@Deepak Poonia @Sachin Mittal 1 Sir please check this

https://uniteng.com/wiki/lib/exe/fetch.php?media=classlog:computernetwork:hw2_report.pdf

Question no 8 from this pdf (mentioned in video solution)

From the reference question that sachin sir mentioned in the video solution : they have also considered one RTT for the base HTML file. I think the answer should be 9 RTT in non persistent pipelined and 6RTT in persistent if we consider the connection for base HTML file.


Non persistent with 5 parallel connections :
3 RTT (for DNS ) + 2 RTT (TCP connection and Base HTML file) + 2 RTT (TCP connection and 5 objects in parallel) + 2 RTT (TCP connection and 5 parallel objects) = 9 RTT

Persistent HTTP :
3RTT (for DNS) + 1RTT (TCP connection) + 1RTT (HTML base file) + 1RTT(for 10 objects) = 6 RTT

I think we should need connection for base file in HTTP non-persistent with a parallel connection. so a total of 9 RTT. Please correct me if Iā€™m wrong.
