TCP session sends 50 packets per second over an Ethernet Local Area Network (LAN). Each packet consists 2280B (excluding the preamble and cyclic redundancy check (CRC)). Calculate the size of the headers, and hence the TCP payload data. What therefore is the TCP throughput of the session?
TCP is a connection-oriented protocol. This means that... O a. both of the endpoints communicating over TCP keep information about the state of the connection. O b. a TCP sender can start sending data to the receiver before the three-way handshake takes place. O c. there is a direct physical connection between the two endpoints of a TCP session. O d. both endpoints of a TCP session have to connect to a third party before data can be sent or received.

Suppose an application generates chunks of 60 bytes of data every second, and each chunk gets encapsulated in a TCP segment and then an IP datagram. What percentage of each datagram will contain application data? A. 20% B. 40% C. 60% D. 80%
An IP address can be written as a 32-bit number. For a class B network, the two most significant bits are set to 10. The 16 most significant bits are used as a network ID, and the 16 least significant bits are used as a host ID. However, the host ID cannot be all O's or all 1's. How many hosts (i.e., host IDs) can there be on a class B network? Type your answer.
14 The following figure shows a TCP transaction. Assume Host A always has data to send, and each packet has size 20 Bytes. Assume Host A has a sending window of 40 Bytes, that is, it can send two "in-flight” packets maximum. Answer the following questions. A. At the time marked "1", i.e., when the first packet times out, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them? B. At the time marked "2", i.e., when the ACK of the 2nd packet is received by Host A, will Host A send any packet? if your answer is no, explain why not; if your answer is yes, how many packets will be sent, what are the sequence numbers of them? Host A Host B Seq=80, 20 bytes of data Seq=100, 20 bytes of data Xª 1 2- timeout
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)?
You would like to send a 2100-byte chunk of data uslng TCP from Computer A to Computer B. TCP segments are carrled In IP datagrams with a 20-byte header. IP datagrams are carrled In a data link frame with a 10-byte header. The maxlmum segment slze for TCP Is 800 bytes. The physlcal layer protocol can support a data rate of 1 Mbps. Assume a total round-trip time of 10 ms between the sender and the recelver. How many frames will need to be sent from Computer A to Computer B? What Is the size of each TCP segment? Show your work
1. What is the difference between packet fragmentation (i.e., at network layer) and frame frag- mentation (i.e., at link layer) in terms of purpose? 2. Suppose that host A is connected to a router R1, R1 is connected to another router, R2, and R2 is connected to host B. Suppose that a TCP message that contains 800 bytes of data and 20 bytes of TCP header is passed to the IP function at host A for delivery to B. Show the Total length, DF, MF, and Fragment offset fields of the IP header in each packet transmitted over the three links. (Assume that link A-R1 can support a maximum frame size of 1024 bytes including a 14-byte frame header, link R1-R2 can support a maximum frame size of 512 bytes, including an 8-byte frame header, and link R2-B can support a maximum frame size of 432 bytes including a 12-byte frame header.) (*hint: the Fragment offset field is denominated by 8-bytes, not bytes) 3. What is the purpose of the path MTU discovery process (see textbook Figure 5-42) and why does…
A workstation uses the HTTP protocol to download a large file from a web server. No proxy server is used. One router's queue is full when one of the web server's packets arrives.Select the four best statements to describe this situationa. The router stores the packet until such time that it can be sent.b. Further packets sent by the server are transmitted at a higher rate to compensate for the lost packet.c. The router sends an ICMP link congested message to the server.d. The packet must be retransmitted.e. Router configuration and network behavior could be improved by configuring FQ or WFQ.f. Further packets sent by the server are transmitted at a lower rate to reduce the load on the congested link.g. Router configuration and network behavior could be improved by configuring RED or WRED.h. A tail drop will happen.
Computer Science In Python, I am trying to make a client and server code that passes the payload with the requirements. The client has to specify the length of the data packet, up to max, specify how many times to pass the data packet, and specify the server IPv4 address. Both the client and the server need timer functions and compute the time needed to perform the number of sends both the Client and the server need to display the local and remote IPv4 addresses, total time, and bytes per second. Please help, Thanks.
Host A sends the information of size 3000 bytes to Host B using TCP protocol. As long as Host B receives each packet in size 1000 bytes, Host B must acknowledge Host A. We assume the header size in each packet is 40 bytes, the starting sequence number used by Host A is 1000, and the window size of the sender side is 3000 bytes. What is the value of RCV.NXT in Host B when the second packet in Host A is sent out and acknowledged? Question options: 1000 2000 3000 4000
