They assume that in a stream, the deviation at each point is the same. I am not sure how general that is. Though on the other hand I felt, since the source of a stream is usually same, this assumption is right. (they have used this assumption just below the Figure 3) text/html 2008-10-30T22:36:07+00:00 http://www.rohitj.net/wiki/doku.php?id=songs&rev=1225406167&do=diff * The Doors * Alabama * Hello, I love you * Light my Fire * LA Woman * Touch me * Nirvana * Lithium * Come as you are * In Bloom * Rape me * All Apologies * Plateu * Oh me * Where did you sleep last night text/html 2008-10-24T10:27:29+00:00 http://www.rohitj.net/wiki/doku.php?id=start&rev=1224844049&do=diff Welcome, This wiki is mainly for me to maintain any random notes. Sometimes I also use it to write things which might be useful for others. But in general its just for me.

Now each node is willing to donate s_i storage and b_i bandwidth. * Commit Protocol * We can use any general commit protocol, but the problem is each node wants to donate different storage size (s_i) and each node wants to donate a different amount of bandwidth (b_i). How do we deal with that in a commit protocol? * How to deal with the possibility that nodes might be going off and on. * And how do…
