【摘要】：由于多宿主、流量工程等技術(shù)的廣泛應用,越來越多的不可聚合的地址碎片被注入到核心網(wǎng)中,導致嚴重的路由可擴展性問題。該問題對核心網(wǎng)路由器的影響主要體現(xiàn)在兩方面:要保存的路由表不斷增大和要處理的路由更新不斷增多。為了解決這個問題,許多可擴展路由方案被提出,主要包括基于主機的ID/Loctor分離、邊緣/核心網(wǎng)絡(luò)地址分離、路由聚合、緊湊路由、地理信息路由等。對現(xiàn)存的可擴展研究方案進行全面的調(diào)研和分析,主要包含路由可擴展問題原因分析、可擴展路由方案分類、可擴展路由介紹和總結(jié)比較。
[Abstract]:Due to the wide application of multi-host, traffic engineering and other technologies, more and more non-aggregate address fragments are injected into the core network, resulting in a serious routing scalability problem. The influence of this problem on core network routers is mainly reflected in two aspects: the increasing number of routing tables to be preserved and the increasing number of routing updates to be processed. To solve this problem, many extensible routing schemes have been proposed, including host-based ID/Loctor separation, edge / core network address separation, routing aggregation, compact routing, geographic information routing, etc. This paper makes a comprehensive investigation and analysis on the extant extensible research schemes, mainly including the cause analysis of routing extensibility problem, the classification of extensible routing schemes, the introduction and summary of extensible routes.
