Abstract

The invention discloses a virtual network topology self-help generation method and system. Wherein, after detecting that the user terminal logs in, the network controller detects whether there is currently a virtual network topology resource of the relevant user, and the network controller sends the detection result to the user terminal. If the detection result indicates that there is no virtual network topology resource of the relevant user in the network controller, the user terminal further determines whether the relevant user has the right to apply for a virtual network topology by itself. If the relevant user has the right to self-apply for virtual network topology, the user terminal applies for virtual network topology resources from the network controller, and the user terminal generates a virtual network topology according to the virtual network topology resource allocation result fed back by the network controller. The present invention provides each user with a virtual network topology by using the network virtualization capability of the transmission SDN network, so that the user can adjust the virtual network topology according to his own needs.

Description

technical field [0001] The invention relates to the communication field, 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 hot 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 of the network from the data forwarding plane, 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), etc. 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, improve the s...
