Consider a LAN consisting of a 200Mb/s ring cable. Data travels over the cable at the speed of light (2.3x 108 m/s). On the ring, n repeaters are intercon- nected in equal distance to form a closed loop, and each host is connected to one repeater. When a host transmits a frame, its associated repeater forwards the frame to the ring. The ring is unidirectional, so a frame can flow in one direc tion. During the circulation of the frame in the ring, the destination host cppies the frame into its buffer. Once copied by the destination, the frame continues its circulation until the sender receives it and removes it from the system. To avoid collision, only one host can transmit at a given time. (a) Ignoring delay at repeaters, find the circumference of the ring to exactl contain a 1,400-byte frame. (b) Find the circumference of the ring to exactly contain a 1,400-byte frame if n is supposed to be 12 and each repeater and its host combined introduce a 5-bit delay
