Problems solved by technology

[0004] However, due to the random selection of VNFs, the selected VNFs may be less secure, and the less secure VNFs are vulnerable to cyber attackers, resulting in less secure service function chains deployed

Embodiment Construction

[0077] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0078] see figure 1 , figure 1 It is a schematic flowchart of the first service function chain deployment method provided by the embodiment of the present invention, and the above method includes S101-S106.

[0079] S101: Determine the expected security value of the service function chain to be deployed according to the service request to be responded to.

[0080] The service requests to be responded to above are used to request services. For example, the a...

Abstract

The embodiment of the invention provides a service function chain deployment method and device, and the method comprises the steps: selecting a VNF from all preset virtual network functions (VNFs) ofeach service type requested by a service request, and obtaining a VNF set with the number of VNFs being all numbers in a preset number range; obtaining each first combination, wherein each first combination comprises a VNF set corresponding to each service type; based on the adjusted security value and deployment consumption of each second combination, selecting a second combination for deployingthe service function chain to be deployed in each second combination, the second combination being a first combination in which the security value of the first combination is greater than an expectedsecurity value; and deploying the to-be-deployed service function chain for the VNF in the selected second combination according to a preset logic sequence. When the scheme provided by the embodimentof the invention is applied to deploy the service function chain, the security of the deployed service function chain can be improved.

Description

technical field [0001] The present invention relates to the technical field of communication security, in particular to a service function chain deployment method and device. Background technique [0002] The service function chain is a set of ordered VNFs (Virtual Network Function, virtualized network function), and the VNFs are used to provide services. Since the service request may include a series of service types to be requested, when the service requests are different, the service types included in the service requests are also different, so the VNFs in the service function chain used to respond to service requests are also different. [0003] In order to meet different business requests of users, it is necessary to deploy service function chains for different business requests, so as to respond to user business requests based on the deployed service function chains. In the prior art, when deploying a service function chain, generally based on the service type of each...
