A combined voice and data routing objective
John K. Antonio · 2002
A smooth approximation of the Weinstein formula for voice freeze-out fraction is derived. The approximation is a continuously differentiable function of offered voice flow rate. As an important application, it is shown that the approximation can be used as a basis for defining objective functions for optimal routing in voice and voice/data networks. The smoothness of the proposed objective functions suggests the use of distributed optimal routing algorithms based on nonlinear programming techniques.>
