3. Better TCP windowing and better performance when all packets follow the same path.
Not really. TCP mostly cares about round-trip, not timing of forward and backward paths.
Really, consider a link where the path carrying most of the data has a time of N and the path carrying the ack has a path 2N or N + 1/2N You are computing an average which seems like it could be skewed based on the path the ack takes. Does anyone know of any papers on the effect of asymetric paths on TCP performance?
