Example Embodiment

[0040] In order to make the objectives, technical solutions and advantages of the present invention clearer, the embodiments of the present invention will be further described in detail below with reference to the accompanying drawings. Other embodiments can be obtained by those of ordinary skill in the art without creative efforts.

[0041] figure 1 A schematic diagram of a network scenario provided by an embodiment of the present invention. exist figure 1 In the scenario shown, the controller is communicatively connected to the physical nodes in the physical network. The physical node may be a physical forwarding device. The physical forwarding device may be a physical switch or a physical router. Multiple physical links are formed between the physical nodes in the physical network. The controller may be a software defined network (Software Defined Network, SDN) controller. The software defined network SDN controller can use different programming languages, such as Jav...

Abstract

The invention provides a method and a controller for receiving a request. In the method for receiving the request, the controller receives the request containing the topology information of a virtual network. The controller, based on the request, determines a first physical link and a second physical link corresponding to a first virtual link and a second virtual link respectively wherein there does not exist the same physical node between the first physical link and the second physical link. With the schemes proposed by the invention, the reliability design of a user in the virtual network can be supported by a physical network, which facilitates to increase the communication business reliability. As the controller is based on the main link and the backup link of a virtual network to determine the main link and the backup link of the physical network, the reliability requirement for the communication business can be better satisfied.

Description

technical field [0001] The invention relates to the field of communication technology, in particular to a method and controller for receiving requests. Background technique [0002] With the continuous expansion of the network scale, the requirements for the network in different scenarios are more diverse. If a network is established for each scenario to meet business requirements, it will be costly and inefficient. Using network virtualization technology, multiple logically independent virtual networks are abstracted on the underlying physical network. Each business corresponds to a virtual network, and dedicated independent resources are allocated, which can solve the problem of diverse business needs. From a business point of view, the resources allocated to it are exclusive, and are isolated and unaware of each other from other businesses. From the perspective of the underlying physical network, these services share the same physical infrastructure. [0003] In a vir...
