數位匯流時代的來臨，各項服務應運而生，且和網路的演進息息相關；服務多樣化、網路傳送IP化，是目前網路發展的趨勢。而這些服務皆是以IP（Internet protocal）技術為基礎的網際網路服務。這些服務可分為三大類，第一為互聯網的接入服務，第二為IP電話（VoIP）的服務，第三為專用服務，如內容分配、VPN、虛擬專用網和IPTV等。當這些網際網路的服務蓬勃發展時，建立一個多樣式存取的IP網路絕對是一個必然的趨勢。但現今使用之網際網路通信協定32位元的IPV4網路定址方式正加速面臨位址即將耗盡的問題。而未來網路應用服務，如網路安全、保障頻寬以及使用者付費下的分級服務（Differentiated Services）等，消費者對於網路服務品質（QoS）的要求不斷的提高，而傳統的IPV4所訂定的相關協定已無法滿足未來網際網路的需求。所以產業界能否找出一套徹底解決網際網路IP位址不足的方法，並有效的因應未來網際網路多樣性服務的發展需求，不僅是產業界未來的商機所在，更影響致國家經濟的整體發展。
鑑於IP-Based是網路通訊應用服務的重要基礎，而現有的IPV4又無法提供足夠的位址空間給這些遽增的使用者，因此國際網際標準組織IETF訂定了新一代網際網路通信協定IPV6。IPV6提供了128位元的位址空間，足以應付未來ALL-IP網路的需求。IPV6不但解決IPV4位址空間不足外，也同時解決在IPV4所產生的問題與缺陷，如安全性、移動性及服務品質。IPV6可協助業者開發各種新型態的服務，例如數位家庭、多媒體通訊、智慧電網、視訊監控等不同創新型態的應用服務領域。同時也加入自動配置（Auto-Configuration）的特性，且對於網路通訊安全性、保密性、網路品質QoS等都有嚴格的要求，可說是數位匯流時代中，最重要的核心基礎。本文章以網路效能探討現有IPv4的IPTV架構，引進IPv6技術的可行性研究。

The era of digital convergence, the service came into being, and the evolution of closely related and network; diversification of services, delivery of IP-based network, is the trend of network development. These services are based on IP (Internet protocal) technology-based Internet service. These services can be divided into three categories, first for the Internet access service, the second for IP telephony (VoIP) services, and the third for the special services such as content distribution, VPN, virtual private networks, and IPTV. When these services have become the Internet's development, the establishment of a multi-style access to the IP network is definitely an inevitable trend. However, the current Internet protocol used 32-bit addressing mode is accelerating IPV4 network address facing the problem of running out. The future network applications such as network security, bandwidth, and user fees under the protection of the grading services (Differentiated Services), etc., the quality of consumer Internet service (QoS) requirements continue to increase, while the traditional IPV4 relevant agreements stipulated in the Internet has been unable to meet future demand. So the industry can find a complete internet solution to the lack of IP addresses, and effective response to future Internet development needs of the diversity of services, not only is the industry's future opportunities lie, but also affect the national economy caused by the overall development.
In view of IP-Based network communication applications is an important foundation, and the existing IPV4 and can not provide enough address space to the dramatic increase in users, the international Internet standards body IETF to set the next generation Internet protocol IPV6. IPV6 provides 128-bit address space, enough to meet the future needs of ALL-IP network. IPV6 IPV4 address space will not only solve, but also to solve the problems arising in the IPV4 and defects, such as security, mobility and quality of service. IPV6 can help the industry develop new types of services such as digital home, multimedia communications, smart grid, video surveillance and other innovative types of applications in different fields. Also added auto-configuration (Auto-Configuration) feature, and Internet communications for security, privacy, network quality, there are stringent QoS requirements, can be said that the era of digital convergence, the most important core foundation.
