ISO/OSI + TCP/IP hybridโฑ๏ธ realโ€‘time jitter compensation

Data communications = information theory + physical transport + software-defined reliability. This 4000โ€‘line simulation engine lets you manipulate delivery, accuracy, delay, jitter and observe packetโ€‘level behaviour, topology scaling, and fullโ€‘duplex dynamics.
