三网融合是网络发展的主要方向,无线网络是接入有线网络的一个重要途径。本文主要概述了因特网、电信网络、有线电视网络和无线网络的技术现状;分析在三网融合的形势下,它们各自都可以为发展未来包含现在由三种网络提供的所有服务的综合业务网提供核心技术的能力;指出没有单个网络技术能够成为无争议的赢家:融合的网络将具有异构网络集合的特征,提供多种多样的服务;然后在更广阔的视野上阐明了在三网融合之后的未来全局多媒体网络的特征以及建立具有这样的特征的网络所面临的挑战和所需要的变革和创新。
Triple play is the main direction of network development, wireless network is an important way to access the wired network. This article provides an overview of the state of the art on the Internet, telecom networks, cable networks and wireless networks. Analyzes In the triple-play scenario, each of them can provide for the future development of an integrated services network that will include all the services currently offered by the three networks Core technology; pointed out that no single network technology can become the undisputed winner: converged network will have the characteristics of heterogeneous network aggregation, providing a wide range of services; and then clarified in a broader perspective after the triple play The characteristics of the future global multimedia network and the challenges and the required changes and innovations in establishing networks with such characteristics.
