Description of Work: 


TCP has been used in the Internet for 30 years. Despite of its success, it has shown the sign of strain. Previously used feedback control falls short of providing what we want, in particular the necessity to handle the dynamics of traffic. Network community starts to worry about this but has not come out with a rescue. This research aims to build a stochastic model that considers the impact of feedback delay on the addictive increase and multiplicative decrease used by TCP, and investigate the degree of the impact on the resource utilization, transmission rate, transport latent, jitter, etc. The findings will lead to a proposal of a new protocol.
