设计与实现一种面向协议栈特征的测试程序

Design and implementation of a test program oriented to protocol stack characteristic

针对传统的测试工具难以全面包含通信协议栈特征的问题,基于用户数据报协议的数据传输算法,设计并实现了一种能够全面体现协议栈特征的测试程序.该程序由用户侧的基准程序和基站侧的基站协议栈软件两部分构成,综合考虑了实际协议栈中需要维护的数据信息与特征,从而对基站接收上行数据进行模拟,最终在虚拟化平台中对程序进行实验测评.实验结果表明,该程序能够在虚拟化平台中模拟协议栈的上行数据流,并能够基本反映出数据流的特征.

Aimed at the problem that the traditional test tools can hardly include the full characteristics of communication protocol stack and based on data transmission algorithm of user datagram protocol, a test program which can fully embody the characteristics of protocol stack is designed and implemented. This program consists of both the user-side benchmark program at user’s end and base station protocol stack software, at base-station end and takes the data information and characteristic, which need to be maintained in the actual protocol stack, into comprehensive consideration, so that the upstream data received by the base station will be simulated and finally, the program will be evaluated on virtualization platform. The experimental results show the proposed program can be used to simulate the protocol stack upstream data on the virtualization platform, and basically reflect the characteristic of the data-stream.
