Abstract

The invention discloses a virtual network topological self-service generation method and system. After detecting log-in of a user terminal, a network controller detects the presence of virtual network topological resources of related users and sends the detection result to the user terminal. If the detection result indicates that virtual network topological resources of related users do not exist in the network controller, a user terminal can further determine whether the related users have the right for self-service application of virtual network topology. If related users have the right for self-service application of virtual network topology, the user terminal applies virtual network topological resources from the network controller, and generates virtual network topology according to virtual network topological resources allocating result fed back by the network controller. Virtual network topology is provided to each user through network virtualization capability of transmission SDN network, so that a user can adjust virtual network topology according to self needs.

Description

technical field [0001] The invention relates to the field of communications, in particular to a method and system for self-help generation of virtual network topology. Background technique [0002] SDN (Software Defined Network, software defined network) is one of the hotspot technologies in the field of communication and IT (Information Technology, information technology) at present. SDN is a new type of network architecture. Its core idea is to separate the control plane and data forwarding plane of the network, so as to realize programmable software control of network resources. The SDN architecture is applicable to different types of networks, including Ethernet, IP (Internet Protocol, Internet Protocol) network, and OTN (Optical Transport Network, Optical Transport Network) and the like. After applying the SDN concept to the transport network, it can improve the end-to-end networking capability of the transport network in a multi-vendor and multi-domain environment, im...
