Service Type:

 

cbr (Constant Bit

Supports real-time applications requiring a fixed amount

Rate)

of bandwidth. The applications produce data at regular

 

intervals such as a video stream. The user can specify how

 

much bandwidth they wish to reserve.

rtvbr (Real Time

Supports time-sensitive applications such as voice. In

Variable Bit Rate)

these applications the rate at which cells arrive are varied.

Nrtvbr (Non-Real

Supports applications that have no constraints on delay

Time Variable Bit

and delay variation, but still have variable-rate and bursty

Rate)

traffic characteristics.

Ubr (Unspecified Bit

Best effort service that does not require tightly constrained

Rate)

delay and delay variation. UBR provides no specific quality

 

of service or guaranteed throughput.
