can be used to display a list of currently active users in each pipe.
10.1.9. A Summary of Traffic Shaping
NetDefendOS traffic shaping provides a sophisticated set of mechanisms for controlling and
prioritizing network packets. The following points summarize its use:
•
Select the traffic to manage through
Pipe Rules
.
•
Pipe Rules send traffic through
Pipes
.
•
A pipe can have a limit which is the maximum amount of traffic allowed.
•
A pipe can only know when it is
full
if a total limit for the pipe is specified.
•
A single pipe should handle traffic in only one direction (although 2 way pipes are allowed).
•
Pipes can be chained so that one pipe's traffic feeds into another pipe.
•
Specific traffic types can be given a
priority
in a pipe.
•
Priorities can be given a maximum limit which is also a guarantee. Traffic that exceeds this
will be sent at the minimum precedence which is also called the
Best Effort
precedence.
•
At the best effort precedence all packets are treated on a "first come, first forwarded" basis.
•
Within a pipe, traffic can also be separated on a
Group
basis. For example, by source IP
address. Each user in a group (for example, each source IP address) can be given a maximum
limit and precedences within a group can be given a limit/guarantee.
•
A pipe limit need not be specified if group members have a maximum limit.
•
Dynamic Balancing
can be used to specify that all users in a group get a fair and equal
amount of bandwidth.
10.1.10. More Pipe Examples
This section looks at some more scenarios and how traffic shaping can be used to solve particular
problems.
A Basic Scenario
The first scenario will examine the configuration shown in the image below, in which incoming
and outgoing traffic is to be limited to 1 megabit per second.
