| 摘 要： | 针对移动IP网络，由于资源有限、有效带宽不可预测、差错率高等原因造成的QoS（Quality of Serv-ice）问题，提出了在移动IP网络中的QoS保证方法。该方法将资源预留协议（RSVP：Resource Reservation Protocol）和区分服务（DiffServ：Differentiated Services）协议相结合，采用映射技术，实现了在移动IP上提供端到端的QoS保证机制，从而解决了传统移动IP网络中端到端通信时扩展性差的问题，与原有网络相比，其通信质量提高了30％。

| Abstract: | In mobile IP network, the limited resources, effective bandwidth unpredictability, and higher error rate causes QoS （Quality of Service） issues. QoS guarantee methods ware provided in the mobile IP nerwork. This method combined the RSVP （Resource Reservation Protocol） with the DiffServ （Differentiated Services） protocol technology, and this method achieved in the end-to-end QoS mechanisms of the mobile IP network. It resolved the poor expansionary issue of the end-to-end communication in the traditional IP network. Compared with the original network, the communication quality increased by 30%. This method adopts the mapping technology. It is simple, effective and low in cost. It is valuable for the network research engineer. |
