an end-to-end multi-job request into a multi-queue system, wherein a requestqueue entering an admission control system is called a request uplink queue, and a request queue coming out of the RP & DDF is called a request downlink queue; 2, modeling the multi-queue system based on the layered CTMC; using a layered CTMC chain for end-to-end cloud service modeling, setting the state spaces of a first layer CTMC chain and a second layer CTMC chain are [lambda] and [lambda]<k> respectively, and calculating the state transition probabilities of the first layer CTMC chain and the second layer CTMC chain separately; 3, performing end-to-end application delay calculation, wherein the end-to-end delay comprises queue waiting delay, resource deployment delay and execution time. The method is suitable for multi-operation-type and multi-server-type cloud service scenes, andthe calculation result better conforms to the actual cloud application environment; random characteristics are described through hierarchical CTMC, end-to-end cloud service characteristic descriptionis more complete and accurate, and actual system implementation is facilitated.

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...
