Sandvine, a star player in this year's Comcast throttling controversy, has released a new study claiming that 61% of all upstream traffic is P2P. According to the network gear maker, P2P is responsible for more than 22 per cent of downstream bandwidth consumption. Sandvine wants to sell traffic management gear and has a vested interest in portraying P2P traffic as an uncontrollable nuisance, though some data suggests P2P's dominance of the pipe may be dropping; replaced by audio/video. "Effective network traffic optimization techniques use sophisticated policies that balance network capacity, application requirements and subscriber quality of experience in real-time," Sandvine pitches. Actually upgrading your infrastructure helps too.
