A communication link has a bit rate of 10 Gbps and a length of 20 km. Propagation velocity is 2.5 × 108 m/s and ACK frames are piggybacked on information frames going in the reverse direction, one ACK for every received frame. Information frames are 9000 bytes long. The frame header is 100 bytes. (a) What is the minimum window size that maximizes the effective bit rate? (b) What is the information effective bit rate if the window size is 16 frames?

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.
