摘要
从如何改善VoIP网关语音服务质量出发,分析了目前可行的QoS方案,并提出了一种支持区分服务的解决方案。该方案结构清晰、扩展性强,解决了VoIP网关没有服务质量控制的问题,为VoIP网关QoS模块设计与实现提供了有效的参考。该方案目前已成功运用于基于嵌入式Linux平台的VoIP网关中,能够明显改善语音的服务质量。
How to improve the voice quality of VolP gateway was presented, and the feasible solution for QoS was analyzed. Then an implementation of QoS module that supports DiffServ was proposed. The module had a dear framework and good expansibility, gave a solution to the problem that VoIP gateway without any QoS abilities, and could be used as a reference in the QoS module design and implementation of VoIP gateway. This solution has been adopted in the VoIP gateway with embedded Linux platform and it meets the quality of the voice well.
