QUESTION 19 Suppose a process in Host C has a UDP socket with port number 4320. Suppose both Host A and Host B each send a UDP segment to Host C with destination port number 4320. Then both of these segments will be directed to the same socket with port number 4320 at Host C True False QUESTION 20 With TCP’s flow control mechanism, where the receiver tells the sender how much free buffer space it has (and the sender always limits the amount of outstanding, unACKed, in-flight data to less than this amount), it is not possible for the sender to send more data than the receiver has room to buffer. True False
Consider the Scenario network. Suppose all hosts A and B have such set timeout values. a. Argue that increasing the size of the router's finite buffer may decrease output (out). b. Now suppose that all hosts change their timeout (like TCP) dynamically on the basis of the buffer time on the router. Will the buffer size increase help to increase the output? Why?
consider 3 hosts (A , B and C) where A is running 3-TCP process, B has 1-TCP process and C is running 2-UDP process all process are trying to connect to a web server to download a file . How many new socket(s) will be created at the server side? Explain why?
Suppose that a Web server runs in Host C on port 80 . Suppose also that this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. a) Are all of the requests being sent to the same port number at Host C? b) Will the client use port 80 in its local machine to communicate with the server? c) How does the server differentiate between the two requests?
Suppose that a Web server runs in Host C on port 80. Suppose this Web server uses persistent connections, and is currently receiving requests from two different Hosts, A and B. Are all of the requests being sent through the same socket at Host C? If they are being passed through different sockets, do both of the sockets have port 80? Discuss and explain.
Consider the network shown in Scenario 2 in Section 3.6.1 . Suppose both sending hosts A and B have some fixed timeout values.a. Argue that increasing the size of the finite buffer of the router might possibly decrease the throughput (? ).b. Now suppose both hosts dynamically adjust their timeout values (like what TCP does) based on the buffering delay at the router. Would increasing the buffer size help to increase the throughput? Why?
Let's say that Host C is running a Web server that listens on port 80. Suppose that this web server is able to maintain persistent connections and responds to requests from both Host A and Host B. Is Host C sending all of the requests over the same connection, or are there many sockets in use? Do each of them have port 80 even though they are broadcast over separate sockets? It's something you need to discuss and provide some clarification on.
Detailed assessment involves scanning all 65,536 TCP and SCTP ports for each IP address withinscope, along with testing of common UDP ports (to save time). I have yet to find a UDP servicerunning on a nonstandard port during testing, and so running a UDP scan with Nmap’s default serviceslist is sufficient
a) Host A uses TCP to transfer a file to host B. The file contains 24 MSS (maximum segment size) worth of data. During the transmission Round 1 (that corresponds to one RTT), the congestion window is 1 MSS. During Round 4 when the connection is still in slow start, all the transmitted packets are lost. Assume that host A times out at the start of round 8 (i.e. it is idle in rounds 5 to 7). What is the Slow Start threshold at this point? Show detailed analysis. b) Assuming that there is no packet loss during any other round. During what data transmission Round does B receive the complete file? Ignore connection establishment and termination and assume that the RTT is large enough that transmission time is negligible. Show your detailed work
Assume Host C runs a Web server on port 80. Assume that this Web server accepts requests from Hosts A and B and that persistent connections are enabled. Is Host C sending all of the requests through the same socket? Do they both have port 80 if they're broadcast via distinct sockets? It's something you ought to discuss and explain.
Assume Host C is running a Web server on port 80. Assume that Hosts A and B are currently submitting requests to this Web server, which supports persistent connections. Is Host C using the same socket to send all of the requests? If they're being sent over different sockets, does each one have port 80? Discuss it and give an explanation.
