Q.3 (2Spts) Show all your work. 5 stations are transmitting on some shared medium. The MAC is an experimental CSMA/CD network. The NIC (Network Interface Card) that implements the link layer has the following hardware configuration Upper LayerThe shared medium has a maximum round trip propagation delay of 2t Imsec. The data transmission rate of the shared medium is 10 Kbps. The frame sizes are exponentially distributed with an average size of 900 bits. A 1 frames/sec NIC PrameThe measurements on the channel show that: Queue | The channel has collisions 30% of the time and is idle 60% of the time. Each station generates Poisson distributed frames with a rate of 1 frames/sec. Assume that channel access time preserves the exponential service times. CSMA/CD a) What is the average contention time for any frame on this channel? b) What is the average frame time for a given station? What is your assumption? What is the average time a frame from a given station spends from th last bit is transmitted? 0) e time it is generated until its Q.3 (2Spts) Show all your work. 5 stations are transmitting on some shared medium.
