“This is stuff the big traders will be interested in,” said George Varghese, a computer science professor at the UC San Diego Jacobs School of Engineering and an author on the SIGCOMM paper, “but more importantly, the router vendors for whom such trading markets are an important vertical.”
That "stuff" is an inexpensive solution for diagnosing delays in data center networks as short as tens of millionths of seconds—delays that can lead to multi-million dollar losses for investment banks running automatic stock trading systems. Similar delays can delay parallel processing in high performance cluster computing applications run by Fortune 500 companies and universities.
University of California, San Diego and Purdue University computer scientists presented this work on August 20, 2009 at SIGCOMM, the premier networking conference.
The new approach offers the possibility of diagnosing fine-grained delays—down to tens to microseconds—and packet loss as infrequent as one in a million at every router within a data center network. (One microsecond is one millionth of a second.) The solution could be implemented in today’s router designs with almost zero cost in terms of router hardware and with no performance penalty. The UC San Diego and Purdue University computer scientists call their invention the Lossy Difference Aggregator.
