Abstract
A method and apparatus for controlling routing within a communication system (10) modifies (258) routing tables (220, 230, 232, 234, 236) located within nodes (150) so that received data packets are not returned directly to their sending nodes. In response to detection (352) of a failed link, a node (150) modifies (354) its routing tables (220, 230, 232, 234, 236) to avoid the failed link. After notification (402) of the failed link, a control facility (28) responds by creating (404) commands that compensate for the failed link. The control facility (28) sends (404) the commands to at least the node (150) that detected the failed link. If not already performed by the control facility (28), the node (150) then modifies (364, 366) its routing tables (220, 230, 232, 234, 236) so that data packets are not returned to their sending nodes, and to avoid the failed link.
