Question Two a) Explain the ARP protocol to a friend. In that explanation, mention what layer it operates at and the kind of service it provides to the layer above it. b) Having ARP table entries time out after 10 to 15 minutes is an attempt at a reasonable compromise.

3.4-8 Channel utilization with pipelining. Suppose a packet is 10K bits long, the channel transmission rate connecting a sender and receiver is 10 Mbps, and the round-trip propagation delay is 10 ms. What is the channel utilization of a pipelined protocol with an arbitrarily high level of pipelining for this channel?
1)Does RTS/CTS message ensure that data frames from difffferent nodes never collide? 2)Suppose that the wireless links are vey noisy and difffferent nodes communicate with each other via TCP segments, so that TCP segments may be lost/dropped due to bit errors. Discuss whether TCP could be a good protocol used in this scenario.
Consider the datagrams of each layer in the TCP/IP model, e.g., Frame at the Link Layer, Packet at the Internet Layer. Explain the functioning of the following protocols based on their datagram header fields only. Note: You do not need to describe the header field but based on the header field, explain how the protocol works, e.g., Acknowledgement field in a TCP Header is responsible for providing reliable data transfer and in case of data loss or ACK not received, segment is re-sent. You do not need to consider every field of the headers but wherever there are more than 4 fields, then based on 5 fields, describe its functioning, if less than or equal to 4 fields then consider all the fields.

Consider a TCP connection with the following parameters: a) Initial ssthreshold = 4 segmentsb) Round Trip Time (RTT) = 10 millisecondsc) Timeout period = 40 millisecondsd) Segment size = 3900 bytesThe TCP connection was used to transfer 17 data segments. While sendingthe segments, data segment 7 and data segment 15 were lost the first timethey were sent (but arrived at the receiver properly when retransmitted).There were no other segment losses apart from the aforementioned. Assumethat data segments received out-of-order are buffered at the receiver. Whatis the average throughput obtained in sending all the data segments (inbytes/sec)? Draw a diagram to show the communication process in detail.

The Transport Control Protocol (TCP) is a transport layer protocol that provides full duplex, connection-oriented, and reliable delivery services. When we say connection-oriented, reliable delivery, and full duplex, what exactly do we mean? What are connection-oriented, dependable delivery, and full duplex mean?
a) What method can be used by two computers to ensure that packets are not dropped because too much data is being sent too quickly? At what layer in the OSI model would this be implemented? Describe how TCP implements this feature. b) Explain the difference between how a network switch will decide to forward a frame and how a router will decide to forward a packet. Give details of the information held by each device to enable these forwarding/routing decisions to be made.
TCP (Transport Control Protocol) is a transport layer protocol that offers full duplex, connection-oriented, and trustworthy delivery services at the transport layer. When we talk about full duplex, reliable transmission, and connection-oriented communication, what do we mean? So, what exactly do we mean when we talk about connections, resiliency in delivery, and full duplex?
3.5-1a. TCP RTT estimation and timeout value. Suppose that TCP's current estimated values for the round trip time (estimated RTT) and deviation in the RTT (DevRTT) are 300 msec and 13 msec, respectively. Suppose that the next two measured RTTS are 330 msec and 240 msec respectively. We want to calculate TCP's RTT estimate, and the value of TCP's timeout interval. Note that given a new measured RTT, you should first compute devRTT, then estimated RTT (the textbook incorrectly reverses those computations), and then (lastly) the timeout interval. Use the values of a = 0.125, B = 0.25. Following the newly measured RTT of 330 msec, what is the new value for devRTT in msec? [Note: round your answer to the nearest msec - enter an integer value, do not include any decimal places/point or any leading zeros, but keep your full resolution value of devRTT handy and use it in any later calculations you perform using devRTT.
