摘要

近年來隨著網際網路發展的日益蓬勃，使得用於網際網路上的各種應用也日益增多；而隨著使用者以及應用的增加，連帶使得網路上的各項種類的訊務量也隨之增加。有鑑於此，如何有效的利用網路頻寬似乎已成為當今改善網際網路環境日趨擁擠情形的重要課題。
本論文中，我們將會探討以及實際模擬在自治系統的環境下，以全互連（Full-Mesh）的情況做IBGP路由交換；之後我們會加入路由反射器，並且以減少mesh數目之目的下予以一至多階層化做適當的配置；然後利用數據以及圖表探討評估全互連以及路由反射器階層化配置的情況之下所帶來的改善以及影響。

After the rapid development of the Internet in recent years, more and more applications have been deployed in Internet. Due to a large number of the users and applications being introduced, various kinds of the data flows get rising accordingly. In accordance with this situation, it is an important subject to improve the performance of Internet through the effective arrangement of network bandwidth so that the traffic congestion can be avoided.
In this thesis, we focus on the discussion and reviewing of the “IBGP” routing information’s exchange of the AS’s (Autonomous System) and the interconnection of PE routers of PPVPN through the Full-Mesh’s environment at first. Base on the subject of path complexity occurred in mesh topology, we study the use and architecture of route reflectors (RR) with multi levels manner to reduce the topology. We analyze and compare the improvement and effect of the Full-Mesh RR and the proposed Multi-Level RR exhaustive simulations.
