TCP Network Calculus:
The case of large delaybandwidth product.

Abstract--- We present in this paper an analytical model
for the calculation of network load and drop probabilities in
a TCP/IP network with general topology. First we formulate
our model as a nonlinear complementarity problem. Then
we transform the model into two equivalent formulations:
fixed point formulation and nonlinear programming formu
lation. These equivalent formulations provide efficient com
putational procedures for the solution of our model. Fur
thermore, with the help of the fixed point formulation we are
able to prove the existence of a solution. Our model has the
main advantage of not requiring the predefinition of bottle
neck links. The model also takes into account the receiver
congestion window limitation. Our approach can be used
for TCP/IP networks with drop tail routers as well as for
TCP/IP networks with active queue management routers.
We solve the problem for some network examples and we
