I reviewed this paper as part of my Computer Communications course at USC. Introduction YouTube traffic is bursty. These bursts trigger packet losses and stress router queues, causing TCP congestion-control algorithm to kick in. The paper provides an implementation called Trickle, a server side mechanism which uses TCP to rate limit YouTube video streaming. Trickle paces the video stream by placing an upper bound on TCP’s congestion window. YouTube follows the concept of just-in-time delivery i.

I use foursquare a lot, I mean a lot! So, a few months back I decided to write a foursquare application which would make sense of my foursquare check-in’s.

San Diego Day Trip

I have not been able to blog for a while now as I have been very busy this spring semester at USC. During the spring break at USC me along with few friends of mine made a day trip to San Diego. It was all decided in the last moment, and it was an amazing success. We booked a rental car from enterprise and the renting price was dirt cheap. We had a rough estimate of what places we would be visiting in San Diego.
