宽带网关键技术发展走向

The Development Trends of Broadband Network Key Technologies

摘要:随着Internet的飞速发展,在网络的几乎所有层面(如企业网、接入网、选路与交换、传送)都在开发与应用高速技术,宽带网步入了快速发展的阶段。与此同时,宽带多媒体应用的发展促进了宽带接入的发展,宽带接入已经开始走向大众化,企业(甚至家庭)采用以太网接入也在逐渐普及,这些将为已经建设的宽带骨干网带来巨大的业务量。这里将从新的宽带网模型着眼,探讨核心交换路由器、光传送网、多协议标记交换(MPLS)与QoS的发展走向。

With the rapid development of Interent,high-speed technoligies are developed and applied in almost all network layers and broadband networks have stepped into the fast developing period.Meanwhile,the development of broadband nultimedia appplications of broadband access.Broadband access and enterprise Ethernet access have started to be poputarized.while will bring huge traffic intk the constructed broadband backbone networks.Based on the new broadband network model,the development trends of core switching router,opptical transmission network,MPLS and QoS are disscussed in this paper.
