Definition
Enter the priority to be assigned to frames
received on this PVC as they are passed
onto the local VLAN segment. The valid
range is 0 - 7.
Note:
This is a non-editable field for
information only.
Displays the traffic class for the set you are
creating. Values include:
• UBR - Unspecified bit rate which is
characterized in terms of Cell Delay
Variation Tolerance (CDVT), and
Peak Cell Rate (PCR).
• CBR - Constant bit rate. This class is
used by a connection that requests a
static amount of bandwidth that is
continuously available during the
lifetime of the connection. This
amount of bandwidth is
characterized in terms of PCR, and
Cell Delay Variation Tolerance
(CDVT).
• rtVBR - Real-time variable bit rate.
This class is intended for real-time
applications (voice and video).
rtVBR connections are characterized
in terms of PCR, SCR, and MBS.
• nrtVBR - Non-real-time variable bit
rate. This class is intended for non-
real-time applications that have
bursty traffic characteristics and are
characterized in terms of PCR,
Sustainable Cell Rate (SCR), and
Maximum Burst Size (MBS).
Enter the Cell Delay Variation Tolerance.
When cells from two or more connection
are multiplexed, cells of a given
connection may be delayed.
Simultaneously, cells of another
connection are being inserted at the
output of the multiplexer. Some
randomness may affect the inter-arrival
time between consecutive cells of a
connection. The upper boundary on this
delay is the CDVT.
