The Precarious State of the WAN

In the age of the global cloud computing, reliance on wide area networks (WANs) has never been greater. The challenges facing CIOs is that while networks have become much more robust in the last decade, there is still a considerable difference between what an enterprise IT organization might experience in terms of application performance across a WAN in an emerging economy than what is generally seen in Europe or North America. To illustrate that point, Aryaka Networks, a provider of WAN optimization services that are delivered via the cloud, has issued a report that details the types of traffic are moving across WANs around the globe and the response times that customers are experiencing. The good news is that about two-thirds of the traffic is being generated by sites that have access to WAN links that provide 10 Mbps second or greater bandwidth. The bad news is that packet loss in places such as China and India can still be as high as 2.1 percent. Given the expense associated with deploying private leased lines, the odds are that the number of companies looking to accelerate cloud application performance across the WAN using standard Web protocols will be substantially higher within the next two years. The challenge? Finding the most cost-effective approach to achieving that goal.
