支援接入與核心分離的路由協定擴展機制設計與實現

Abstract

為解決現有互聯網的可擴展性問題，目前有許多研究方案提出將現有互聯網劃分為接入網路和核心網路兩個獨立的演進空間。在分離後的新網路環境當中，現有路由協定需要加入特定處理機制以提供準確的路由可達性資訊。本文在深入研究現有路由協議基礎上，設計和實現在核心與接入網路空間分離下對現有路由協定的擴展機制。To resolve the scalability problem in the existing Internet, there are many researches proposing the idea of separating the Internet into two independent evolving spaces, called the access and core network, respectively. In the new network environment, the existing routing protocols require additional mechanisms to provide accurate reachability information. In this paper, based on the in-depth study of the existing routing protocols, we design and implement the extensions to the existing routing protocols to support the separation of the two spaces.
