'''Dynamic Bandwidthbandwidth Allocationallocation''' (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.<ref>{{Cite Thisweb is|last=Tatum a|first=Malcolm form|date=18 ofJanuary [[bandwidth2024 management]],|title=What andIs Dynamic Bandwidth Allocation? |url=https://www.easytechjunkie.com/what-is-dynamic-bandwidth-allocation.htm essentially|access-date=5 theFebruary same2024 thing|website=EasyTechJunkie}}</ref> asThis is a form of [[statisticalbandwidth multiplexingmanagement]]., Wherewhere the sharing of a link adapts in some way to the instantaneous traffic demands of the nodes connected to the link.

DBADynamic bandwidth allocation 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

(1)# all users are typically not connected to the network at one time

Different network protocols implement DBA in different ways. These methods are typically defined in [[Standardization|standard]]s 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]]).
