Abstract

The present invention provides an NFV resource allocation method. The method includes: modeling an NFV network, constructing a network model, modeling traffic in the NFV network, and constructing a traffic model; Model the processing and transmission processes of the data packets in the flow, and model the delays of the data packets in the processing and transmission processes according to the modeling results of the processing and transmission processes; The constraints and utility functions solve the modeling result of the delay, and obtain the resource allocation result of the traffic, so as to minimize the delay. Based on the queuing theory, the present invention models the delay in the processing process and the transmission process to evaluate the end-to-end delay when the data packet traverses the embedded NFV chain, and defines the delay-related utility function as the environmental feedback of the allocation strategy, thereby Obtain the resource allocation result with the smallest delay.

Description

technical field [0001] The invention belongs to the technical field of network function virtualization, and in particular relates to an NFV resource allocation method. Background technique [0002] With the development brought about by resource virtualization, Network Functions Virtualization (NFV) has played a central role in the development of network infrastructure. NFV supports the separation of Network Functions (NFs) from proprietary hardware devices and the flexible configuration of Virtual Network Functions (VNFs) on top of an optimally shared physical infrastructure. A group of VNFs are virtually linked together to form a Service Function Chaining (SFC). By scaling VNFs in SFC, NFV supports a more flexible approach to resource allocation between services. [0003] Due to the rapid growth of latency-sensitive services, such as audio, video, and gaming services, networks need to guarantee good latency performance to ensure reliable network services. Resource alloca...
