Q) Consider a single TCP connection using a 10 Gbps link which does not buffer any data. Assume the TCP sender has a huge file to send to the receiver and the receiver’s receive buffer is much larger than the congestion window. We make the following simplifying assumptions: → Each TCP segment size is 1500 bytes → The RTT of the connection is 100 ms → The TCP connection is always in congestion avoidance (ignore slow start) Calculate the loss rate of L using the given image as a formula to achieve 10 Gbps throughput, please specify all the calculations in detail.

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.
