Current implementations of TCP suffer from performance problems like bias against flows with higher Round Trip Times (RTTs), synchronization of windows, phase effects in flows and correlated losses leading to throughput degradations with Drop Tail queues. This paper proposes a solution to these issues by introducing randomization into the network through end-to-end congestion control protocols. Instead of sending back-to-back packets, Randomized TCP spaces successive packet transmissions with a time interval. Randomized TCP, by introducing randomization in the network, reduces synchronization, phase effects and bias against bursty traffic and longer RTT flows, prevalent with current implementations of TCP and Drop Tail Gateways.
