基于SSH协议的网络损伤调度系统

Network Impairment Dispatching System Based on SSH Protocol

随着互联网技术的迅速发展,计算机通信网设计规模也在逐步扩大,数据量正以爆炸性的趋势增长着。在这种环境下,通信与业务融合发展的方式应运而生,这一点说明通信网络的数据交互效率与传输质量开始与业务需求紧密相关。真实网络往往规模庞大,结构复杂,如何设计一个低成本、高可靠的仿真平台来对网络结构与性能进行模拟仿真成为研究的难点。对此,提出了一种基于SSH协议的网络损伤调度系统,用Linux内核的Netem模块模拟网络损伤,并对仿真保真度进行评估,通过SSH技术连接多个网络损伤仪,实现多损伤仪的远程调度管理,安全高效,控制灵活。

With the rapid development of Internet technology,the design scale of computer communication network is gradually expanding,and data size is growing explosively.In this situation,the way of communication and service integration comes into being,which shows that the efficiency of data exchange and transmission quality of communication network are closely related to the service requirements.The real network always has large scale and complex structure.How to design a low-cost and high-reliable simulation platform to simulate the network structure and performance has become the difficulty of research.In this paper,a network impairment dispatching system based on SSH protocol is proposed.The netem module of Linux kernel is used to simulate the network impairment,and the simulation fidelity will be evaluated.SSH protocol is used to connect multiple network impairment emulators to realize the remote dispatching management of multiple impairment emulators,which is safe,efficient and flexible.
