【摘要】：TCP/IP协议架构是目前网络的基础,其中端主机负责网络中传输流量的相关控制,包括重传、接收端的排序,以及网络拥塞控制等,而互联网只是传输渠道,只负责数据的传递。在端主机侧进行相关网络性能参数的收集、处理和分析,具有比较大的局限性,因为这些参数只能反映端主机侧的局部网络信息。整体网络的探测才是具有实际意义的,因为可以根据网络详细数据进行后续的网络优化决策。双向主动测量协议TWAMP (Two-Way Active Measurement Protocol)定义了一种测量方法,它能探测任意两台支撑这项准则的设备之间的往返IP性能。运用TWAMP,能够有效地测量传输的完整IP性能。本文针对运营商机房业务场景下的特定需求,设计了一种便携式嵌入式IP网络性能测试系统,由探针端和服务器交互进行工作。探针端用于监测运营商网络性能的各项参数。远程服务器实现整个监测系统的可视化呈现和管理。本文的主要工作内容包括： 1.对便携式IP网络性能测量系统进行需求分析,并提出嵌入式平台系统架构。 2.探针节点设计：针对TWAMP双向主动探测协议进行流程分析,并进行流程建模,将整个系统进行功能模块的划分,实现系统解耦,为后续实现带来便利。 3.网络传输性能参数的测量与分析：基于TWAMP协议的探针端应用软件的开发,包括Socket编程,端口监听,发送测量结果等功能。 4.在实验室内网环境下,分别对探针端网络测量程序和服务器端控制服务器程序进行了测试,利用网络探针系统进行应用层性能测试,验证了必备的功能及性能指标。实验表明,本文所实现的便携式IP网络性能测试系统能够有效地对网络状况进行探测,支持有效的可视化界面管理,能够稳定持续工作的时间达到48小时以上,能够支持TCP、UDP业务。
[Abstract]:The TCP/IP protocol architecture is the foundation of the current network, in which the end host is responsible for the related control of the transmission flow in the network, including retransmission, sorting of the receiving end, and network congestion control, and the Internet is only the transmission channel. Only responsible for the transmission of data. The collection, processing and analysis of the network performance parameters on the end host side have great limitations, because these parameters can only reflect the local network information on the end host side. The detection of the whole network is of practical significance because the subsequent network optimization decision can be made according to the detailed data of the network. The bidirectional active measurement protocol (TWAMP) (Two-Way Active Measurement Protocol) defines a measurement method that detects the round-trip IP performance between any two devices that support this criterion. Using TWAMP, can effectively measure the complete IP performance of transmission. In this paper, a portable embedded IP network performance testing system is designed to meet the specific requirements of the business scenario of the operator's computer room, which is interacted by the probe and the server. The probe is used to monitor the network performance parameters of the operator. The remote server realizes the visualization and management of the whole monitoring system. The main contents of this paper are as follows: 1. The requirement of portable IP network performance measurement system is analyzed, and the embedded platform system architecture is proposed. 2. Probe node design: the TWAMP bidirectional active detection protocol flow analysis and process modeling, the whole system is divided into functional modules to achieve system decoupling, which brings convenience for subsequent implementation. 3. Network transmission performance parameter measurement and analysis: the development of probe terminal application software based on TWAMP protocol, including Socket programming, port monitoring, sending measurement results and other functions. 4. The network measurement program and the server control server program on the probe side are tested in the laboratory inner network environment. The application layer performance test is carried out by using the network probe system, and the necessary function and performance index are verified. Experimental results show that the portable IP network performance testing system can effectively detect the network condition, support effective visual interface management, can work steadily and continuously for more than 48 hours, and can support TCP,. UDP service.
