Hi,

I have a question about what is happening in this video at 00:07:33 -

http://www.youtube.com/watch?v=jp0JdeeFUG0#t=453s.

sir A node sends packets to a node B as it sends a query that a received or not if A does'nt get any feedback then it generates duplicates but when a node crashes then all the data is get losted but i want to ask why don't we send to another node as it unable to to find the crased node?.

Thanks!
