Abstract

An embodiment of the present invention discloses a gateway virtualization method. The method comprises the steps: receiving a network service request, and then requesting a software-defined network (SDN) controller to allocate resources according to the network service request. The network service request includes virtual network element requirements, and the virtual network element requirements include one or more virtual gateway forwarding requirements. Meanwhile, the embodiment of the present invention also discloses a gateway virtualization system.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a gateway virtualization method and system. Background technique [0002] Network Function Virtualization (NFV, Network Function Virtualization) technology utilizes Internet technology (Information Technology, IT) virtualization technology, uses common industrial standard high-capacity servers, switches and storage, and integrates existing network functions into the above-mentioned common hardware devices , so as to achieve the purpose of reducing hardware types, shortening the deployment cycle of new services, and reducing costs. NFV defines a common platform that supports the virtualization of various networks. The schematic diagram of the architecture of NFV in the prior art is as follows figure 1 shown. [0003] exist figure 1 Among them, the orchestrator (Orchestrator) is responsible for receiving network service requests configured from the operation supp...
