Design of OMNET++ for Input-queued switching Networks

To evaluate the performance of iterative scheduling algorithms in input queuing and switching networks, this study constructs a specialized simulation platform using OMNET++ software suit. Adopted through a modular and object-oriented approach, the platform supports various scheduling algorithms and can accurately simulate the complete process from data generation to output, including the processing of different types of service flows. By implementing the iSLIP, DRRM, EiSLIP and EDRRM algorithms, the platform's network-level performance simulation capability is verified under different load conditions, demonstrating its potential in promoting the research of network architecture optimization and scheduling strategies, which is of great significance in promoting the theoretical and practical advancement of network technology. This platform fills the gap of existing simulation software in specific areas and provides an effective tool for the research of iterative scheduling algorithms.
