VBR: Variable Bit Rate
Variable Bit Rate (VBR) is a QoS class defined by the ATM Forum for ATM networks. VBR is subdivided into a realtime (RT) class and non-realtime (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.
