Question

Following figures show some UART packets that were sent from one device to the other. The packet
configuration in this case is 811, i.e. 8 Data Bits, 1 Parity Bit and 1 Stop bit. The parity should be even.
i.e. the parity bit should be 1 if the number of is in the data bits are odd, otherwise the parity bit will be
0. It is possible that the data in some packets is corrupted. Determine such packets and provide a possible
candidate of the uncorrupted data that was originally sent, provide these data bits as a binary number
instead of drawing it. Also, calculate the baud rate being used.

Please give me correct solution.
The message to be sent from source to destination is 4000B. The link MTU's from source to destination are 1500, 1000, and 750. If we DO NOT use Path MTU, what are the respective fragment sizes to be reassembled? If we DO use Path MTU, what are the respective fragment sizes to be reassembled? Remember, assume that the L3 and L4 headers have length=0.
Consider a sender having an infinite number of frames to send, which we index as 0, 1, 2, .... Assume the transmission delay of each frame is 2t, the ACK transmission time is t, the propagation delay is 3t and symmetric on both directions, and the timeout value is T = 8 starting from the end of frame transmission onto the link. The first frame is sent out at time 0. Show Transcribed Text 3 Ĉ E. Explain what will happen if the sequence number space has exactly the same number of sequence numbers as the number of allowed maximum number of outstanding frames, e.g., when N = W = 10, and the sequence numbers available are only 0-9.

6. Delays. A user in Madagascar, connected to the internet via a 100 Mb/s (b-bits) connection retrieves a 250 KB (B-bytes) web page from a server in Tokyo, where the page references three images of 500 KB each. Assume that the one-way propagation delay is 82 ms and that the user's access link is the bandwidth bottleneck for this connection. a. Approximately how long does it take for the page (including images) to appear on the user's screen, assuming non-persistent HTTP using a single connection at a time? (For this part, you should ignore queueing delay and transmission delays at other links in the network) How long does it take if the connection uses persistent HTTP (single connection)? b. c. Suppose that user's access router has a 4 MB buffer (B-byte) on the link from the router to the user. How much delay does this buffer add during periods when the buffer is full? d. Assume a cache rate of 45% on the information received by the user in Madagascar from the Tokyo server. How does…
It is possible for a series of packets to be sent from one host to another over the same connection. Please break down the time it takes for a single package to go from beginning to conclusion. Is it expected that one of the delays would last a certain period of time while the other delay's length will be more malleable?
Suppose Alice and Bob are going to communicate using AES in CBC mode. Unfortunately Alice's message length (in bytes) is not a multiple of 16. Suppose the last block of her message is just a single zero byte. How can she pad out the last block so that she can use CBC mode? Since this needs to be a reversible operation, how does Bob recognize the padding and remove it?
Let's imagine, for the sake of illustration, that a packet is now being sent from one site to another along a predetermined route. The following is a list of the components that make up the delay: Which of these delays is an ongoing problem, and which of them is sporadic in nature?
To ensure the quality of service, especially for multiple applications, regulating the rate at which packets are sent to the network is an important strategy. The leaky bucket is just one of such mechanisms. A flow of packets is said to conform to the leaky bucket specification (r, b), where r is the average rate and b is the burst rate, if the number of packets arriving at the leaky bucket is less than r*t + b in every time interval of t. What is the implication of that? What will happen if the number of packets arriving at the leaky bucket is equal to or greater than r*t + b?
Please solve it correctly. You receive a packet whose data length is 900 bytes, ID is 2398 and the MF flag is set to 0.You received the remaining 12 packets, each of whose total length is 1945 bytes, ID is 2398and the MF flag is set to 1. All of these packets’ header size is 25 bytes.I. Find the packet size of the original datagramII. Find the value of the offset field of the 2nd last packet [First data byte number starts at0]III. How would you identify the last packet in a group of fragmented packets?
