现今所谓的“宽带城域网”(BMAN),是在Internet广泛发展和应用之后,信息化浪潮高涨的背景下提出的新概念。中科院计算技术研究所首席科学家王行刚老师对宽带城域网的特点、技术与发展策略进行了解答。问:宽带城域网特点是怎样的? 1.多业务的综合信息网 BMAN不仅提供“市话网”的话音业务,或者仅提供“有线电视网”的视频业务,也不仅停留在第一代互联网的数据业务,而应当提供话音、视频、数据和多媒体业务,成为一种新型的多业务网。它作为一种公用网,应当具有电信网的可靠性和可管理性.采用公众和网络运营商都能接受的运营模式,而区别于现今
Today’s so-called “broadband MAN” (BMAN) is a new concept proposed in the context of the wave of informationization after the widespread development and application of the Internet. Wang Xingang, chief scientist of CAS Institute of Computing Technology, answered questions about the features, technologies and development strategies of broadband metropolitan area networks. Q: What is the characteristic of broadband metropolitan area network? 1. Multi-service integrated information network BMAN not only provides “local network ” voice service, or only provide “cable network ” video services, not only stay in The first generation of Internet data services, but should provide voice, video, data and multimedia services to become a new type of multi-service network.
