Datacenter Design: Optimizing Networks for Evolving Traffic

Data center network design architecture is changing to reflect growing IT trends in distributed applications and virtual computing. New computing models require a flatter network that is flexible enough to handle unpredictable traffic patterns. Find out what that means for your company in this interview with Cindy Borovick, Vice President of IDC’s Enterprise Communications and Datacenter Networks programs.

Troubleshooting Remote Site Networks—Best Practices

Management and remote site employees expect the same level of network service as the headquarters site. However, when IT staff are faced with limited resources to support remote site networks, often the applications, services and performance at those sites are not as robust as the headquarters site. See how to deliver a high level of network service at remote sites using best practices outlined in this white paper. Read More

Green Server Design: Beyond Operational Energy to Sustainability

  • Published:
“Green” server and datacenter design requires a focus on environmental sustainability. Prior studies have focused on operational energy consumption as a proxy for sustainability, but this metric only captures part of the environmental impact. Understanding the total impact requires examining the entire lifecycle of the system, beyond operational energy, to also include material use and manufacturing. See how one methodology can do that. Read More

NGN Control Plane Overload and its Management

Given the types of overload scenarios encountered within traditional networks, similar traffic principles requiring overload management will be required within (NGNs). What, then, are the characteristics of overload protection within real-time communications servers? And what types of overload management methods are available for optimizing server performance? Read More

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
