Embodiment Construction

[0033] Below in conjunction with accompanying drawing, the present invention will be further described.

[0034] Such as Figure 1-3 As shown, the virtual network mapping method based on network topology pre-optimization and availability improvement includes the following steps:

[0035] Step (1) setting the failure rate threshold by considering the key factors of the highly available virtual network;

[0036] Step (2) Compare the set failure rate threshold with the failure rate values ​​of the underlying network nodes and links, if the failure rate value of the underlying network node is greater than the set failure rate threshold, then the node and its connected The link is removed from the underlying network topology; if the failure rate value of the underlying network link is greater than the set failure rate threshold, the link is removed from the underlying network topology; otherwise, no changes are made;

[0037] Step (3) In the node mapping stage, first sort the vir...

Abstract

The invention discloses a network topology pre-optimization-based virtual network mapping method capable of improving availability. The invention comprises the steps as follows: (1) setting a failure rate threshold value by considering a key factor of a high available virtual network; (2) comparing the set failure rate threshold value with failure rate values of a bottom network node and a link; (3) ordering virtual network requests in a unit time window according to earnings thereof in a node mapping period; (4) selecting the virtual network request whose earning is the largest, and ordering the virtual nodes in the request according to the size of the applied CPU; mapping all virtual nodes; (5) judging whether there are requests left, skipping to the step (4) if there are requests left; skipping to the step (6) if there is no request left; (6) performing link mapping to the virtual network requests whose node mappings are successfully executed by using self link mapping algorithm. The network topology pre-optimization-based virtual network mapping method capable of improving availability of the invention could effectively prevent failure in the mapping process, thereby improving high availability of the network.

Description

technical field [0001] The invention belongs to the technical field of computer communication, in particular to a virtual network mapping method based on network topology pre-optimization and usability improvement. Background technique [0002] The emergence of the Internet can be regarded as a milestone in the history of human civilization. It has profoundly affected and changed people's study, work and life style. However, with the large-scale growth of Internet users and the continuous innovation of network applications, the Internet architecture is facing new challenges and requirements. Although the traditional Internet architecture has made great contributions to the development of the Internet, its problems in terms of usability, reliability, scalability, and service quality have gradually become prominent, and it can no longer meet the support for new services. Therefore, research And deploying entirely new network technologies and structures is on the agenda. Alth...
