Abstract
The invention relates to a method of routing traffic from a sender to a receiver in a communication network said method comprising for at least two possible routes between the sender and the receiver the step of calculating at least one metric for at least one link in each route, characterized by the steps of calculating a sensitivity parameter for said at least one metric and taking said sensitivity parameter into account when selecting a route. The sensitivity parameter may be based on a derivative of said metric with respect to a variable on which said metric depends. The method may also comprise the step of calculating a reliability parameter for said at least one metric and taking said reliability parameter into account when selecting a route.
