Host A sends a UDP datagram containing 8880 bytes of user data to host B over an Ethernet LAN. Ethernet frames may carry data up to 1500 bytes (i.e. MTU = 1500 bytes). Size of UDP header is 8 bytes and size of IP header is 20 bytes. There is no option field in IP header. How many total number of IP fragments will be transmitted and what will be the contents of offset field in the last fragment?
A UDP packet is to be sent to a network with MTU=1460 Bytes. The size of UDP data field is 2992 Bytes. Assume this packet is fragmented when traversing the network. Please give the values for the following IP header fields in each IP fragments: Total Length, MF and Offset. Note: Assume IPV4 is used. There is no option field in IP header, i.e., the size of IP header is 20 Bytes. The size of UDP header is 8 Bytes. All numbers are in decimal.
The first portion of IPv4 header of an FTP datagram packet is shown below. Offset 0 4 Header Data 0x48007000 OxA0120000 If the datagram was received by a router that is connected to a network with maximum transmit unit (MTU) = 0x3000. Show the headers of the resulting fragments transmitted by the router. Hint: 1) The first few fragments will have total length = MTU. 2) Fragmentation offset refers to datagram payload, not the fragment Fragmento Offset Header Data 0 4 Offset 0 4 Fragment1 Header Data Blank # 1 Fragment2 Offset Header Data 0 4 Blank1 Blank2 Blank # 3 Blank # 4 Blank # 2 Blank # 5 Blank3 Blank4 Blank # 6 Blank5 Blank6 N A A/ A/

Provide short answers to the following: How do you determine whether an IP address is a multicast address? What is the TTL field in the IP header used for? What is the maximum length of options bytes that can be carried in an IPv4 header? Why do we have to multiply the offset field of an IP datagram by eight to obtain the real offset for the first byte of the datagram?
IP datagrams on a specific network can carry a maximum of only 440 bytes in the data portion. A node on this network, running an application using TCP generates a TCP segment with 1,900 bytes in the data portion. How many IP packets are transmitted to carry this TCP segment, and what are their sizes (including the header of 20 bytes)?
Consider 2 hosts, Host A and Host B, transmitting a large file to a Server C over a bottleneck link with a rate of R kbps. To transfer the file, the hosts use TCP with the same parameters (including MSS and RTT) and start their transmission at the same time. Host A uses a single TCP connection for the entire file, while Host B uses 9 simultaneous TCP connections, each for a portion (i.e. a chunk) of the file. Describe the relative transmission rates achieved by each host at the beginning of the file transfer?
3) Suppose a host transmits a 3500 byte IP packet over a link with an MTU of 500 bytes. Assuming that IP header does not contain any options, indicate the length (in bytes), more flag, and offset field values (specify the offset values in units of 8 bytes) of the fragments transmitted over the link in the table below. Fragment Length Offset Flag 1 3 4 7 8.
For a given an IP v4 datagram, with header fields: HLEN - 5. Total length - 2220 and flag field (RDM) - 000. If this datagram is required to pass through a network of MTU - 1164 byte and need to be fragmented, choose the correct answer 1_For the given packet, the header size is 10 bytes 20 bytes 40 bytes 30bytes 2_The number of fragments to which the given packet is fragmented to pass through the network of MTU: 164: three Tour two Six Network Ineed answer after 30 min
Consider an IP packet with a length of 4,500bytes that includes a 20-byteIPv4 header ans 40-byte TCP header. The packet is forwarded to an IPv4 router that supports a Maximum Transmission Unit (MTU) of 600bytes. Assume that the length of the IP header in all the outgoing fragments of this packet is 20bytes. Assume that the fragmentation offset value stored in the first fragment is 0. The fragmentation offset value stored in the third fragment is
Create a chart that begins with the OSI Seven-layer model on the left-hand side. Next, a column that describes the function of the layer. Then a column that lists the Protocol Data Units (such as Datagrams, Frames, etc) that correspond to each layer in the OSI model. Continue this process for the major hardware or software applications that function in each layer (not all layers have corresponding applications). The last column should be the TCP/IP model aligned to the appropriate layers of the OSI seven-layer model. This should result in a document that looks something like the chart tab (with the blank spaces filled in!)
Maximum Transmission Unit (MTU): Longest prefix matching: IP Fragmentation: Consider sending a 2,400-byte datagram into a link with a MTU of 900 bytes. Suppose the original datagram has the identification number 422. (a) How many fragments are generated? (b) For each fragment, what is its size, what is the value of its identification, fragment offset, and fragment flag? Length ID Fragment Flag Offset
