@arjunsuresh:disqus IF possible discuss
1. Properties of CRC polynomial
2. socket Programming in detail of required for GATE
3. TCP Congestion Control – This whole this in TCP is mess.
I’m good in point 2 & 3. Though I think discussion will be very helpful. No idea about Point 1.

Also there are following questions I would love to discuss ->
http://gateoverflow.in/482/gate2008_59 System calls in Socket API
http://gateoverflow.in/2059/gate2014-3_25 IP Datagram
http://gateoverflow.in/3506/gate2007-it_62 statistical time division multiplexing
http://gateoverflow.in/3772/gate2005-it_26 Traceroute
http://gateoverflow.in/1333/gate2009_47 Sequence no
http://gateoverflow.in/1397/gate2005_74 Ethernet minimum frame size
http://gateoverflow.in/2061/gate2014-3_27 Another Sequence no Question
http://gateoverflow.in/3514/gate2007-it_69 Very Long Protocol Question 🙁
