A client process sends a message $m$ to

its NTP server at its time $18ms.$ The

receiver receives $m$ at its time $24ms$ and

sends back a reply $m^{\text{'}}$ at its time $27ms$ by

timestamping its reception and sending

times. The sender receives this message at

its time $25ms.$ What is the round trip time

$($RTT$)$ according to sender and what should be the corrected time of the sender$?$

$2.$Find the logical clock values for each event in Fig. $1\mathrm{.}10.$ Run the Python code for

logical clocks and compare the values obtained by the program with the values calculated

manually.

Find the vector clock values for each event in Fig. $??.$ Run the Python code for vector

clocks and compare the values obtained by the program with the values calculated

manually.

Find the matrix clock values for each event in Fig. $??.$ Run the Python code for logical

clocks and compare the values obtained by the program with the values calculated

manually.
