Abstract

The embodiment of the invention discloses an SDN (Software Defined Network) service implementation method applied to an application entity. The SDN service implementation method comprises the steps of obtaining position related information of at least one virtual machine which corresponds to at least one virtual network management entity; distributing a network resource for the virtual machine corresponding to the position related information to obtain network resource related information; generating service chain related information based on the network resource related information and the position related information, wherein the service chain related information can represent the corresponding relationship between the SDN service and the at least one virtual machine; and sending the service chain related information to an SDN controller and sending the network resource related information to the at least one virtual network management entity. The embodiment of the invention also discloses the application entity, the management entity and the controller.

Description

technical field [0001] The present invention relates to a software-defined network (SDN, Software Defined Network) technology, and in particular to an SDN service implementation method, an application entity, a management entity, and a controller. Background technique [0002] Service chaining means that tenants pass several types of traffic sequentially through different network functional network elements according to their own business requirements, so as to achieve the effect of service orchestration; The traffic path for Web Server to access the application server (App Server) is [0003] The core functions of the existing service chain include: (1) flow classification; (2) sequential scheduling of specified flows; (3) network function nodes, such as firewalls (FW, FireWall), load balancers (LB, Load Balance), Corresponding policies are configured on the WAN virtual private network (VPN, Virtual Private Network) gateway, and the policies are completely isolated, eve...
