一個基於顯示群播之改良式任意播及任意多播服務

Abstract

因為網路的日新月異，取得服務的使用者越來越多，要如何在搜尋分散服務主機中減少整體網路流量並且縮短目的主機回應時間是一重要議題。選播是在IPv6中提出的一種新型網路服務，像單播和多播一樣是網路通信服務。一個選播封包會在一群擁有相同選播位址的節點去傳遞封包到一個適合的節點。 在本篇論文中，我們一開始介紹IPv6下的選播服務。再者我們會提出幾個問題與提供解決方式，我們提出的架構有下列特色:(1)實作選播和多播通信服務。(2)減少執行選播和多播服務的整體流量。(3)比較快找到目標主機或服務。(4) 較精確地找到目標主機或服務。我們會去比對一般傳統方式和討論可適當減少的系統負擔。我們提出新的選播和多播搭配明確群播技術運作在點對點網路上。

The population of the Internet has been expanded quickly every year, so does the diversification of Internet services for subscribers. How to search the service host and reduce the network traffic load as well as shorten the response time is an important issue. Anycast is a new IPv6 feature that supports service–oriented address assignments in IPv6 networks, like unicast and multicast IP services. An anycast packet is transmitted to one appropriate node selected out of all the nodes assigned to the same anycast address. In this thesis, we first review IPv6-based anycast communications, then raise several issues and provide possible solutions to these problems. Our proposed architecture features the following characteristics: It (1) implemented anycast and manycast communications, (2) improved overall network traffic on anycast and manycast protocol, (3) reduced host response time, (4) precisely found host or service. We also investigate and compare the traditional methods and discuss the appropriate techniques for reducing overheads as much as possible. Consequently, we propose new anycast and manycast based on Xcast mechanism, we then applies the proposed method to p2p network IPTV and evaluate their performance improvement.
