精品 综合业务数字宽带网（BISDN）设计 摘要 综合业务数字宽带网（BISDN）是一项充满活力、对高速发展的信息产业有极强适应能力的技术。随着数字化浪潮步伐的加快、万维网的发展、多媒体应用的普及，BISDN必将得到更广泛的应用。在现代的通讯网络建设中应有超前意识，尽快掌握好这项技术，并利用它拓展网络的功能，创造出更美好的网络环境。目前MPLS正引起广泛关注,被认为是未来三网融合的关键术之一,可以使IP网从“无连接”向“有连接”过渡,实现“电信”的下一代互联网。国内外设备厂商正在加紧MPLS产品的研究。可以乐观地相信MPLS家族是实现通信宽带化、智能化的利器,是统一各种技术和服务发展方向,是NGN(下一代网络)的核心。因特网的巨大成功TCP/IP技术功不可没,但在当前迅速发展的情况下也有不适应之处,ATM技术以其高速和灵活的服务质量控制被B-ISDN选用。IP与ATM技术的结合符合双方的生存需要。传输系统是通信网的重要组成部分，传输系统的好坏直接制约着通信网的发展。 关键字 B-ISDN TCP/IP协议 SDH 异步传输模式 MPLS 千兆以太网 Broadband Integrated Services Digital Network（BISDN）Design Zhang yi Academy of Information, Huaibei Coalindustry Teachers College, 235000 Abstract :Broad band integrated services digital network (BISDN) is a dynamic, high-speed development of the information industry is highly adaptable technologies. With the acceleration of the digital wave, Web development, multimedia application, BISDN will be more widely applied. In a modern communications network should be quick awareness building, as soon as mastering this technology and use it to expand network functions, and created a better network environment. Currently MPLS is causing widespread concern, the future integrate the three networks is considered to be one of the key techniques that can enable IP network from the no link to connect transition to telecommunications next generation Internet. Domestic and foreign equipment manufacturers are stepping up the MPLS products. MPLS can be optimistic that the family is a broadband communications technology, intelligent solution is for the uniform development of technologies and services, NGN (next generation network) core. Internet technology made TCP/IP huge success, but in the current circumstances of rapid development are not common. ATM technology, with its rapid and flexible service quality control was B-ISDN choice. IP and ATM technologies with the survival needs of both sides. Transmission system is an important component of the communications network, the transmission system
