Dear Prof
For Paper 10/11 Q6 (a) is it asking node u instead of v? since there is no information about v and it only provides information about u.
Thank you very much~
Regards,
There’s enough information about v to answer the question.
There are two mentions of it before that question (part a) is asked.
It would be very nice to see question 1 in this year’s paper, even if it is just worth 0.5 mark :)
For AY10/11 Q15c (last page),
The question says “After the RTS is successfully sent, the transmitting node sends the data frame immediately”
What does it mean by “the RTS is successfully sent”?
My interpretation is that the node immediately starts transmitting data the moment the RTS is sent out (like immediately after the transmission time of the RTS), without caring whether the RTS has reached anyone.
In that case, it doesn’t seem to work any different from the original scheme.
Or does the question mean “After the RTS has been sent and acknowledged successfully”? As in does the node wait for an acknowledgement for the RTS before transmitting data?
It means that RTS is successfully sent without collision.
Does it mean that RTS is successfully sent without A detecting any collision? Undetected collision can still happen because RTS is very small? So in this way, the only difference from the original scheme is that A will sent a small frame and then the data frame back to back, and if A detect any collision while sending RTS, channel time will not be wasted too much?
Dear prof,
I want to ask about how a router learns about the IP of another router before running the routing protocol ( means when the routing table is empty).
Are them hardcoded?
Thank you.

They obtained other routers’ IP by DHCP?
Very helpful for me))
