Claim One:
1. A method comprising: homing, using a computer processor, to an access node that has not been previously used as an access node; determining if the access node has desired egress requirements; in response to determining that the access node has the desired egress requirements, indicating the access node as an egress node and indicating a route from an origin node to the access node as a route choice; and in response to determining that the access node does not have the desired egress requirements, homing to a second node that has the desired egress requirements and has not been previously used as an egress node, indicating the second node as an egress node, and indicating the route from the origin node to the access node to the egress node as the route choice; and determining if a distance from the origin node to the egress node is less than a sum of a first tolerance factor and a distance from the origin node to the access node; in response to determining that the distance from the origin node to the egress node is less than the sum of the first tolerance factor and the distance from the origin node to the access node, eliminating the access node from the route, indicating the access node as not having been previously used as an access node, and indicating the route from the origin node to the egress node, without inclusion of the access node, as the route choice; in response to determining that the distance from the origin node to the egress node is not less than the sum of the first tolerance factor and the distance from the origin node to the access node, maintaining the route choice.
