[e2e] About TCP modeling in an asymmetric link

[Wei Wu]

Hi, all,

Recently there are many works on TCP performance modeling and TCP-frieldly 
congestion control and the performance of TCP with a bottleneck on the data 
path are well modeled, such as the well-know 1/sqrt(p) law, which the concept
of "TCP-friendly" is based on. However, I wonder that, when the bottleneck 
of the TCP connection is on the ACK path, the forward path loss rate p_f and
the backward path loss rate p_b both existed (moreover, p_f<<p_b), how we 
can get performance evaluation and whether the traditional TCP-friendly 
protocols are friendly in this case. How should we consider p_b in the 
TCP-friendly equation and how to measure it?

I wonder whether there are any works on this problems. Any hint is helpful.
Thanks!
