Integrated management system for mobility of identification network and method thereof

Abstract

The invention discloses an integrated management system for the mobility of an identification network. The system comprises a plurality of identification mapping servers, each identification mapping server is responsible for managing a plurality of subnetworks, all identification mapping servers form a distributed hash table-based Overlay network, and the identification mapping servers realize the function of local gateway agency in a physical network. By copying the identification mapping relationship of a plurality of mobile nodes in proportion in the Overlay network, the influence of the mobility management caused by the inconsistent topology between the physical network and the Overlay network is reduced, the query time delay is reduced, and a query load is balanced; and due to a hierarchic registering mechanism, the updating frequentness of the mapping in the Overlay network is reduced, and the performance for updating and querying the mapping relationships is balanced.

Description

technical field [0001] The invention relates to the technical field of computer networks, in particular to an integrated identification network mobility management system and method. Background technique [0002] With the continuous advancement of technology and the continuous expansion of market scale, information networks are developing in the direction of technology integration and large-scale deployment. The converged network will be an integrated unified network, which will involve the global interconnection and interoperability of various networks, presenting a complex application environment with ever-expanding network scale, increasing number of users, and many faults. [0003] As the network environment changes, the requirements, meaning, objectives and key mechanisms of mobility management will have new features. An efficient mobility support mechanism is required to provide access and expansion capabilities for large-scale mobile networks. Efficiency here does n...

AI Technical Summary

Problems solved by technology

However, although the DHT-based overlay (Overlay) network itself has efficient routing, there is topology inconsistency between the physical network and the Overlay network, so the actual physical network performance (such as: mapping update delay, mapping query delay) may not be efficient

Moreover, the larger the network scale, the greater the degree of topology inconsistency, and the worse the network performance, which in turn affects the scalability of the network scale.
