The first network type we investigate is shown in Figure 3. It is in many senses a trivial nnnteed to the control of the control duced at the sources do not change in time and are listed in Tables 1 and 2, along with the performances of our algorithms.

The MB COIN results are identical to the ISPA results in the absence of the additional link (Network A). However, Braess' paradox arises with ISPA, in that the addition of the new link in network B degrades the performance of the ISPA in six of the eight traffic
