MIT researchers are presenting a paper (next month at the annual meeting of the ACM Special Interest Group on Data Communication) on a network management system they are calling “no-wait datacenters.” The researchers have experimentally shown that the system can reduce network transmission queue length by over 99 percent.
With testing done in cooperation with Facebook — making use of one of their data center facilities — the researchers were able to show latency reductions that effectively did away with the normal queue. Their report stated that even in times of heaviest traffic, the average latency per request dropped from 3.56 microseconds to .23 microseconds.
