best effort definition networking
A classification of low priority network traffic, used especially the Internet
Different kinds of traffic have different priorities. Videoconferencing
and other types of real-time
communication, for example, require a certain minimum guaranteed bandwidth
and so must be given a high priority. Electronic mail
, on the other hand, can tolerate an arbitrarily long delay and is classified as a "best-effort" service.
