摘要
陈述了传送网面临着机遇和挑战,提出完善的传送网在QOS、安全、技术选择等方面需满足长远发展的要求.分别讨论了城域波分和MSTP两种技术在城域传送网中的应用.通过对这种组网方式的分析,说明了城域波分+路由器技术将逐步取代路由器光纤直驱组网方式,成为未来城域核心网的主流建网模式,而MSTP将是未来城域接入网的优选方案.
The presentation of the transmission network with both opportunities and challenges,to improve the transmission network in QOS,security,technology choices,and other areas need to meet the requirements of long-term development. The two technology of M-DWDM and MSTP are discussed about the application in the MAN transmission network. Networking Method Through this analysis shows that fiber straight drive routers Networking Method will be gradually replaced by D-DWDM+router technology and it become the metro core network model of mainstream network building,and MSTP will be the optimization program in the future Metro Access Network
