level graph means u r simply making a rooted tree where every node is at a shortest distance from root. also the sink is at a shortest possible level from the src.

blocking flow means after u convert the residual graph into a level graph u pass maximum flow through the level graph and when it becomes impossible to send any flow further for the current level graph.

then again u make another possible level graph

i learned it recently and solved few problem with it.
