ATM Service Categories
Typical Use
UBR
Best-effort service intended for non-real-time bursty applications that do not require a guarantee of traffic
characteristics such as bandwidth, cell delay, and cell delay variation.
characteristics such as bandwidth, cell delay, and cell delay variation.
UBR+
Provides a guaranteed frame rate (GFR) service with single leaky bucket algorithm; provides the ability to reserve
UBR bandwidth minimum, or specify bandwidth maximum; similar to VBR in that it increases the minimum cell rate
(MCR) when cell rate falls below the MCR.
UBR bandwidth minimum, or specify bandwidth maximum; similar to VBR in that it increases the minimum cell rate
(MCR) when cell rate falls below the MCR.
VBR-rt and VBR-nrt
Intended for applications that have bursty traffic patterns but require a guarantee of some traffic parameters; a peak
cell rate (PCR), sustained cell rate (SCR), and maximum burst size (MBS) can specify traffic parameters.
cell rate (PCR), sustained cell rate (SCR), and maximum burst size (MBS) can specify traffic parameters.
ABR
Employed to maximize bandwidth use of the ATM link by using congestion feedback notification (resource
management cells); both PCR and MCR specify the ABR connection; the transmit rate of each connection is flow-
controlled such that the rate is always between the user-specified values for a minimum and peak rate.
management cells); both PCR and MCR specify the ABR connection; the transmit rate of each connection is flow-
controlled such that the rate is always between the user-specified values for a minimum and peak rate.
CBR
Intended for real-time applications such as Systems Network Architecture (SNA) traffic, voice, and video, which
require a fixed bandwidth and low cell delay; CBR in initial release supports data only.
