About ten years ago, I had this lovely little silver device that fit in the palm of my hand and I remember thinking, "mobile devices can’t get much better than this." I could talk for hours and hours and send text messages when I couldn’t talk. Ok, so I couldn't check my email or browse the web, but who cared ten years ago? And best of all, I could charge up and go for days without the need to plug in. I was free. The untethered dream had been realized.

Video and P2P Rule! The traffic making up today’s networks is in a rapid state of flux. Just last week Sandvine, in their Spring 2011 Global Phenomena Report, noted that real-time entertainment continues to increase, and within North America represents almost 50% of peak fixed access traffic (much of this of course is due to Netflix). P2P traffic also continues to carve out a sizeable piece of the pie at around 20%. The rest is a mix of voice, business apps, games, Facebook and chat. Wha...

There’s been a lot of debate recently about the impact of video apps on the network. According to Nielsen, Netflix alone now accounts for 20% of downstream traffic during peak times in the United States. In a previous blog Kowsik explained the behind-the-scenes interactions that are happening unbeknownst to you when you watch a Netflix movie.
