摘要

电信传输网透明、可靠、高效地承载汇聚后的通信信息，从而全面支持通信服务提供商的各种业务并为网络层（IP、以太网、ATM、TDM等）提供服务。光学技术的发展对于实现可扩展性和高性价比的电信业务一直发挥着重要作用，同时这些技术与外部驱动力的结合将会对下一代传输网络的形成起到至关重要的作用。讨论了网络转型的驱动力，给出了未来网络架构及传输网将如何改变的愿景，并对作为网络转型核心的网络属性和相关的技术发展方向进行了论述。

Abstract

Telecommunications transport networks carry aggregated communications information transparently

reliably and efficiently

supporting a full range of communications service provider（CSP）services and service networking layers （IP

Ethernet

ATM

TDM

etc.）. While optical-specific technology advances will continue to be essential for continued scalability and cost/bit advances

it is asserted here that a combination of external drivers will have the greatest impact on shaping the form of the next generation of transport networks. The converging drivers for change were discussed

a vision of how the broader network architecture as well as transport networks change was laid out

and the changing network attributes and technology directions central to this transformation were illustrated.
