Deploying
IBM® Sametime® consists of a variety of servers and clients, and can be deployed to suit many different environments. The deployment instructions are organized by feature set, beginning with the minimum components that are necessary to support instant messaging, and then expanding the deployment to include features such as audio and video support, and conferencing.
Deploying audio and video
Audio and video features are provided primarily by the IBM® Sametime® Media Manager, which supports point-to-point and multipoint calls. The Sametime Media Manager uses standard audio and video codecs so that it works with products from other audio and video vendors.
Installing Sametime® Bandwidth Manager
The IBM® Sametime® Bandwidth Manager is an optional component that lets you configure bandwidth usage settings for your Sametime deployment.
Configuring Sametime® Bandwidth Manager
Configure the bandwidth management modules to control bandwidth usage within a network managed by IBM® Sametime® Bandwidth Manager, defining sites, links between them, call rates that control bandwidth utilization, and policies that apply the rates to various classes of user.
Configuring call rate policies
In an IBM® Sametime® Bandwidth Manager deployment, you can define call rates to be used during periods of normal utilization, and call rates to be used during periods of peak utilization. Combine these call rates with different classes of users and different locations to create call rate policies.
Call rate policy examples
To understand how call rate policy works in a network managed by IBM® Sametime Bandwidth Manager, review the examples in this section.
Example 2: Two sites with one class of user
Example 2 shows a scenario where different call rates are applied for calls between certain sites, where bandwidth is limited within a network managed by IBM® Sametime® Bandwidth Manager.

Example 2: Two sites with one class of user

Example 2 shows a scenario where different call rates are applied for calls between certain sites, where bandwidth is limited within a network managed by IBM® Sametime® Bandwidth Manager.

A second scenario considers two different sites or groups of sites. In this scenario, all users are treated uniformly, but different sites are considered to enforce different call rates within the sites or between the sites.

For example, consider the example where administrators allow

384 kbps normal call rate for video calls within North America and within Europe
128 kbps normal call rate for video calls across the Atlantic
For all calls, force 16 kbps audio-only calls when peak utilization bandwidth conditions exist

The required policies for the Example 2 scenario are shown in Table 1. different call rates are applied for calls between certain sites, where bandwidth is limited within a network managed by IBM Sametime Bandwidth Manager.

Table 1. Policies Applied When Bandwidth is LimitedPolicies that specify different call rates between certain sites
Order	User1	Site1	User2	Site2	Normal Call Rate	Peak Utilization Call Rate
1	Any	NA	Any	NA	Video call, 384 kbps	Audio-only call, 16 kbps
2	Any	EMEA	Any	EMEA	Video call, 384 kbps	Audio-only call, 16 kbps
3	Any	EMEA	Any	NA	Video call, 128 kbps	Audio-only call, 16 kbps
4	Any	Any	Any	Any	Video call, 384 kbps	Audio-only call, 16 kbps
