Embodiment Construction

[0019] The invention uses the method with the highest success rate to remap the current virtual network mapping based on the virtual network rapid healing method of the multi-commodity flow problem model, and fully considers the load balance of the physical network. Including the control protocol for the communication between the underlying network provider (InP) and the service provider (SP), the recovery (remapping) process of the invalid virtual network mapping, the response strategy for the failed virtual network mapping, and the recording of the virtual network mapping in the physical network. The method of failure times of each node link.

[0020] The purpose and effects of the present invention will become more apparent by referring to the accompanying drawings in detail of the present invention.

[0021] The present invention is based on the multi-commodity flow problem model virtual network rapid healing method, comprising the following steps:

[0022] 1. In the proc...

Abstract

The invention discloses a rapid restoring method for a virtual network based on a multi-commodity flow problem model, which comprises a communication protocol between a bottom network provider and a service provider, a restoring process for failed virtual network mapping, a coping strategy for unsuccessfully-restored virtual net mapping, and a method for recording failure times of each node link in a physical network. The rapid restoring method for the virtual network based on the multi-commodity flow problem model better adapts to the current internet environment, has effective and rapid running process, and has very high recovery success rate; moreover, the running result of the rapid restoring method for the virtual network based on the multi-commodity flow problem model better improves the loading balance of the network.

Description

technical field [0001] The invention relates to a recovery method using the solution of the multi-commodity flow problem after the virtual network mapping fails, in particular to a virtual network fast healing method based on the multi-commodity flow problem model. Background technique [0002] The Internet has achieved great success in the past few decades, and it provides people with a brand-new platform for exchanging information and receiving information. Its widespread popularity has promoted the development and application of network technology. However, the huge network also limits its future development. For example, with the scale and size of the current network, it is undoubtedly very difficult to deploy new network technologies. Network virtualization technology provides a powerful solution to allow multi-architecture of the network. Network virtualization refers to connecting virtual routers through virtual links, and using different protocols to provide users...
