NetEqualizer allows up to 60 thousand (60,000) unique active Hard Limits.
You can set a Subnet Hard Limit, which applies to an entire set of IPs, such as a /24 or /16,
and also set an
override hard limit for an individual IP in that range.
It is important that the
Subnet Hard Limit base address does NOT match the override individual IP.
For example, this is allowed:
Subnet Hard Limit = 10.1.1.0 /24
Override Hard Limit = 10.1.1.143 /32
This is NOT allowed:
Subnet Hard Limit = 10.1.1.143 /24
Override Hard Limit = 10.1.1.143 /32
When setting up Subnet Hard Limits, we recommend using .0 for the base address. This
means that you can have override Hard Limits for any IP except 10.1.1.0 (using our
example). This should not be a problem, as DHCP does not usually assign out .0 in
common practice.
Note: If you plan to set up a large number of subnet-ranged Hard Limits (>=32 subnet
ranges), you will need to set several tuning parameters. Please see
Appendix #5
for
detailed instructions.
Adding Bursting to Hard Limits
(
back
)
In addition to setting a Hard Limit by IP address, as of
software update 4.7
, we have
enabled "bursting" above the Hard Limit. Prior to the bursting feature, the top speed
allowed for each user was fixed at the set Hard Limit.
Now with bursting, a user can be allowed a burst of bandwidth for up to 10 seconds at two,
three, four, or any multiple of their base Hard Limit. For example, if a user has an incoming
base Hard Limit of 2 megabits a second, and a burst factor of 4, then their inbound
connection will be allowed to burst all the way up to 8 megabits for 10 seconds (2Mbps
HARD LIMIT x 4 BURST FACTOR = 8Mbps inbound BURST LIMIT), at which time it will revert
back to the original 2 megabits per second. If the outgoing base Hard Limit was set to 1
megabit per second, with the same burst factor, the outbound BURST LIMIT would be
4Mbps.
This type of burst will be noticed when loading large Web pages loaded with graphics. From
a user's perspective, they will essentially fly up in the browser at warp speed.
In order to make bursting a “special” feature, it obviously can’t be on all the time. For this
reason, by default the NetEqualizer will force a user to wait 80 seconds before they can
burst again.
To set up Bursting on an IP Address:
From the Setup and Configuration Menu,
Click on ->
Manage Traffic Limits
->
[
Configure Hard Limits by IP Address
].
The last field in the command specifies the
burst factor
. Leave this field set to 1
for no bursting, or set to a multiple greater than 1 for bursting. BURST FACTOR is
multiplied times the incoming and outgoing HARD LIMITs to arrive at the BURST LIMITs
