Note: At this time, the global burst parameters are not persistent, meaning you will need to
put a command in the startup file (Autostart File) if you want them to stick between re-
boots. You need to add this line to the bottom of the Autostart File.
To edit the Autostart File:
From the Maintenance and Reference Menu,
Click on ->
Maintenance
->
[
Edit
Autostart File
]
.
Add the SAME line that you created above at the bottom of
the Autostart File to change your global burst parameter settings. For our
example,
type in:
/usr/sbin/brctl/
setburstparams my 40 30
Bursting and Speed Tests
With the default settings of 10 second bursts and an 80 second time out before the next
burst, it is unlikely a user will be able to see their full burst speed accurately with a speed
test site. The easiest way would be to extend the burst time to minutes, instead of the
default 10 seconds, and then run the speed test.
With the default set at 10 seconds, the best way to see a burst in action is to take a
continuous snap shot
of an IP’s consumption during an extended download.
Note: Before you implement bursting, you may want to consider the downside of bursting.

Setting up Bandwidth Pools
(
back
)
A Bandwidth Pool is a collection of IP addresses that
share
a bandwidth
allocation. Once IP addresses are contained within a bandwidth pool, the sum
total of bandwidth for all the IP addresses will not be allowed to exceed more than the total
bandwidth allocated to the bandwidth pool. For example, if four IP addresses are set in a
pool, and the pool bandwidth is set at 1Mbps, then the total bandwidth for all four IPs is
1Mbps (the total, not per IP).
Pools are a bandwidth restriction, not a reservation.
Think of a pool as a "
virtual NetEqualizer
". You can group users into logical trunks by IP
address and apply
equalizing technology
to each logical group (bandwidth pool). For the
example above, equalizing will occur across the four IPs in the 1Mbps bandwidth pool.
Equalizing is performed in the same fashion as across your entire network trunk; but in this
case it equalizes
within
the bandwidth pool. When the total bandwidth threshold for that
pool is reached, determined by the RATIO parameter, then any large connections (over
HOGMIN) associated with IP addresses within the bandwidth pool will be penalized.
Virtual equalizing was added for network topologies where bandwidth congestion is
occurring at nodes in the network, not necessarily at the WAN/LAN connection. For example,
this could be occurring in a wireless network where bandwidth congestion occurs at the
wireless hotspots or in the backhaul connections. Individual bandwidth pools can be defined
with the IPs of users at each hotspot and equalizing applied per hotspot.
One example of using Pools is to accommodate cases where bandwidth is advertised and
sold by Internet Providers as "you are one of n customers sharing x bandwidth". Another
example would be using bandwidth pools to set up equalizing at the subnet level. For
example, a university may split their network into faculty, administrators, and student
