Resource provision method for service composition problem in cloud-integrated wireless-fiber hybrid access network

Abstract

The invention discloses a resource provision method for the problem of service composition in a cloud-integrated wireless-fiber hybrid access network, which includes three stages. The first stage: Decompose the comprehensive service request into a variety of basic services, collect the user's comprehensive service request, the price issued by each service facility, the total amount of resources, and the basic consumption of basic services per unit, and aim at the minimum cost for users according to the market mechanism Construct an auction model; the second stage: design an algorithm based on the auction model, find out the resource provision plan and the corresponding unit basic service pricing strategy that achieves the minimum user cost; the third stage: verify that the designed algorithm has incentive compatibility and time complexity low-level features. The present invention plans the interaction between service facilities and users into an auction model, enabling users to obtain services at a minimum cost, and at the same time allowing service facilities to actively participate in cloud services after receiving certain rewards, thereby providing users with various cloud services more efficiently.

Description

technical field [0001] The invention belongs to the field of wireless-optical hybrid access networks, and in particular relates to a resource provision method for service combination problems in cloud-integrated wireless-optical hybrid access networks. Background technique [0002] The access network, commonly known as the "last mile" network, is an important infrastructure for end users to obtain network services. Today's access network is mainly divided into two categories: wired access network and wireless access network. Optical fiber access network has become a very attractive wired access method because it can provide stable and high-speed access bandwidth. However, the in-depth laying of optical fiber is relatively expensive and lacks flexibility. Wireless access networks can provide ubiquitous network access services and their deployment costs are relatively low. However, problems such as network transmission interference, limited transmission range, and low network...

[0007] In fact, blindly pursuing the minimization of user costs without certain incentives may cause service facilities to be unwilling to provide users with resources to complete service requests because they fail to obtain satisfactory benefits
