What's the use of running the server software before the client program in a TCP client-server application? Why may the client software run before the server program in a UDP client-server application?
QUESTION 13 Fill the blank With the TCP server, there is a welcoming socket, and each time a client initiates a connection to the server, a new socket is created. Thus, to support n simultaneous connections, the server would need sockets. O n-1 On O n+1 01
Draw a complete TCP 3-way handshake logical diagram of an HTTP session with a website session.
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)?
Which of the following three features best defines TCP in contrast to UDP?
In Section 5.7 we saw that it was preferable to transport SNMP messages in unreliable UDP datagrams. Why do you think the designers of SNMP chose UDP rather than TCP as the transport protocol of choice for SNMP?
The UDP server only required a single socket, while the TCP server required two sockets to function properly. Why? How many sockets would the TCP server need if it could handle n connections from various client hosts at once?
IP is a connectionless protocol, while TCP is a connection-oriented protocol. What is the best approach to cohabit these two protocols in the same protocol stack?
Draw a complete TCP 3-way handshake logical diagram of an HTTP session with a website session with TCP 3-way handshake with the appropriate flowchart modules such as the start, decision, action and stop modules
13. The following figures plot the timeline for sending TCP segments by host A and TCP ACKS by host B, where “seq #” is the value of the sequence number in the TCP header, and "ACK #” is the value of the acknowledge number in the TCP header. Assume that every segment always includes 500 bytes of data, excluding the TCP header. A seg #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (1) B ACK #: a ACK #: b ACK #: c ACK #: d A seq #: 1000 seq #: 1500 seq #: 2000 seq #: 2500 (2) B ACK #: r ACK #: s TACK 1) In Figure (1), the second ACK sent out by host B gets lost in the network. a) What are the acknowledge numbers a, b, c, and d? b) Will sender A think the segment with seq#=1500 was lost because it never receives the acknowledgement from B containing ACK# = b? 2) In Figure (2), the second TCP segment from host A to host B gets delayed in the network but later arrives at B. What should be the value for the ACK number r, s and t?
We said that a program should use UDP for a transport layer protocol because UDP has better control over when the data is sent to a section and when (the TCP). A. Why does the program have more power about which data is sent into a segment?
IPV4 is a Connection oriented Protocol. * False True Broadcast is the process of sending a packet from one host to a selected group of hosts. * False True The prefix length is the number of bits in the address that gives the Host portion. " False True The metric is used to decide which route appears on the routing table. * True False The throughput value is greater than The Bandwidth Value. * True False O O O O
