example: ▪ 1 Gb/s link ▪ each user: N users ▪ circuit-switching: 10 users ▪packet switching: with 35 users, probability > 10 active at same time is less than .0004 * • 100 Mb/s when "active" • active 10% of time Q: how many users can use this network under circuit-switching and packet switching? 1 Gbps link Q: how did we get value 0.0004? A: HW problem
