Optimizing Bandwidth: Why Size Doesn’t Always Matter

Network managers have to balance the need for increased speed of response and the best possible end user performance, and the need to reduce costs.

Traffic on the network expands to fill the available bandwidth, resulting in degraded performance across the most congested links. Network managers have to be able to show that a link is experiencing congestion for a significant amount of time due to legitimate business usage before they can add additional capacity. But approaches such as peak or average utilization and traffic totals provide limited insight into and understanding of network congestion.

To optimize the use of existing capacity and make the business case for more bandwidth, network managers need to ask themselves a number of questions. In this white paper, a new approach to getting needed information about network congestion is discussed. Principles to consider for effective capacity planning are discussed, as well as the limitations to traditional approaches to managing network capacity, and a solution called burst utilization is given, to measure performance and save network managers time.

A burst-style view shows the links spending the most amount of time in a congested state and the time in that state. Using this information, the network manager can explore why the link is busy and whether additional bandwidth is needed, and identify any links where capacity could be reduced. By using existing bandwidth more effectively, they may be able to improve the end user experience.  Read More
