best effort
<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 latency 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. [Scientific American, Nov. 1994, pp. 83-84]. (1995-04-04) | ||||

Best effort delivery
Best effort delivery describes a network service in which the does not provide any guarantees that data is delivered or that a user is given a guaranteed quality of service level or a certain priority. In a best effort network all users obtain best effort service, meaning that they obtain unspecified variable bit rate and delivery time, depending on the current traffic load. By removing features such as recovery of lost or corrupted data and preallocation of resources, the network operates more efficiently, and the network nodes are inexpensive.
