区分服务在路由器中的实现

Implementation of Differentiated Services in IP Routers

随着因特网的不断发展,在传统的尽力业务之外因特网还需要支持多种其它业务类型.同时,还要保证因特网的可扩展性和稳定性.传统的综合服务方式无法同时满足上述要求.为了解决这个问题,IETF提出了区分服务方式.区分服务方式是因特网上关于服务质量的解决方案.在分析了区分服务方式所提供的各种服务类型后,给出了这些服务类型在路由器内的实现方法.

With the development of Internet, many types of services besides Best Effort Service' need to be supported with the scalability and stability of Internet to be guaranteed. The conventional Integrated Service mode can not address the above requirements. To solve these problems, IETF proposes Differentiated Services mode. Diff-Serv is the Internet solution about QoS. After the analysis of various service types provided by Diff- Serv, the implementation of these services in routers is presented.
