Consider, on the other hand, a video captutring a scene where the camera tracks a fast moving action visual. Compare the compression for these two videos - the amount of likely compression ratio, and the relative no. of I/P/B frames. Q4) What is the purpose of maintaining virtual time in the weighted fair queuing and start-time fair queuing scheduling algorithms? Q5) Despite that GFS scales well, it could be argued that the master is still a potential bottleneck. What would be a reasonable alternative to replace it?...
