In the realm of battlefield operations, where seamless communication is paramount, the utilization of all available networking equipment is indispensable. However, the diverse array of vendor equipment often poses compatibility challenges across different transmission channels. These issues are frequently rooted in the varying limitations of packet length among the equipment, leading to undesirable packet fragmentation and potential loss. To mitigate these challenges, we have explored the efficacy of GRE (Generic Routing Encapsulation) tunnel utilization. By employing GRE methodology, we can tailor packet length to optimize performance across specific transmission media and service types. Our focus lies particularly on high-interactivity applications crucial for battlefield environments, such as file transfer and video streaming, for both encrypted and unencrypted scenarios. We present the results of comprehensive experiments that have enabled us to identify optimal configurations for various scenarios, ensuring efficient communication.
