Performance analysis of packet bundling techniques in DIS

With the increasing complexity and scale of the simulation, meeting the communication and bandwidth requirements has become a major challenge in the design and implementation of Distributed Interactive Simulations (DIS). In this paper, we will study some packet bundling mechanisms as an important technique in reducing the packet transmission rate and bandwidth requirement at the gateway in a DIS environment. Two packet bundling mechanisms are proposed. One uses a multilevel priority queue, and the other a single priority queue. Simulation results show that using a packet bundling technique can effectively reduce the average packet transmission rate and average transmission bandwidth requirement while maintaining the real-time constraints for the packets
