Abstract

In data transfer between first and second nodes, such as bridges used to transfer data between local and remote Storage Area Networks (SAN), a parameter optimisation routine is carried out. Initial values of parameters (e.g. window and packet size, number of connections) are obtained by simulated data transfer. A first performance score is then calculated for a data transfer using the initial parameter values. The data transfer may be actual data or simulated. One of the parameters is then varied for a further data transfer and a second score is obtained. The varied parameter value is updated based on the difference in scores. A second parameter value is then varied and the process repeated. The procedure ends when it is determined that an optimum performance criterion has been met. More than two parameters may be varied in the procedure.
