Consider Setting Bandwidth Priority
NetEqualizer's default equalizing rules, which are set to "on" by default, are able to handle
congestion-related traffic flow problems for most organizations. Most types of traffic that
organizations want to prioritize are
prioritized by default
just by using the Equalizing Rules.
However, some organizations need to setup
Bandwidth Priority Rules
for specific traffic
types. There are two types of priority that you can set up on the NetEqualizer: 1) traffic
with priority over equalizing, and traffic hidden from equalizing.
We will discuss these in detail below:
1.
Priority Traffic
- Predefined IPs or subnets with
priority over equalizing.
2.
Masking Off Traffic
- Traffic hidden from equalizing.
Priority Traffic
gives known IP addresses and their associated streams preferential
treatment. Bandwidth Priority Rules are most often used for streaming-video traffic. For
example, if a business is streaming training videos into corporate offices, a "Priority Traffic"
Rule would need to be set up to prioritize the IP address of the server or site hosting the
training videos.
Masked Traffic
is "invisible" to the NetEqualizer. Typically this is used to
exclude local
traffic
(i.e. a computer talking to a server on your network) crossing the NetEqualizer link
from being considered for any shaping decisions.
Defining Priority Traffic
(
back
)
How does NetEqualizer grant priority for IP addresses? NetEqualizer recognizes
two classes of traffic:
1.
Priority Traffic
2.
Data Traffic
When
Priority Traffic
is detected, the bandwidth allocation for rest of the Data Traffic is
reduced. When NetEqualizer identifies a priority IP address, it typically performs the
following process:
1.
A priority IP address becomes active
2.
NetEqualizer dynamically reduces the data congestion ratio (
RATIO parameter
) by
a few percent
3.
This action (b) forces the PENALTY mechanism to kick in a bit sooner for non-
priority streams, thus reserving space for your priority traffic
4.
Priority traffic is given immunity to flow control. These streams will not be
slowed by PENALTIES applied in
Equalizing
. However, any Bandwidth Limiting
Rules, such as
Hard Limits
, will remain in effect.
Priority Traffic is assured bandwidth, up to the size of your network pipe. When you set up
Priority Traffic, all your other traffic is dynamically pushed into a smaller bandwidth window.
Note that if you set too much priority traffic, you will push all your remaining traffic into a
