Estimating the term…
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.
A communication node for use in a communication network in which data can be transmitted between a sender and a receiver via at least two different routes, each route comprising at least one link, said node comprising a link management function unit (LMF) arranged to calculate at least one metric value for said at least one link, characterized in that the link management function unit (LMF) is also arranged to calculate a sensitivity parameter value for said at least one metric, said sensitivity parameter being indicative of how the metric would change with a given change in the network.
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 value for at least a first link in the network, characterized by the steps of calculating a sensitivity parameter value for said at least one metric, said sensitivity parameter being indicative of how the metric would change with a given change in the network, and taking said sensitivity parameter into account when selecting a route.
