CITM-600 Assignment-1 (5%) Characterizing Network Traffic There are 1000 stations in a network. Each of the stations transmit 5 frames/second and size of one frame is 2000-bits. As, we know in addition to application data, different protocols add differently sized header with application data before they are sent through media. The additional data from protocols are called overhead. For example, TCP/IP add 20 bytes overhead, UDP adds 8 bytes overhead and Ethernet II adds 38 bytes overhead, with each data...
