Types Of Protocols

A network protocol is a collection of rules that governs the exchange of data between devices connected to the same network. In other words, network protocols are rules that specify how devices communicate or transfer data over a network. The sender and receiver systems must obey the standards to facilitate communication between them.

In the generic SR protocol, the sender transmits a message as soon as it is available (if it is in the window) without waiting for an acknowledgment. Suppose now that we want an SR protocol that sends messages two at a time. That is, the sender will send a pair of messages and will send the next pair of messages only when it knows that both messages in the first pair have been received correctly.Supposethat the channel may lose messages but will not corrupt or reorder messages. i) Outline an error-control protocol for the unidirectional rdt of messages. ii) Give an FSM description of the sender and receiver. iii) Describe the format of the packets sent between sender and receiver and vice versa. iv) If you use any procedure calls other than those in SR protocol (for example, udt_send(), start_timer(), rdt_rcv(), and so on),clearly state their actions. v) Give an example (a timeline trace of sender and receiver) showing how your protocol recovers from a lost packet
Two neighboring nodes ( A and B ) use a sliding - window protocol with a 3 - bit sequence number . A go - back - N is used with a window size of 5 . Assuming A is transmitting and B is receiving , show the window positions for the following succession of events : a . ) Before A sends any frames b . ) After A sends frames 0 , 1 , 2 , 3 , 4 and B acknowledges them . c . ) After A sends frames 5 , 6 , and 7 and B acknowledges them and the ACK is received by A.
In the discussion of ARQ protocol in Section 3.3.3, a scenario was outlined that resulted in the receiver accepting two copies of the same frame due to a loss of acknowledgement frame. Is it possible that a receiver may accept multiple copies of the same frame when none of the frames (message or acknowledgement) are lost?
For NAT Network Address Translation Scenario: Jenny Bello is a small business owner selling and making customized computer peripherals. She has been finding it difficult to track her sales and inventories, however recently after an expert's advice, she adopted a Point of Sale (PoS) server. So, she can now track her sales and inventories at the store. However, she ran into another issue, the server can only be accessed within the store, because it has been assigned a private IPv4 address, it is not publicly accessible via the Internet. a) Why is not having the PoS server accessible over the Internet a problem for the business? b) What caused this problem? c) Propose a solution for the problem and explain how the solution works.

In modern packet-switched networks, including the Internet, the source host segments long, application-layer messages (for example, an image or a music file) into smaller packets and sends the packets into the network. The receiver then reassembles the packets back into the original message. We refer to this process as message segmentation. Figure 1.27 illustrates the end-to-end transport of a message with and without message segmentation. Consider a message that is 8. 106 bits long that is to be sent from source to destination in Figure 1.27. Suppose each link in the figure is 2 Mbps. Ignore propagation, queuing, and processing delays. a. Consider sending the message from source to destination without message segmentation. How long does it take to move the message from the source host to the first packet switch? Keeping in mind that each switch uses store-and-forward packet switching, what is the total time to move the message from source host to destination host? b. Now suppose that…
A frame containing http request is sent from Computer (A) [in whichever subnet it is now, make sure to show it in your figure], to the access point it is associated with. Draw the address fields (1, 2, and 3) of the frame travelling from Computer A to AP and the source and destination addresses of the frame travelling from AP to R1. The MAC addresses of AP1, AP2, and AP3 are M1, M2, and M3 respectively, and the Router R1’s MAC address connected to this Switch/AP is MRA. IP address values are already given, and the port addresses could also be used as given. The Router’s MAC address facing WAN side is MRW.
We compress the video with the pattern GoP (16 : 3) by using MPEG coding. Assume that the average compression ratios of frame I, frame P, and frame B are 1:5, 1:20, and 1:60, respectively. We put the compressed frames in 512 B packets and send them. The header size of each packet is 5% of the size of packet. Each packet contains information on one frame and its header, Each frame can be sent in multiple packets. Picture resolution is 196 × 144 for a video at 32 fps. (a)What is the compression ratio in this pattern? (b)What is the order of coding and transmitting frames in this pattern? (c)If frame 6 is lost while transmission, which frames will be faulty? (d)If frame 5 is lost while transmission, which frames will be faulty? (e)If frame 17 is lost while transmission, which frames will be faulty? (f)Find the size of uncompressed image frame?

When Bob wants to send Alice a message M on the Internet, he breaks M into n data packets, numbers the packets consecutively, and injects them into the network. When the packets arrive at Alice’s computer, they may be out of order, so Alice must assemble the sequence of n packets in order before she can be sure she has the entire message. Describe an efficient scheme for Alice to do this. What is the running time of this algorithm? From Data Structures and Algorithms C-7.56
A bit-oriented sliding window protocol uses frames of 4,848 bits and acknowledgements of 46 bits. The physical layer operates at 0.2 Mbit/s and causes bursts of errors, with typically 8 to 12 bits per burst, at an average rate of 4.8 burst/s. The error bursts can be modelled as a Poisson random process. Calculate the probability of success from the viewpoint of the sender (i.e. the probability of the sender receiving a valid positive acknowledgement for a frame that it sent). Round your answer to 3 decimal places.

Q.No.2. In a network, at physical layer, the sender sends the data in continuous binary stream towards receiver, the receiver get confused about how many bits to combine in order to make the frame because the frames are not of fixed size. What you will suggest to make it work properly, suggest a solution that works on any given string. Please give the help of example also. Note: This question is from computer network.
