Computer Networks

Consider the network shown below, with a sending server on the left, sending packets to two different client receivers on the right. The sender is sending packets to the receivers over separate TCP connection. The links have transmission rates of R1=200 Mbps (i.e., 200106 bits per second). Assume initially that R2=R3=25 Mbps. Suppose each packet is 1 Mbit (106 bits) in size. How long does it take a sender to transmit a packet into its link (i.e., the packet transmission delay at the sender)? 5msec 10msec 1msec 20msec 106msec
