Question

P9. Consider the discussion in Section 1.3 of packet switching versus circuit switching in which an example is provided with a 1 Mbps link. Users are generating data at a rate of 100 kbps when busy, but are busy generating data only with probability p = 0.1. Suppose that the 1 Mbps link is replaced by a 1Gbps link. (a) What is N, the maximum number of users that can be supported simultaneously under circuit switching?

Answer 1

Answer:

  10,000

Step-by-step explanation:

The link capacity is 10^9 bps; the link usage is 10^5 bps per user, so the number of users that can be supported is ...

  (10^9 bps)/(10^5 bps/user) = 10^4 users
