一體化網路中身份與位置映射關係的解析方法研究

Abstract

一體化網路採用了身份與位置分離映射的機制，為使相關網路節點能夠快速準確地獲取映射資訊，需要在網路中引入一個映射關聯資料庫，以便提供全網統一的映射資訊存儲及解析服務。本文針對映射關聯資料庫在查找效率、可擴展性以及容錯性等方面的需求，提出了基於DNS(Domain Name System)遞迴分級查找、基於結構化DHT(Distributed Hash Table)網路查找和基於BGP(Border Gateway Protocol)集中式查找三種從身份資訊解析歸屬映射伺服器的方案，並進一步分析了三種方案的優缺點。本文的研究工作對於映射關聯資料庫查詢機制的設計以及部署方案的實現具有重要參考價值。Under the mechanism of separating and mapping of identity and location in the universal network, mapping information should be received fast and accurately by related network nodes. Therefore, a database providing storage and resolution services of the unified mapping information needs to be introduced into the network. To meet the demands of the mapping relationship database, such as search efficiency, scalability and fault-tolerance, this paper presents three solutions for storing and resolving the mapping information of identifier and corresponding home identifier mapping server. The schemes based on DNS (Domain Name System), DHT (Distributed Hash Table) and BGP (Border Gateway Protocol), respectively. Furthermore, the paper gives characteristic analysis for each solution. This research work is valuable for the design and implementation of the inquiry mechanism of the mapping relationship database.
