ABSTRACT:
An apparatus for selecting a route in a packet-switched network where a plurality of candidate routes are available between a sending node and a receiving node. Total capacity calculation unit disposed in the sending node calculates the total channel capacity of each candidate route by summing up channel capacities of the inter-node links between the sending node and the receiving node. First selection unit chooses the candidate route(s) that exhibit the largest value of the total channel capacity. Uniformity calculation unit is activated when the first selection unit selected a plurality of candidate routes. The uniformity calculation unit calculates uniformity of each candidate route by evaluating the channel capacities of the inter-node links. The second selection unit chooses one of the candidate routes based on the calculated uniformity. This route will be used in packet transmission from the sending node to the receiving node.
