Compare the performance of token bus (IEEE 802.4) and token ring (IEEE 802.5). Assume a network has 1,000 stations and the propagation delay between two adjacent stations is 10^-6 second and the propagation delay through the whole network is 10^3 second. The packet transmission time is 10^-4 second. a. Assuming no transmission errors, how many packets that can be transmitted in one second in token bus? b. How about that of token ring? c. Is there a condition that token bus can outperform token ring? Why? Compare the performance of token bus (IEEE 802.4) and token ring (IEEE 802.5).
