Dynamic Bandwidth Allocation (DBA) is a technique by which traffic bandwidth in a shared telecommunications medium can be allocated on demand and fairly between different users of that bandwidth. Essentially, it is bandwidth management or is also sometimes known as statistical multiplexing. Where the sharing of a link adapts in some way to the instantaneous traffic demands of the nodes connected to the link.
DBA takes advantage of several attributes of shared networks: (1) all users are typically not connected to the network at one time (2) even when connected, users are not transmitting data (or voice or video) at all times (3) most traffic is "bursty" -- there are gaps between packets of information that can be filled with other user traffic
Different network protocols implement DBA in different ways. These methods are typically defined in [standards] developed by standards bodies such as the ITU, IEEE, FSAN, or IETF. One example of DBA is defined in the ITU G.983 specification for passive optical network (PON). This article is about the location. ... The Institute of Electrical and Electronics Engineers or IEEE (pronounced as eye-triple-ee) is an international non-profit, professional organization incorporated in the State of New York, United States. ... The Internet Engineering Task Force (IETF) is charged with developing and promoting Internet standards. ... A Passive Optical Network (PON) is a point-to-multipoint, fiber to the premises network architecture in which unpowered optical splitters are used to enable a single optical fiber to serve multiple premises, typically 32. ... In the fictional Animorphs universe, the Pon are a species that are mentioned in passing in #26-The Attack and were not brought up again. ...
