Question:
Consider the token ring network in Figure below. Token is circulating between stations in the following sequence: A?B?C?13?E?F?A. Single token operation is implemented and 8 priority levels supported, with level 0 the highest priority while level 7 is the lowest The following data frames will be delivered by this network: Frame 1 from Node B, at priority level 4; Frame 2, from Node C. at priority level 2; Frame 3, from Node D, at priority level 1; Frame 4, from node F, at priority level 4. At the beginning, a free token with priority level 3 and reservation level 7 is released by node A. What is the sequence these four frames will be delivered? Justify your answer.
Consider the 40x40 circuit switch. a. Use space domain three-stage Clos switching network to implement this switch_ The designed switch should have the following features: non-blocking each input module has 5 input ports; and, each output module has 5 output ports. Draw the switch architecture. What is the complexity of the switch 4.1 architecture?) b. Use T-S-T hybrid switch to replace the Clos space domain switch designed in part a. Draw the hybrid switch architecture. c. Now consider the hybrid switch design in part b. Label the inputs or outputs from 0 to 39. Assume that a voice packet comes to input 1 and wants to be switched to output S. Please specify an internal path for this packet which has the minimum switching delay.
