Design and Implementation of Background Traffic Management System In Network Scene

We design an administration system to solve the isolation problem in a multi-user shared network testbed which holds multiple background traffic generators simultaneously running in parallel experiment scenes. Traffic generators embedded in an experiment scene are dedicated to dynamically generate background traffic for that scene based on session analysis, re-stamping and recombination of the captured traffic from the real network. This administration system has been applied to a network testbed and can stably and reliably manage traffic generators in 4 parallel experiment scenes. 网络场景背景流量管理系统的设计与实现 1 刘宁逸, 龚晓锐, 霍玮 , 宋振宇 中国科学院信息工程研究所 中国科学院网络测评技术重点实验室 网络安全防护技术北京市重点实 验室,北京,中国 中国科学院大学 网络空间安全学院,北京,中国 liuningyi@iie.ac.cn, gongxiaorui@iie.ac.cn, huowei@iie.ac.cn, songzhenyu@iie.ac.cn 通讯作者 关键词: 网络测试床; 流量生成; 并发场景 中文摘要. 本文通过对真实网络流量进行会话分析、重新标记并重组,合成为背景流量,通 过网络配置解决背景流量在并发场景中的网络隔离性问题,实现网络测试床中的背景流量管 理系统,并通过4个并发场景的实验测试验证了该系统的可靠性与稳定性。 1.引言 随着互联网的高速发展,网络研究正面临一个关键问题:难以在现实网络环境中安全可 靠地测试新开发的功能 。现有的测试设施限制了开发、测试和培训的时间与资源成本,在 安全领域,面对现实世界威胁的快速演变时,这一点显得尤为不利。为了解决这一问题, 网络测试床被设计为一个提供与其他网络相隔离的、代表真实世界场景的测试台,提供实践 2nd International Conference on Advances in Energy, Environment and Chemical Science (AEECS 2018) Copyright © 2018, the Authors.
