摘要

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.
