The document presents a study analyzing the use of tunneling, compressing, and multiplexing (TCM) techniques for optimizing TCP traffic in massive multiplayer online games (MMORPGs). The study adapts the TCRTP protocol stack for use with TCP traffic from MMORPGs. Tests of the TCM approach on real game traces show bandwidth savings of up to 60% are possible, as well as reductions in the number of packets per second. Additional testing examines the impact of TCM on mean opinion score (MOS) for different levels of added delay. The results suggest avoiding large period sizes for multiplexing when round-trip times are high.
