Electric power Internet of Things cross-domain service function chain arrangement method based on block chain

Abstract

The invention discloses an electric power Internet of Things cross-domain service function chain arrangement method based on a block chain. The method comprises six steps: S1, constructing an electric power Internet of Things cross-domain service function chain arrangement model; S2, sending a resource allocation request of the service function chain to an inter-domain controller; S3, obtaining bottom layer resource information by the inter-domain controller; S4, the inter-domain controller carrying out service function chain arrangement and resource allocation according to the underlying resource information obtained in the step S3; S5, the inter-domain controller issuing a node resource allocation strategy and a link resource allocation strategy to all intra-domain controllers; S6, the blockchain node updating the credit of the node. According to the scheme, the problems that in the prior art, part of malicious nodes have negative effects on resource arrangement of the service function chain, the trust degree is low in resource allocation in a cross-domain environment, and the resource allocation efficiency is low are effectively solved.

Description

technical field [0001] The invention relates to the resource management field of the electric power Internet of things, in particular to a block chain-based cross-domain service function chain arrangement method of the electric power Internet of things. Background technique [0002] With the rapid development and application of power Internet of Things technology, the demand for power Internet of Things in power business is increasing rapidly. In order to meet the needs of power business, network virtualization technology has become a key technology uniformly adopted by power companies and equipment manufacturers. Under the network virtualization environment, the traditional physical network is divided into the underlying network and the virtual network. The underlying network is responsible for building the underlying nodes and underlying links to provide services for the virtual network. The virtual network is responsible for renting resources from the underlying network to...
