Embodiment Construction

[0034] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention. Apparently, the described embodiments are only some of the embodiments of the present invention, but not all of them. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0035] figure 1 Shown is an architecture diagram of physical network virtualization according to an embodiment of the present invention. The physical network virtualization architecture includes a virtual network layer and a physical network layer (ie, the infrastructure ne...

Abstract

The embodiment of the present invention discloses a virtual network fault recovery method, including: a network device (for example, a transmission controller) determines that a physical link in the physical network fails, and the failed physical link corresponds to the virtual At least one virtual link in the network; map at least one virtual link corresponding to the failed physical link to a non-faulty physical resource in the physical network, and the non-faulty physical resource satisfies the at least Transmission bandwidth of each virtual link in a virtual link. Through the above technical solutions, the fault recovery of the virtual network can be realized. When the physical resources corresponding to the virtual network fail, the virtual network can quickly recover from the fault, and the topology of the virtual network after the fault recovery is the same as before the fault, which improves the user experience. experience.

Description

technical field [0001] The present invention relates to the technical field of communications, in particular to a method and device for recovering from a virtual network failure. Background technique [0002] With the development of Internet technologies, especially the rapid development of data centers (Data Centre, DC), customers have an increasing demand for transmitting network traffic. Therefore, customers usually not only need to rent point-to-point connections to transmit data, but also need to rent virtual networks to connect multiple customer service access points (such as DCs). Customers can establish a connection between any two service access points according to their own needs in the leased virtual network to transmit customer data. [0003] Network virtualization, that is, on a shared physical platform, through virtualization technology, the physical node resources (computing resources, forwarding resources, etc.) This is abstracted, partitioned and combined ...
