The learning environment uses the source code availability of the Linux operating system as a case study of the implementation issues and ramifications of internet networking infrastructures. Laboratory use of experimentation with internetworking equipment and software allows interaction with internetworking principles and fundamentals as well as implementation and performance issues. The objectives of this environment include providing a comprehensive mechanism whereby students are exposed to fundamentals and principles that may readily be applied to experimental-based internetwork research and internetwork product development. A follow-on capstone design environment is also briefly described. <br/> <br/>Description: ©2003 IEEE. Personal use of this material is permitted.

(Mostafa Hamed); Fujimoto, Richard M. <br/> <br/>Abstract: The memory resources required by network simulations can grow quadratically with size of the simulated network. In simulations that use routing tables at each node to perform per-hop packet forwarding, the storage required for the routing tables is O(N2), where N is the number of simulated network nodes in the topology. Additionally, the CPU time required in the simulation environment to compute and populate these routing tables can be excessive and can dominate the overall simulation tame. We propose a new routing technique, known as Neighbor-Index Vectors, or NIx-Vectors, which eliminates both the storage required for the routing tables and the CPU time required to compute them. We show experimental results using NIx- Vector routing in the popular network simulator ns. With our technique, we achieve a near order of magnitude increase in the maximum size of a simulated network running ns on a single workstation. Further, we demonstate an increase of two orders of magnitude in topology size (networks as large as 250,000 nodes) by using this technique and running the simulation in parallel on a network of workstations. <br/> <br/>Description: ©2000 IEEE.

(Mostafa Hamed); Fujimoto, Richard M. <br/> <br/>Abstract: We introduce and discuss a methodology for heterogeneous simulations of computer networks using the dynamic simulation backplane. This methodology allows for exchanging of protocol information between simulators across layers of the protocol stack. For example, the simulationist may wish to construct a simulation using the rich set of TCP models found in the ns network simulator, and at the same time using the highly detailed wireless MAC models found in the GloMoSim simulator. The backplane provides an interface between heterogeneous simulators which allows these simulators to exchange meaningful information across layers of the protocol stack, without detailed knowledge of internal representation in the foreign simulator. With this method of heterogeneous simulation, new and experimental protocols can be validated and tested in conjunction with existing and accepted simulations of lower protocol layers. We discuss the particular problems presented by the split protocol stack model, and present our solutions. We give results of our implementation of the split protocol backplane, using the ns simulator for the higher protocol stack layers, and the GloMoSim simulator for the lower layers. <br/> <br/>Description: ©2001 IEEE.
