A network protocol contains a four-byte integer, specifying the length of the payload in the packet. The implementation of this protocol has a mistake in it. When a packet is received, the protocol implementation needs to copy the payload to a buffer. It first copies the length field from the packet header to a variable, but the program forgets to convert the number into the host order. Assume the value of this variable is X. The program then allocates X...

a-Suppose that a Piconet bluetooth network contains seven devices. Is it possible to add three more devices to the same network? Justify your answer in your own words. b-In an IPv4 packet, the value of HLEN is 6, and the value of the total length field is (0035)16. How many bytes of data are being carried by this packet?

Dears,, I want unique, complete and correct answers to these questions: Q 1. Assume an organization has the classless address 15.25.16.8/17, then find the following: The first address The last address The total number of addresses The network address Does the address 15.25.15.127 belongs to this address space? Does the address 15.25.128.0 belongs to this address space? Q2. a) In an IPv4 packet, the value of HLEN is (1010)2 , and the value of the total length field is (005A)16....

Note: b denotes bits and B denotes Bytes (1 Byte = 8 bits). Consider a packet of length L, which begins at source and travels over seven links to a destination. These links are connected through six routers. Let di, si, and Ri denote the length, propagation speed, and the transmission rate of link i, for i = 1 to 7. The processing delay at each router is d-proc. The queuing delay at each router is d-que. What is the...

Question 6: An IP packet of size 4576 bytes needs to be sent through a network. If the Maximum Transport Unit (MTU) size allowed by the network is 1536 bytes, the packet will need to be fragmented. Considering that a minimum number of fragments should be used, for each fragment, find the values for: DF and MF flags Fragment offset field Length of each fragment Then answer the...

1. a. In Wireshark, for packet 92, what information in the IP
header indicates that the datagram has been fragmented?
b. What information in the IP header indicates whether this is
the first fragment versus a latter fragment? How long is this IP
datagram?
2. a. For packet 93, what information in the IP header indicates
that this is not the first data fragment? Are there more fragments?
If so, how can you tell?
