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 an instant messaging gateway for external communities
Clients in a local IBM® Sametime® community can communicate with users in other communities through the Sametime Gateway.
Setting up load balancing for a cluster of Sametime® Proxy Servers
Install a load balancer in front of a cluster of IBM® Sametime® servers to distribute connections among the servers. The cluster should have at least two IBM WebSphere® SIP proxy servers deployed in front of it, so that the load balancer can direct connections to those proxy servers for forwarding to the individual Sametime servers in the cluster.

Setting up load balancing for a cluster of Sametime Proxy Servers

Install a load balancer in front of a cluster of IBM® Sametime® servers to distribute connections among the servers. The cluster should have at least two IBM WebSphere® SIP proxy servers deployed in front of it, so that the load balancer can direct connections to those proxy servers for forwarding to the individual Sametime servers in the cluster.

About this task

The WebSphere Network Deployment package available for use with Sametime includes IBM Load Balancer, which you can install as described in Installing IBM Load Balancer, and then configure for either MAC forwarding or IP routing. If you do not want to use IBM Load Balancer, you can install a third-party load balancer or IP sprayer; then configure the server for IP routing as explained in Deploying IP routing load balancers.
