15.6.2.2 Fairness-based Allotment of Unused and Unbudgeted Bandwidth
The following table shows the amount of bandwidth that each class gets.

Table 88 Fairness-based Allotment of Unused and Unbudgeted Bandwidth Example

BANDWIDTH CLASSES AND ALLOTMENTS
Root Class: 10240 kbps
Suppose that all of the classes except for the administration class need more bandwidth.
• Each class gets up to its budgeted bandwidth. The administration class only uses 1024
kbps of its budgeted 2048 kbps.
• The P-660HWP-Dx divides the total 3072 kbps total of unbudgeted and unused bandwidth
equally among the other classes. 1024 kbps extra goes to each so the other classes each get
a total of 3072 kbps.

15.6.3 Bandwidth Management Priorities

The following table describes the priorities that you can apply to traffic that the P-660HWP-
Dx forwards out through an interface.

PRIORITY LEVELS: TRAFFIC WITH A HIGHER PRIORITY GETS THROUGH FASTER WHILE
TRAFFIC WITH A LOWER PRIORITY IS DROPPED IF THE NETWORK IS CONGESTED.

15.7 Over Allotment of Bandwidth

You can set the bandwidth management speed for an interface higher than the interface's
actual transmission speed. Higher priority traffic gets to use up to its allocated bandwidth,
even if it takes up all of the interface's available bandwidth. This could stop lower priority
traffic from being sent. The following

Actual outgoing bandwidth available on the interface: 1000 kbps
Root Class: 1500 kbps (same
as Speed setting)
P-660HWP-Dx User's Guide
Administration: 1024 kbps
Sales: 3072 kbps
Marketing: 3072 kbps
Research: 3072 kbps
Typically used for voice traffic or video that is especially sensitive to jitter (jitter
is the variations in delay).
Typically used for "excellent effort" or better than best effort and would include
important business traffic that can tolerate some delay.
This is typically used for non-critical "background" traffic such as bulk
transfers that are allowed but that should not affect other applications and
users.
is an example.
VoIP traffic (Service = SIP): 500 Kbps
NetMeeting traffic (Service = H.323): 500 kbps
FTP (Service = FTP): 500 Kbps
