VBR (variable bit rate): QoS class defined by the ATM Forum for
ATM networks. VBR is subdivided into a real time (RT) class and
non-real time (NRT) class. VBR (RT) is used for connections in which
there is a fixed timing relationship between samples. VBR (NRT) is
used for connections in which there is no fixed timing relationship
between samples, but that still need a guaranteed QoS. Compare
with ABR, CBR, and UBR.
