Abstract: This study discusses the design and simulation of an e-learning computer network topology based on Grid computing technology for Indonesian schools called the Indonesian Education Grid (abbreviated as IndoEdu-Grid). The usage of such a grid has its advantages such as supporting the use of heterogeneous resources (hardware or software) and resources sharing. The establishment of such network without Grid computing capabilities will lead to redundancies of the idle resources. The simulation which is built using GridSim toolkit will handle the proposed two conditions or scenarios that have different network topologies based on their routers and links configuration. Each scenario will be run in the simulator using two packet scheduling algorithms, one will be FIFO (First In First Out) Scheduler and the other SCFQ (Self-Clocked Fair Queuing) Scheduler. The processing time of the jobs packets will be evaluated to determine the most effective network topology for IndoEdu-Grid. The simulation result showed that if SCFQ scheduling algorithm is used then the most appropriate network topology is the topology which allows its packets with the same priorities to have less possibility to collide one another in one router or link which is the first scenario. The simulation results also showed that SCFQ scheduling algorithm can reduce the packets lifetime at routers that have very crowded traffics. This fact implies to the decrease of the whole job processing time.
