GO Classes Test Series 2024 | Mock GATE | Test 12 | Question: 39
Consider a $\text{TCP}$ flow sending three segments, namely $1,2,$ and $3.$ Due to congestion, the $\text{TCP}$ flow experiences exactly two losses. Only segments can be lost; acknowledgments are not lost. Segments $1$ and $3$ are ... for all packets successfully? $\text{3 RTTs}$ $\text{5 RTTs}$ $\text{6 RTTs}$ $\text{8 RTTs}$

Assume the scenario of AIMD where the size of the congestion window of a TCP connection is 40KB when a timeout occurs, the initial threshold is 38 KB. The MSS is 2KB. At which transmission after a timeout the sender window reaches 20 KB? The given ... line At which transmission after a timeout the sender window reaches 20 KB? we need to count from starting or after timeout?

On any given Sunday, Sam initiates a connection with his girlfriend Alice in order to plan out what movie they're going to watch on Tuesdays with Morrie. This Sunday, immediately after Sam initiates the connection, Alice decides to send him a 60 KB ... congestion window of 1. Neglect queuing and processing delays at both the sender and receiver, and assume there are no losses.

which value do we have to return when the question is like this ..what is the window size at the end of nth transmission? do we have to return window size at nth transmission or window size of (n+1)th transmission ...there always comes a single value gap ... to be true in test series and sometimes false? pls clarify this ..don't want to loose marks if this comes in actual gate exam.
