To put things in perspective about the unabated growth of video traffic, Shetty said it is appropriate to start thinking in terms of the zettabyte, which is the same as 1,000 exabytes. Shetty has become a walking encyclopedia on the zettabyte, noting that the growth in all IP traffic globally will be nearly 50% between now and 2012, based on a Cisco forecast that noted the enormous increases in video traffic, as well as social networking and business applications.
To meet the additional annual bandwidth demand of that forecast, Shetty said Cisco has estimated the world's IP networks will need to handle 522 exabytes more each year, which is equivalent to downloading 125 billion DVD movies each month.
Cisco named Softbank , a network provider in Tokyo as expressing an interest in the ASR 9000, especially to incorporate 4G wireless and video traffic in its more conventional networks.
