Example 4: Two sites with two classes of users

Example 4 combines two different sites with two different classes of users within a network managed by IBM® Sametime® Bandwidth Manager.

In this example, call policies differ based on the classes of users involved in the call and the site where the users are located.
Scenario 1 has the following business objectives:
  • Calls within the US and within Europe are allowed to use 384 kbps for video
  • Calls between the US and Europe are limited to 256 kbps for video
  • All VIP-to-VIP video calls use 384 kbps
  • All VIPs continue to place calls as normal when peak utilization bandwidth conditions exist
  • All other users will use audio-only when peak utilization bandwidth conditions exist
The required policies for this example are:
Table 1. Policies for Scenario 1Scenario 1 policies that have mixed user class and site location conditions
Order User1 Site1 User2 Site2 Normal Call Rate Peak Utilization Call Rate
1 VIP Any VIP Any Video call, 384 kbps Video call, 384 kbps
2 Any EMEA Any US Video call, 256 kbps Audio-only call, 16 kbps
3 Any Any Any Any Video call, 384 kbps Audio-only call, 16 kbps
Scenario 2 has the following business objectives:
  • All video calls within Europe or within the US that involve VIPs are allowed to run at 384 kbps
  • All other video calls within those regions, US and Europe, are limited to 256 kbps
  • Between the regions, VIP-to-VIP video calls are allowed to run at 256 kbps
  • Between regions, all other video calls are limited to 192 kbps
  • All VIPs continue to place calls as normal when peak utilization bandwidth conditions exist
  • All other users will use audio-only when peak utilization bandwidth conditions exist
The required policies for this example are:
Table 2. Policies for Scenario 2Scenario 2 policies that have mixed user class and site location conditions
Order User1 Site1 User2 Site2 Normal Call Rate Peak Utilization Call Rate
1 VIP US VIP EMEA Video call, 256 kbps Video call, 256 kbps
2 VIP Any Any Any Video call, 384 kbps Video call, 384 kbps
3 Any US Any EMEA Video call, 192 kbps Audio-only call, 16 kbps
4 Any Any Any Any Video call, 256 kbps Audio-only call, 16 kbps
