Bandwidth Control

TANDBERG VIDEO COMMUNICATION SERVER ADMINISTRATOR GUIDE

Applying Pipes to Links

Pipes are used to restrict the bandwidth of a link. When a pipe is applied to a link, it will restrict the bandwidth of calls made between the two nodes of the link - the restrictions will 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 wish to model your network.

One Pipe, One Link

Applying a single pipe to a single link is useful when you wish to apply specific limits to calls between a subzone and another specific subzone or zone.

One Pipe, Two or More Links

Each pipe may be applied to multiple links. This is used to model the situation where one site communicates with several other sites over the same broadband connection to the Internet. A pipe should be configured to represent the broadband connection, and then applied to all the links. This will allow you to configure the bandwidth options for calls in and out of that site.

Default Links

About Default Links

If a subzone has no links configured, then endpoints within the subzone will only be able to call other endpoints within the same subzone. For this reason, the VCS comes shipped with a set of pre-configured links and will also automatically create new links each time you create a new subzone.

Pre-Configured Links

The VCS is shipped with the Default Subzone, Traversal Subzone and Default Zone already created, and with links pre-configured between the three. You may delete or amend these default links if you need to model restrictions of your network.

If any of these links have been deleted, they may all be automatically restored via:

•xCommand DefaultLinksAdd

To restore these links via the web interface, you must do so manually. See Creating Links for instructions on how to do this.

Two Pipes, One Link

Each link may have up to two pipes associated with it. This is used to model the situation where the two nodes of a link are not directly connected, for example two sites that each have their own broadband connection to the Internet. Each connection should have its own pipe, meaning that a link between the two nodes should be subject to the bandwidth restrictions of both pipes.

Automatically Created Links

Whenever a new subzone or zone is created, links are automatically created as follows:

New zone/subzone type	Default links are created to...
Subzone	Default Subzone and Traversal Subzone
Neighbor zone	Default Subzone and Traversal Subzone
DNS Zone	Default Subzone and Traversal Subzone
ENUM Zone	Default Subzone and Traversal Subzone
Traversal Client Zone	Traversal Subzone
Traversal Server Zone	Traversal Subzone

You can edit any of these default links in the same way you would edit manually configured links. See Editing Links for more information.

!Calls will fail if links are not configured correctly.
