So you’ve read about our IP traffic study in some past posts — If you’ve been wondering whether traffic growth is really occurring and what’s the impact of this growth to the networks, I can firmly attest that absolutely it is. Every major service provider I have interacted with over the past 6 months has talked about how their traffic is growing faster than before -- but not necessarily at the same rate for all. What’s behind this traffic growth? Personally, all you have to do is look inside any of our homes to see the drivers. Let’s take mine as an example. My 15 year old son has stopped watching television and lives his academic and social life in the virtual world through a laptop or through a game console. My 12 year old daughter is also spending more time online with her friends but with slightly different interests. What’s most intriguing is that my 8 year old son is watching videos online continually. Even my wife prefers to occasionally catch snipets of her favorite shows from the www than on live television. As soon as a provider can deliver faster bandwidth to my house, they can count on me as a customer. Where am I going with this? I know that I am not an exception but more of the standard of homes with kids. It is clear that video is the big driver of this growth and will continue to be as we increase the number of creators of content and consumers of content and ways that it can be consumed.Early in April Cisco announced that sales of Cisco CRS-1 have doubled in less than 9 month from 900 to 1800 units. This is clearly a sign that service providers around the world are conducting expansions of their networks but want to be assured that as traffic continues to grow they will be able to scale their networks. The multi-chassis capability of CRS-1 allows SPs to scale their systems where needed while the 16, 8 and 4 slot single shelf systems allow the SPs to grow the footprint of the core network to accommodate the rapid increase in the number of subscribers and the bandwidth per subscriber.The question we need to ask ourselves are -- will this insatiable demand for bandwidth continue at the rate of the forecasts? Or will it be even higher?
