Suppose there is a router between two hosts and no other traffic than two packets to be sent from host A to host B$.$ Suppose that the red $($i$.$e$.$ thinner$)$ link is the bottleneck link. Also, suppose that the server sends the second packet T second after sending the first packet. Each packet is of L bits. What is min$($T$)$ to ensure no queuing in the router between these two hosts?
