摘　　要：多业务运营已经成为新时期运营商发展的趋势。在城域网领域,随着业务类型的多样化、业务流向/流量不确定性的增加,如何有效地标识用户/业务、提供完善的QoS机制成为多业务发展的关键。针对城域网现存的问题,电信级以太网技术通过多种增强技术(如ERP、QinQ、QoS、电信级网管等)为城域网提供完备的QoS机制和电信级性能。从多业务运营的需求出发,分析现网存在的问题和解决方式,剖析电信级以太网技术在满足城域网优化(特别是QoS提供)方面的特点,并最后对其发展趋势作出判断。Multi-Services Operation has now become the main development trend of the Carriers. In the MAN area, with the diversification of services and uncertainty of service flow direction / traffic volume, how to identify the users / services efficiently and provide comprehensive QoS mechanism is now the key for multi-services development. To solve the existing problems of MAN, Carrier Ethernet provides completed QoS package and carrier grade performance via multiple Ethernet-enhanced technologies （e.g. ERP, QinQ,QoS,Carrier Grade NM）.From the requirement of Multi-Services Operation, this article analyzes the existing problems and solution to current MAN, and parses the characters of Carrier Ethernet in satisfying the MAN optimization （especially for QoS providing）, and at the end makes a judgment to the prospect of Carrier Ethernet.
