Abstract

As wired and wireless networks grow, underlying protocols need to be evaluated so that heterogeneous networks can be linked in an efficient manner. Among the transport layer protocols, user datagram protocol UDP is the only protocol that offers a fast and efficient mechanism to handle voice and video data traffic because it is a message based, connectionless service operating on the IP layer. In addition to the network conditions, it is observed that the performance also depends upon the implementation of the protocol. UNIX is one of the most widely used operating system in the networking world and different UNIX flavors have different UDP stack implementation. In this research work the performance of different UDP implementations were compared under different network conditions. It is observed that no UDP implementation dominates in all the tested network conditions. It is also observed that the selection of an appropriate datagram size had large impact on the overall performance.
UNIX用户数据报协议实现性能分析
随着有线和无线网络的发展,需要对底层协议进行评估,以便以有效的方式连接异构网络。在传输层协议中,用户数据报协议UDP是唯一提供快速有效的机制来处理语音和视频数据流量的协议,因为它是在IP层上运行的基于消息的无连接服务。除了网络条件外,可以观察到性能还取决于协议的实现。UNIX是网络世界中使用最广泛的操作系统之一,不同的UNIX风格有不同的UDP栈实现。在本研究中,比较了不同的UDP实现在不同网络条件下的性能。可以观察到,在所有测试的网络条件下,没有UDP实现占主导地位。还可以观察到,选择合适的数据报大小对整体性能有很大的影响。
