Configuring Pipes
Pipes are used to control the amount of bandwidth used on calls between specific subzones and zones. The limits
can be applied to the total concurrent bandwidth used at any one time, or to the bandwidth used by any individual
call.
can be applied to the total concurrent bandwidth used at any one time, or to the bandwidth used by any individual
call.
To apply these limits, you must first create a pipe and configure it with the required bandwidth limitations. Then when
configuring
configuring
you assign the pipe to one or more links. Calls using the link will then have the pipe’s bandwidth

The Pipes page (Configuration > Bandwidth > Pipes) lists all the pipes that have been configured on the Expressway
and allows you to create, edit and delete pipes.

for more information about how the
bandwidth limits are set and managed.
Applying Pipes to Links
Pipes are used to restrict the bandwidth of a link. When a pipe is applied to a link, it restricts the bandwidth of calls
made between the two nodes of the link - the restrictions apply to calls in either direction. Normally a single pipe
would be applied to a single link. However, one or more pipes may be applied to one or more links, depending on how
you want to model your network.
