CLO1.1 FILL IN THE BLANK. * DO NOT USE SHORTCUTS e.g., app or net 1. IP layer is the layer 2. layer is layer 1. 3. HTTP is an layer protocol. 4. Ethernet is a layer protocol. 5. layer is responsible for moving bits across wired and wireless links. 6. is responsible for routing and moving the packets from source host to destination host. 7. is the process of taking upper layer data and adding current layer header. 8. Transport layer data unit is commonly known as 9. layer is responsible for data transfer between adjacent network devices across a single link. 10. layer is responsible for the communication between processes running on the interacting hosts. 11. A router can process up to the layer while a host processes up to the layer 12. A layer protocol encapsulates network layer datagram. 13. A data transfer between two hosts typically starts from the layer. A) What is the maximum achievable end-end throughput for each client-to-server pair, assuming that the middle link is fairly shared among connections (divides its transmission rate equally) and all servers are trying to send at their maximum rate? [4] B) Which router will be building up waiting queues? Why? [6] CLO2.1 A packet of 1.6 kbit length propagates over a 1,500km link, with propagation speed 3108m/s, and transmission rate 10 Mbps. (example1 \& Answer the following questions and show your steps. A) Calculate the propagation delay in millisecond (ms). [5] B) Calculate the transmission delay in millisecond (ms). [5] C) What is the total delay (ignoring other delay components)? [5] D) Repeat c) if there were three links separated by two routers and all the links are identical and processing time in each router is 200s [10]
