Abstract
Microsoft and Cisco
®
have developed a joint solution that allows customers to deploy the Cisco
Content Switching Module (CSM) server load balancer in a Microsoft Terminal Server computing
environment. This white paper describes how to set up the Cisco CSM so that it is token aware,
providing a new level of intelligent load balancing that improves reliability and the end-user
experience.
Cisco CSM Overview
The Cisco CSM is a line card for the Cisco Catalyst
®
6500 Series Switches that enhances the
response of client traffic to endpoints, such as groups of servers, caches, firewalls, Secure
Sockets Layer (SSL) devices, and VPN termination devices. The Cisco CSM provides a high-
performance, cost-effective load-balancing solution for enterprise and Internet service provider
networks, allowing these organizations to provide customers, employees, and business partners
with the best possible online experience. The Cisco CSM meets the demands of high-speed
content delivery networks, tracking network sessions and server load conditions in real time and
directing client requests to the appropriate devices. Fault-tolerant Cisco CSM configurations
maintain full state information and provide the true transparent failover required for mission-critical
applications.
Microsoft Terminal Services Session Directory Overview
Microsoft Terminal Services Session Directory is a technology that lets users run Microsoft
Windows applications on a remote Windows Server 2003 computer. In a Microsoft Terminal
Server computing environment, all application execution and data processing occurs on the server.
In a load-balanced environment, a farm of terminal servers have incoming session connections
distributed in a balanced manner across the servers in the farm. The session directory keeps a list
of sessions indexed by user name and allows the user to reconnect to the terminal server where
the user's disconnected session resides and resume that session.
