Abstract

The application of protocol filtering in network modeling was discussed. This technique can be used to conduct performance analysis by simulating system "what-if" scenarios. The Windows NT and Novell Netware subnets of the School of Engineering at Widener University were considered as the problem domain. Analysis was conducted on 1.2 GB of data gathered daily over a period of two months by a network monitor. Protocol models built for NCP, SAP, RIP, IPX NetBIOS, UDP Broadcasts, TCP, Telnet, ARP, SMB, IBMNB, NetBIOS NS, AARP, RTMP, and NBP. Identification of different types of protocol traffic in association with source and destination was effected through customized packet filtering. Thereafter, traffic models were built for interarrival time and packet size. After extensive testing of the simulation output, what-if scenarios were setup and addressed. One such scenario involved the addition of ten workstations to an existing subnet. Another variant was to consider a new subnet containing ten workstations. The simulation output has been verified against an external criterion.

协议过滤:Windows NT和Novell NetWare网络建模的微观方法

讨论了协议过滤在网络建模中的应用。该技术可用于通过模拟系统“假设”场景来进行性能分析。Widener大学工程学院的Windows NT和Novell网络子网被认为是问题域。对网络监视器在两个月内每天收集的1.2 GB数据进行了分析。建立了NCP、SAP、RIP、IPX NetBIOS、UDP广播、TCP、Telnet、ARP、SMB、IBMNB、NetBIOS NS、AARP、RTMP和NBP协议模型。通过自定义包过滤，实现对源、目的关联的不同类型协议流量的识别。然后，根据到达间隔时间和数据包大小建立流量模型。在对模拟输出进行广泛测试之后，设置并处理了假设场景。其中一个场景涉及到将十个工作站添加到现有子网中。另一种变体是考虑一个包含十个工作站的新子网。仿真输出已根据外部标准进行了验证。
