Exercise (3): Use (1) Timing Diagram Method (2) Formulas Method Consider three intermediate nodes between A and B users, hop interval for each packet is 2sec. Determine 1- Transmission time for sending 5 packets using Packet-switching. 2- If the message consists of 10 packets, what is transmission time of message-switching. 3- Which transmission is the best? Note: Please read carefully the example in lecture. In example: 1 min= 60sec and each 1 min will be divided into 60 packets then each packet need 1sec (i,e. hop time) to be transmitted from node-to-node.
