Posts about Bandwidth Demand

Network requirements across the distributed enterprise are becoming more complex. From server-to-server mesh fabrics to long-haul virtual networks, applications are demanding more speed, more flexibility and more reliability. At the same time, enterprises, cloud providers and even metro carriers are tasked with driving down the cost of network expansion and operations, which is accomplished largely by streamlining infrastructure and making more use of available bandwidth ...

In the last few years, Data Center Operators and Internet Content Providers (ICPs) have grown from being just footnotes on analysts' charts to dominating transport bandwidth consumption. A pervasive question in the press this year has been how much bandwidth do the new kings of consumption really need? One prognosticator will claim they need as much as they can get, and would buy a Petabit if made available today, while another industry sage proffers a single Terabit will suffice for the foreseeable future. So who's right? It turns out, both. To illustrate the point, let's look at two ICPs in the exact same line of business, similar in size, global reach, and number of subscribers. Both have hundreds of thousands of servers running in leaf and spine configurations. Computing clusters are formed by groupings of these servers and switches between them. These clusters used to be ...

Bandwidth demand growing exponentially for years while revenue per bit is dropping causes service provider margins to diminish. When combining this trend with unpredictable traffic patterns and a peak-to-average traffic ratio that is increasing quickly due to the adoption of cloud computing and social media applications, technology that will help service providers to streamline their operations and reduce total cost of ownership is needed badly.
