Embodiment 1

[0098] Such as figure 1 As shown in FIG. 1 , it is a schematic flowchart of a method for deploying a virtual network service provided by Embodiment 1 of the present invention. The method can be described as follows.

[0099] Step 101: Obtain NSD information corresponding to the NSD index according to the NS information model description template NSD index carried in the received network service NS instantiation request.

[0100] Wherein, the NSD information includes at least one NS deployment parameter.

[0101] Each NS deployment parameter includes at least the capacity of the NS, at least one VNF instance type, at least one VNF instance corresponding to each VNF instance type, the VNF information model description template VNFD information corresponding to each VNF instance type, and each VNF instance The scale parameter of the VNF instance corresponding to the type.

[0102] Wherein, the ratio parameter is used to represent the ratio of the capacity of the VNF instance t...

Embodiment 2

[0132] Such as figure 2 As shown, it is a schematic flowchart of a virtual network service deployment method provided by Embodiment 2 of the present invention. The method can be described as follows.

[0133] Step 201: The Orchestrator obtains NSD information corresponding to the NSD index according to the NS information model description template NSD index carried in the received network service NS instantiation request.

[0134] Wherein, the NSD information includes at least one NS deployment parameter.

[0135] Each VNF deployment parameter includes at least the capacity of NS, at least one VNF instance type, at least one VNF instance corresponding to each VNF instance type, the VNF information model description template VNFD information corresponding to each VNF instance type, and each VNF instance The scale parameter of the VNF instance corresponding to the type.

Abstract

Disclosed are a virtual network service deployment method and device. The method comprises: according to an NSD index carried in a received network service (NS) instantiation request, acquiring NSD information corresponding to the NSD index; determining a VNF instance meeting capacity requirements of an NS to be instantiated carried in the received network service (NS) instantiation request from the acquired NSD information; and according to a proportion parameter of the determined VNF instance and the capacity of the NS to be instantiated, calculating the capacity of the determined VNF instance; according to the capacity of the determined VNF instance and VNFD information corresponding to the determined VNF instance, obtaining a resource required by the determined VNF instance; and according to the determined resource, conducting virtual network service deployment on the determined VNF instance, thereby realizing the deployment of multiple VNF instances and the automatic adjustment of the capacity of the deployed VNF instances, and effectively saving virtual resources.

Description

technical field [0001] The present invention relates to the technical field of network function virtualization, in particular to a virtual network service deployment method and equipment. Background technique [0002] With the development of Internet technology, the network deployed by network operators is composed of various physical devices. Different network services require different physical devices. Every time a new network service is developed, a new type of physical device needs to be added accordingly. However, it becomes more and more difficult to determine the spatial location of the new physical device and the power supply line with the increase of network services. difficult, which seriously inhibits the deployment of new network services. [0003] In order to solve the above existing problems, Network Functions Virtualization (NFV, Network Functions Virtualization) is proposed. Network Functions Virtualization refers to running network functions on general phy...
