Problems solved by technology

The quantification of the two factors is too simple and rigid, which is not conducive to the dynamic adjustment of migration timing
Moreover, the various factors that determine the migration are interactive, and the simple comparison of the size cannot reflect the relationship between the various factors.
Although MIX k The roaming cost due to cross-domain is added to the algorithm, but there are still problems with the above-mentioned quantification and simple relationship description

Embodiment Construction

[0063] The technical solutions of the present invention will be described in further detail below with reference to the accompanying drawings and embodiments.

[0064] Figure 5 It is a flowchart of a virtual service migration method in an embodiment of the present invention.

[0065] like Figure 5 As shown, first in step 501, migration evaluation parameters are selected according to service types and user needs. The monitor monitors the virtual nodes in the network, and when a new request arrives or a user request changes, the status information about the evaluation parameters of the virtual node is obtained.

[0066] Specifically, the cost of a virtual node / virtual server is jointly affected by multiple factors. In order to simplify the problem, an embodiment of the present invention only considers the situation that there is only one virtual network on the physical network, and the situation that there is only one virtual node / server in the virtual network.

Abstract

The invention relates to a virtual service migration method, comprising: selecting migration evaluation parameters according to service types and user needs, a monitor monitors virtual nodes in the network, and when a new request arrives or a user request changes, the evaluation parameters of the virtual node are obtained State information of parameters; calculate the service migration cost of each virtual node according to the state information; obtain the virtual node with the smallest virtual service migration cost from the virtual nodes as a service node through the migration cost calculation method; select the service node pair The virtual service is migrated. The virtual service migration method provided by the present invention can effectively synthesize the influence of various factors on the migration, judge and execute the migration, realize network resource management and improve user service experience quality by using the service migration.

Description

technical field [0001] The invention relates to the field of mobile Internet, in particular to a virtual service migration method. Background technique [0002] With the increasing development of science and technology, the mobile Internet has become one of the main trends in the development of the Internet. According to statistics, as of March 2013, the number of fixed Internet broadband users in my country was 181 million, while the number of mobile Internet users had reached 817 million. With the increasing demand for network mobility, changes in user behavior, continuous enrichment of information interaction types, and increasing data traffic, ensuring and improving user service experience quality has become a new challenge for the Internet field. The development of virtualization technology provides the possibility to solve the problem of mobility. The goal of virtualization is to realize the smooth movement of virtual services without considering the properties of th...
