A Multi-Agent-Based Dynamic Data Source Management Method

Abstract

The invention relates to a multi-agent dynamic data source management method. When data content is generated in a network, the Provider sends a Register report containing both content names and signature information to all mobile proxy servers MAs in the network; after the MAs receive the Register report, the Provider calculates the data source request mobility PRMR value of the self-carried content; according to the PRMR value, either the binding updating mode or the caching processing mode is adopted. According to the invention, movement updating of the data source is carried out among a plurality of agents, corresponding management strategies are adopted according to different communication modes, content caching is performed reasonably, switching time delay caused by movement of the data source is reduced by making the best of the network property, the data network properties are optimally denominated, the network updating expenditure is reduced, and the mobility of the data source is supported.

Description

technical field [0001] The invention relates to the field of computer networks, in particular to a multi-agent-based dynamic data source management method. Background technique [0002] As people's dependence on IT products continues to increase, Internet mobile traffic surges, people's demand for data content is increasingly strong, and the main body of network applications is gradually evolving to content requests and information services. In order to meet the ever-increasing demand for data content access on the Internet, Information-Centric Networking (ICN), as a revolutionary (Clean-Slate) future Internet design idea, makes data content itself the main unit of network communication, and will The network communication model has changed from focusing on "where" (address, server) to focusing on "what", that is, the purpose and intention of communication between users and applications, and has become an important model for future Internet design. At present, information-ce...

Problems solved by technology

as attached figure 1 As shown, the mobile data source (Mobile Source, MS) generated by the Z domain disconnects from the Z domain and moves to the Y domain. Consumer C still goes to the Z domain to request data according to the name route, but because the MS has moved to the Y domain , the requester will not be able to obtain any data content

[0003] Researchers have proposed some solutions to the above problems. These solutions solve the routing update problem to a certain extent, but there are still many deficiencies: On the one hand, under the TCP / IP architecture, the network passes the Border Gateway Protocol , BGP) and core routers (Core Routers, CR) to update the routing table for data source mobility management is not suitable for NDN networks with a large number of mobile entities, and considering the effective use of cache, based on encapsulation and temporary modification of content identification The scheme should not be adopted
