- In protocol rdt3.0, the ACK packets flowing from the receiver to the sender do not have sequence numbers, although they do have an ACK field that contains the sequence number of the packet they are acknowledging. Why is it that ACK packets do not themselves require sequence numbers?In a protocol that uses 5 bits for the sequence-number field, if a packet has the sequence number x, how many packets need to be sent to see a packet with the same sequence number x, assuming that each packet is assigned one sequence number?The ACK packets that pass from the recipient to the sender do not have sequence numbers in protocol rdt3.0, but they have an ACK area that includes the packet sequence number they are recognizing. Why does it not need sequence numbers for our ACK packets?
- In a TCP data packet, if the sequence number has the value 001111, ACK number has the value 010110 and the urgent pointer has the value 001100 assuming that URG flag is set. What is the last urgent byte in the data section of the packet? All numbers are in binary.a technique used by protocols in which a lower level protocol accepts a message from a higher level protocol and places it in the data portion of the low level frame is used for encapsulation why?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
- The routing technique FLOODING is used in certain contexts. It means that Group of answer options Incoming packets are sent out on all router interfaces except where they came from. Incoming packets are sent out on all router interfaces. Incoming packets are sent out on the fastest router interface.

- TCP/IP uses packet switching for its routing decisions, where information is split into packets and each packet is routed independently through the network. What is a packet header? What does encapsulation/decapsulation mean?What relationship is needed between sequence number size and window size to avoid problem in recognizing between new transmission and re-transmission in the SR protocol?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?
