This attribute specifies the ATM service category for both directions
of the connection.
The value derivedFromBBC may only be used if the SrcPvc
component is provisioned under this Vcc. Otherwise a specific
ATM service category must be specified.
If this attribute is set to derivedFromBBC, the Broadband Bearer
Capability (BBC) and bestEffort attributes are used to determine the
atmServiceCategory of this connection.
If this attribute is set to other than derivedFromBBC, the value of
this attribute is used to override the provisioned BBC Information
Element parameters. In those cases, the BBC attributes are not used.
The constantBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. The consistent availability of a fixed quantity of
bandwidth is considered appropriate for CBR service. Cells which
are delayed beyond the value specified by Cell Transfer Delay are
assumed to be of significantly reduced value to the application.
The rtVariableBitRate service category is intended for real time
applications, that is those requiring tightly constrained delay and
delay variation, as would be appropriate for voice and video
applications. Sources are expected to transmit at a rate which varies
with time. Equivalently, the source can be described as 'bursty'.
Cells which are delayed beyond the value specified by CTD are
assumed to be of significantly reduced value to the application. Real
time VBR service may support statistical multiplexing of real time
sources.
The nrtVariableBitRate service category is intended for non-real
time applications which have bursty traffic characteristics and which
can be characterized in terms of a PCR, SCR, and MBS. For those
cells which are transferred within the traffic contract, the application
expects a low cell loss ratio. For all connections, it expects a bound
on the mean cell transfer delay. Non-real time VBR service may
support statistical multiplexing of connections.
The availableBitRate service is an ATM layer service category for
which the limiting ATM layer transfer characteristics provided by
the network may change subsequent to connection establishment.
ABR service has a flow control mechanism which supports several
types of feedback to control the source rate in response to changing
ATM layer transfer characteristics. ABR service is not intended to
support real-time applications.
The unspecifiedBitRate service is intended for non-real time
applications; that is, those not requiring tightly constrained delay
and delay variation. UBR sources are expected to be bursty. UBR
service supports a high degree of statistical multiplexing among
sources. UBR service does not specify traffic related service
guarantees. No numerical commitments are made with respect to
the cell loss ratio experienced by a UBR connection, or as to the
cell transfer delay experienced by cells on the connection.
