There are 800 stations in a network. Each station transmits 500 frames/second, and the size of one frame is 3200 bits. As we know, in addition to the application data, different protocols add differently sized headers with the application data before they are sent through the network media. The additional data from protocols are called overhead. For example, TCP adds 20 Bytes overhead, UDP adds 8 Bytes overhead, and Ethernet II adds 18 Bytes overhead with each frame. Also, routing protocols add overhead when routing information between routers in the network is exchanged. For example: Open Shortest Path First (OSPF) routing protocols send the Hello packets every 10 seconds. The size of this Hello packet is 2 Bytes. Enhanced Interior Gateway Routing Protocols (IGRP) send the Hello packets every 5 seconds, and Routing Information Protocol (RIP) sends the entire Routing table every 30 seconds. Assume the routing table size for each of the routers is approximately 200 KB (KiloBytes), there are fifteen routers in the network, and the routers use the RIP protocol. Traffic load calculation should take these protocol overheads into account. Now, based on the given information above, please prepare the answer to the following questions: 1. What is the offered load in the network in Mbps? 2. What is the Routers' overhead in the network in Mbps? 3. If all the stations use the TCP protocol, what is the stations' overhead in Mbps? 4. If all the stations use the UDP protocol, what is the stations' overhead in Mbps? 5. What is the stations' overhead in Mbps for the Ethernet II protocol? 6. What is the total overhead (i.e., including routers' overhead) in Mbps when only (TCP+ Ethernet II) is used? 7. What is the total overhead (i.e., including routers' overhead) in Mbps when only (UDP + Ethernet II) is used?8. What minimum bandwidth in Mbps should the network support to accommodate application data and overhead when using (TCP + Ethernet II)? 9. What minimum bandwidth in Mbps should the network support to accommodate application data and overhead when using (UDP + Ethernet II)?
