ABSTRACT
The article discusses the problem of response time for remote users faced by network managers. The traditional remedy of adding a bandwidth works in many cases. Doubling the speed of the line does reduce the amount of time it takes to transmit the packets and is generally the best solution when the link is running at a high utilization. If the users are experiencing slow response time and the link utilization is low -- under 40 percent -- then adding more bandwidth will only marginally improve their response time. If there are only a few users at the remote site, throwing bandwidth at the problem is also unlikely to improve the situation because the real problem is the TCP connection limiting the amount of data that can be sent. Adding bandwidth doesn't address this problem, it just makes the link utilization percentage go down. Plus, throwing bandwidth at the problem every time someone complains is expensive. Technology, in the form of application accelerators, can help improve response time even when there is no crisis.
