OSI-Internetworking: Realization and Performance Analysis

In this paper the implementation and performance analysis of an experimental OSI internetwork of interconnected LANs and WANs is described. In the first part, a survey of existing internetworking solutions is given, then the OSI internetwork realized is described. In the second part, methods and tools developed for the performance analysis of heterogeneous networks are introduced. This comprises the simulative modeling system NETSIM and the distributed monitoring system NETMON. These systems are also suitable for the debugging and optimizing implemented code and have been applied to the analysis and optimization of the experimental OSI internetwork.
