A client, server codes were developed using FreeBSD. This is a step before analyzing the Architectures of VoIPv6 in the current internet in order for it to cope with IPv6 traffic transmission requirements in general and specifically voice traffic, which is being attracting the efforts of research, bodes currently. These tests were conducted in the application level without looking into the network level of the network. VoIPv6 performance tests were conducted in the current tunneled and native IPv6 aiming for better end-to-end VoIPv6 performance. The results obtained in this study were shown in deferent codec's for different bit rates in Kilo bits per second, which act as an indicator for the better performance of G.711 compared with the rest of the tested codes.展开更多

文摘针对Mobile IPv6协议实现的产品可能存在与协议说明不一致的问题,对Mobile IPv6展开协议一致性测试。首先根据RFC 3775提取了Mobile IPv6的一致性测试需求,并针对协议特点设计一种主被动测试相结合的新测试方法,然后运用有限状态机模型为移动节点、家乡代理和通信节点创建形式化模型,在该模型基础上使用U方法自动生成了14条测试例。最后,对Red Hat Linux 9.0环境下的mipv6-1.1-v2.4.26协议实现进行一致性测试实践。对测试结果进行分析后表明,被测实现与协议说明之间存在不一致之处。
