Abstract : We describe the physics analogies used in a model of latency in computer communication and protocols. The communication model describes state imprecision as induced by message latency, and is based on physical models of particle interaction. Virtual particle effects are emulated through the use of conditional messages that reduce perceived latency while requiring additional bandwidth and active sender participation....
