Question

In BitTorrent, suppose Alice provides chunks to Bob throughout a 30-second interval. Will Bob necessarily return the favor and provide chunks to Alice in this same interval? Why or why not?

Answer 1

Answer:

In BitTorrent, It is not necessary that Bob will also provide chunks to Alice.

Alice has to be in the top four neighbours of Bob and send message to her, this might not occur even if Alice is provides chunks to Bob throughout a 30-second interval.
