关于IP QoS的技术研究

目的分析研究基于IPV4网络对于服务质量QoS要求的无法满足,探讨解决方案和IPQoS的发展方向。方法利用IFTE提出的集成服务IntServ模型,区分服务DiffServ模型,多标签交换协议,流量工程,IEEE 802.1p,子网带宽管理,实时协议。结果提高IPV4网络对于服务质量QoS要求的保证,使网络能够灵活根据业务的具体特点,提供满足QoS要求的服务。结论未来网络的发展将是围绕着MPLS技术展开的。在网络上层,DiffServ和MPLS相结合,DiffServ将业务分类、整形、聚合,MPLS再将处理过的数据转换成不同的标签进行转发。在网络底层,MPLS直接与WDM光网络技术相结合,从而实现更快、更智能的数据传送。

Technology research on IP QoS

Aim To analyze and study what based on the quality of service required by QoS can't be satisfied by the network of IPV4,discuss about the solution to it and developing trend of IP QoS.Methods Make use of IntServ model presented by IFTE and distinguish among DiffServ model,multi protocol label switching,traffic engineering,IEEE802.LP,subnet bandwidth management and real time transport protocol.Results Improve the guarantee of the request for the quality of service by the network of IPV4,make it offer satisfactory service according to the detailed characteristic of different business.Conclusion The future trend of network will develop on the basis of the technology of MPLS.On the top of the network,combine DiffServ with MPLS,service will be classified,repaired and assembled by DiffServ;MPLS will turn processed data into different label and forward.At the bottom layer,MPLS and WDM are combined with each other directly to make data transmission more rapid and more intellectual.
