Embodiment Construction

[0019] 1. Network topology

[0020] Use as figure 1 The three-layer hierarchical network topology shown. The first layer consists of access points or base stations, so-called mobile edge computing nodes, which directly communicate with mobile IoT devices through Wi-Fi or mobile networks. A regional management node, the regional cloud, will manage mobile edge computing in the same region. Regional clouds (in layer 2) can communicate and share information with each other. The regional cloud is managed by the core cloud, which is the central management node (layer 3) of the network operator. For simplicity, the term "node" is used below to collectively refer to mobile edge computing nodes, core clouds, and regional clouds.

[0021] 2. Mobile edge computing node architecture

[0022] figure 2 The detailed architecture of the mobile edge computing node is shown, including four main components: 1) aggregator; 2) edge computing service pool; 3) edge computing service controller; 4) ser...

Abstract

The invention discloses a decentralized mobile edge computing resource discovery and selection method and system. The method and the system are used for solving the problems of how to select servicesrequested by a mobile edge computing node to deploy Internet of Things equipment with optimal service quality by a service provider and how to discover existing services in adjacent mobile edge computing nodes so as to avoid repeated deployment and save edge resources. Through a three-layer layered mobile edge computing network topology, mobile edge computing nodes are put into a plurality of clusters / groups according to geographic positions, each cluster is controlled by regional cloud, and the computing overhead is reduced compared with the adoption of a centralized controller. Based on a content center network, through expanding a content center network table, a unified protocol is introduced, and service autonomous discovery and autonomous deployment are realized. The computing servicequality such as transmission delay and node performance is comprehensively considered through a mathematical model, and service discovery and deployment decisions are made, so that the service quality of the node where the requested service instance is located is optimal for the Internet-of-things equipment requesting the service.

Description

Technical field [0001] The present invention relates to the field of mobile edge computing in the field of computer science, in particular to the field of service discovery and deployment based on a content center network. Background technique [0002] Mobile edge computing is used to transfer services from cloud computing servers to mobile edge computing nodes in order to provide these services to mobile IoT devices near the mobile edge computing nodes. However, even if mobile edge computing has distance advantages, we still face many technical challenges, such as how service providers choose target mobile edge computing nodes so that the requested service can be deployed with the best service quality; and how to find neighboring mobile edges Existing services in computing nodes to save edge computing resources. [0003] The traditional TCP / IP system network lacks broadcasting and forwarding mechanisms, so it is difficult to construct an effective service discovery decision-makin...
