'''Dynamic bandwidth allocation''' 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 isDynamic essentiallyBandwidth theAllocation? same thing as [[statistical multiplexing]]|url=https://www.{{disputedeasytechjunkie.com/what-inlineis-dynamic-bandwidth-allocation.htm |Mergeaccess-date=5 withFebruary statistical2024 multiplexing?|datewebsite=April 2012EasyTechJunkie}}</ref> This is a form of [[bandwidth management]], Wherewhere the sharing of a link adapts in some way to the instantaneous traffic demands of the nodes connected to the link.

Dynamic 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,all users are typically not transmittingconnected datato (orthe voice or video)network at allone timestime

# even when connected, users are not transmitting data (or voice or video) at all times

(3)# most traffic occurs in bursts -- therebursts—there are gaps between packets of information that can be filled with other user traffic

Different network protocols implement dynamic bandwidth allocation 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 is defined in the ITU G.983 specification for [[passive optical network]] (PON).
