Embodiment Construction

[0087] In order to make the above objects, features and advantages of the embodiments of the present invention more comprehensible, the embodiments of the present invention will be further described in detail below in conjunction with the accompanying drawings and specific implementation methods.

[0088] Software defined network (SDN for short) is a new type of network architecture, which provides easy Deploy and scale web services.

[0089] see figure 1 , the system for deploying an SDN service provided by the embodiment of the present invention includes an SDN controller and an upper-layer application. The SDN controller receives a service request from an upper-layer application, and the service request includes service parameters and service types, such as VPN, tunnel, etc.; and deploys services corresponding to the service type according to the service request.

[0090] Such as figure 1 As shown, the system further includes a PE device; optionally, a PCE and a policy m...

Abstract

Disclosed are a method for deploying a service by an SDN and an SDN controller. The SDN controller receives a service request from an upper-layer application, the service request comprising a service type and service parameters, and the service type being a tunnel or a VPN service; and the SDN controller obtains path information of the tunnel or information of at least one PE device corresponding to the VPN service, and notifies the obtained information to an ingress network node of the tunnel or the at least one PE device, so as to complete deployment of the tunnel or the VPN service. The problems in the prior art that the deployment of the VPN service by manual configuration requires a lot of time, is error prone, complex in tunnel establishment, and poor in service expansion can be solved.

Description

technical field [0001] The present invention relates to the field of network communication, and in particular to a method for deploying services in a Software Defined Network (SDN for short) and an SDN controller. Background technique [0002] A virtual private network (Virtual Private Network, VPN for short) service is an important service provided by network operators to customers. Currently, the main way to establish a VPN in a network is to manually configure a provider edge (PE for short) device according to user requirements, and establish a VPN connection between PEs. [0003] Network operators usually use tunnels to provide VPN services to users. A commonly used tunnel is a Traffic Engineering (Traffic Engineering, TE for short) tunnel; the advantage of a TE tunnel is that an operator can control a tunnel path and implement bandwidth guarantee. Currently, TE tunnels are established in the network mainly through manual configuration on the router, and the head node ...
