Abstract
The increasing popularity of smartphones and other data-enabled cellular devices has led to a rapid expansion of cellular data networks worldwide. These networks are constantly being improved to provide new functionality, improved capacity, and better reliability. Optimization, testing, and troubleshooting of these systems are all important areas of concern within the cellular network industry. Large amounts of engineering resources are devoted to these topics, with the result that analysis techniques and best practices are constantly being improved. This paper details recent work regarding the analysis of cellular data device behavior in a live system, and the design of a high performance load generator to simulate this behavior for use in system testing and debugging. Internet Protocol (IP) packet capture data is analyzed using a simple graph-based analysis technique that provides a detailed characterization of device behavior. This characterization is then used in the design of a second generation high performance load generator. © 2014 Alcatel-Lucent.
测量和模拟蜂窝交换系统IP流量
智能手机和其他支持数据的蜂窝设备越来越受欢迎，导致全球蜂窝数据网络的快速扩张。这些网络正在不断改进，以提供新的功能、改进的容量和更好的可靠性。这些系统的优化、测试和故障排除都是蜂窝网络行业关注的重要领域。大量的工程资源致力于这些主题，结果是分析技术和最佳实践不断得到改进。本文详细介绍了有关实时系统中蜂窝数据设备行为分析的最新工作，以及模拟这种行为用于系统测试和调试的高性能负载生成器的设计。使用简单的基于图的分析技术来分析互联网协议（IP）数据包捕获数据，该分析技术提供了设备行为的详细表征。这种特性随后被用于第二代高性能负载发生器的设计中。®2014阿尔卡特朗讯。
