“…60% of the videos' segments are stored in each cache server randomly in most scenarios (only in one scenario, we store 30% to 60% videos segments on cache servers). Moreover, each client requests one video where video 1 is streamed to clients (1,11,21,31,41,51,61,71,81,91), video 2 is streamed to clients (2,12,22,32,42,52,62,72,82,92), and so on. The time slot duration is adjusted to 32 milliseconds in all experiments.…”
