The default parameters should be correct to match the system used by your ISP
•
Multiplexing Method - Your ISP will indicate whether your Multiplexing Method is VC-
BASED or LLC-BASED.
•
Virtual Circuit - Your ISP will indicate which VPI/VCI combination is used for your service.
Connection service guarantees are specified per ATM VPI/VCI by a set of measurable connection
parameters. Please check your ISP to set the proper parameters. If you don't know how to configure
them, please keep them as default.
•
UBR (Unspecified Bit Rate): The protocol that provides spare bandwidth to non-critical
services such as file transfers. The actual rate depend on the bandwidth of the current
network.
•
CBR(Constant Bit Rate): Real-time connection with a specified amount of guaranteed
bandwidth (PCR) that is continuously available during the connection life-time.
•
VBR-rt (Real-Time Variable Bit Rate): Similar as CBR intended for real-time applications
with constrained delay and delay variation values, but which can benefit from variable bit-
rates. The average guaranteed bandwidth is SCR, but data up to PCR may be sent for a
limited amount of data specified by MBS. A VBR-rt connection is characterized by PCR,
SCR, MBS.
•
VBR-nrt (Non-Real-Time Variable Bit Rate): Intended for non-real-time applications that
have bursty traffic characteristics and no strict transfer delay requirements but which require
an amount of guaranteed bandwidth. A VBR-nrt connection is characterized by an average
guaranteed bandwidth (SCR) up to a maximum guaranteed bandwidth (PCR) for a burst
with specified maximum size (MBS).
•
PCR (Peak Cell Rate): Maximum number of ATM cells per second that may be sent on the
connection.
•
SCR (Sustainable Cell Rate): Average number of ATM cells per second that may be sent on
the connection.
•
MBS (Maximum Burst. Size): Maximum number of ATM cells that may be sent in a burst,
and thus exceeding the average number of cells (SCR) up to the maximum number of cells
(PCR) for a limited number of ATM cells defined by MBS.
