下一代网络8端口交换机体系结构设计

摘要

In order to meet the demand for customer premises multiple terminal service on next generation of cable TV network, customer premises 8-port switchboard is built, and the internal structure of topological and its internal bandwidth are designed. According to the different needs of multiple business, each port specific bandwidth is confirmed. Using OPNET simulation software to simulate has shown that this 8-port switchboard well meets the requirements of users and techniques, which can guarantee the more effective transmission between backbone transmission network and customer premises for next generation cable TV network.%为了满足下一代有线电视网络对驻地用户多终端服务的要求,构建用户驻地8端口交换机,设计交换机内部拓扑结构和交换机内部的带宽配置,根据多种业务的不同需求,确定每个端口特定的带宽.借助OPNET仿真软件进行仿真,结果表明,该8端口交换机很好地满足了技术指标的要求和用户业务的需求,从而保证了下一代有线电视网络在骨干传送网和用户驻地之间更加有效的传输.
