please answer with proper explanation and step by step solution. Question: Consider a fictional six-layer protocol hierarchy where layer 1 is the lowest layer, and layer 6 is the highest layer. Therefore, an application sends a message M by passing it to layer 6. All the even-numbered layers attach a trailer Ti (i = 2, 4, 6) to their payload, and all the odd-numbered layers attach a header Hi (i = 1, 3, 5) to their payload. Draw the headers, trailers, and original message M in the order they are sent out.
6.7-1. To which protocol do these fields belong? We learned way back in Chapter 1 that "a protocol defines the format and the order of messages exchanged between two or more communicating entities ..." and throughout the course, we saw many, many different messages being used throughout the protocol stack, each with different fields. In this question, for a given field name in a protocol message (i.e., in an application-layer message, transport-layer segment, network-layer datagram, or link-layer frame), use the pulldown menu to match the field name with the protocol (or pair of protocols) where this field name is used. Each protocol name (or pair of protocol names) in the pull-down menu should be matched to exactly one field description.
A network system has 5 protocol layers. Applications generate messages of length M bytes. At each of the layers, an h-byte header is added. What fraction of the network bandwidth is filled with headers? a. 5h/(5h+M) b. M/(5h+M) c. M/(4h+M) d. 4h/(4h+M)
8)How do you describe a TCP/IP encapsulation process? a. data is sent from transport to network access layer b. Segments are sent from transport to internet layer c. Bits are sent from transport to internet layer d. frames are sent from internet layer to transport layer
In terms of performance, provide a simplified summary of the pros and cons of connectionless protocols in comparison to connection-based protocols, and compare and contrast the two kinds of protocols.
Assume that the link has an MSS of 100 bytes and that we are using a stop and wait protocol. If we have no packet loss and an RTT of 100ms, what is the utilization of this link?
5. Expand the information on the Transmission Control Protocol for this packet in the Wireshark “Details of selected packet” window (see Figure 3 in the lab writeup) so you can see the fields in the TCP segment carrying the HTTP message. What is the destination port number (the number following “Dest Port:” for the TCP segment containing the HTTP request) to which this HTTP request is being sent?
In a byte-oriented link layer protocol, the receiver adds all the bytes between the start and end marker bytes (not including those markers) modulo 239, and expects to get a result of 0 if there have been no errors. The byte immediately before the end marker is a checksum, chosen at the transmitter to make this possible. The probability of an error in any received bit is 0.00075 . The total length of the frame is 205 bytes (including start and end markers). Estimate the probability of errors occurring in the received frame but not being detected. You need to consider what combinations of bit errors could cause the error detection system to fail (i.e, conclude that there are no errors). As you are asked for an estimate, you need only consider the most likely scenarios - it is safe to ignore events that could only occur with much lower probability. Round your answer to three significant figures. As the probability will be very low in some cases, you may have to enter up to 7 digits after…
In a bit-oriented link-layer protocol, the start and end of a frame are each marked by a flag, which is a sequence of exactly 6 consecutive 1 bits. Bit stuffing is used during the rest of the frame: after sending 5 consecutive 1 bits, a 0 is added. The bits below contain an example frame, with the leftmost bit received first. The content of the frame is a sequence of bytes, sent most significant bit first. Put the values of the first four bytes of the frame content, in order, in the four answer boxes below. You may enter the values in either decimal (e.g. 76, 123) or hexadecimal (e.g. 2a, f7). 00101011111010001111110011100111110000111101111101010110100010010011111101101100100 57−240−123−229
This elementary problem begins to explore propagation delay andtransmission delay, two central concepts in data networking. Consider two hosts, Aand B, connected by a single link of rate R bps. Suppose that the two hosts areseparated by m meters, and suppose the propagation speed along the link is smeters/sec. Host A is to send a packet of size L bits to Host B. d. Suppose Host A begins to transmit the packet at time t=0 . At time t= ?????? ,where is the last bit of the packet? e. Suppose ????? is greater than ?????? . At time t= ??????, where is the first bit of the packet?f. Suppose ????? is less than ??????. At time t= ?????? , where is the first bit of thepacket?
MAC protocols for an access network with N nodes continuously producing data at a constant rate of x bits per second per node are needed, and you are responsible for developing one. The traffic aggregated across nodes is also less than but close to the entire capacity of the access network, which is another positive development. In your opinion, which protocol is preferable: channel partitioning or random access? For this example, let us assume that you have chosen channel partitioning and that the channel has been divided into N subchannels.
A bit string, 0111101111101111110, needs to be transmitted at the data link layer. What is the string actually transmitted after bit stuffng? Write a computer code to do this job.
