5.10.3 Add a VCC
To add a VCC entry, complete the following steps:
STEP 1: Click on the Add VCC button, the VCC screen will appear.
STEP 2: Enter values for the parameters (explained below).
STEP 3: Click the Apply button at the bottom of the page.
vpi: Virtual Path Identifier (VPI) that identifies this ATM
connection. The vpi is integer numbers, which can range
from 0 to 4095.
vci: Virtual Channel Identifier (VCI) that identifies this ATM
connection. The vci is an integer number which can range
from 0 to 65,535.
Peak Cell rate
(cells/sec):
Defines the fastest rate a user can send cells to the network.
It is expressed in units of cells per second.
Average Cell rate
(cells/sec): Defines the maximum sustainable/average rate a user can
send cells to the network. It is expressed in cells per second.
This specifies the bandwidth utilization. This value must
always be less than or equal to the Peak Cell Rate.
Burst size (cells): Maximum number of cells the user can send at the peak rate
in a burst, within a sustainable rate.
CDVT (cells): Constrains the number of cells the user can send to the
network at the maximum line rate.

Rate:
Supports real-time applications requiring a fixed amount 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.
Supports time-sensitive applications such as voice. In these
applications the rate at which cells arrive are varied.
Supports applications that have no constraints on delay and
delay variation, but still have variable-rate and bursty traffic
characteristics.
Best effort service that does not require tightly constrained
delay and delay variation. UBR provides no specific quality of
service or guaranteed throughput.
