Researchers crack network latency nut with new algorithm

Issues with latency and dropped packets can kill a network's performance and cripple applications like real-time communications, scientific computing, and high-frequency trading. But the problems can be extremely difficult to diagnose, as they may not appear under test conditions, and real-time monitoring of performance can require dedicated hardware or procedures that actually cut into the usable bandwidth. A team of academic researchers have come up with what they think is a solution, one that could sample the transmission of a collection of representative packets in real time, in a manner that's inexpensive in terms of both hardware and networking resources.
