Technology Review: Faster File Flow

"In order to be smooth, which is what FastTCP does, you have to be more gentle and assess queuing delay," says Aleksandar Kuzmanovic, an associate professor in the department of electrical engineering and computer science at Northwestern University who researches TCP. By keeping the transfer from reaching the point of packet loss, he says, it's possible to avoid sending bursts of data, which can create a jittery effect for the recipient.
