20090003200 | SYSTEMS AND METHODS FOR PROTECTING A TRUNK WITH MULTIPLE TRUNKS - A system and method for protecting a trunk with multiple trunks may select a primary path on a first trunk for which to place a corresponding bypass tunnel on a second trunk. The system and method may further select one or more alternate trunks using a constraint-based trunk-selection algorithm. The system and method may further determine if at least one of the selected alternate trunks has sufficient priority bandwidth. In the event that the physical bandwidth of the primary path is larger than the priority bandwidth of each alternate trunks, the system and method may notify a network administrator. In the event that one or more alternate trunks have priority bandwidths larger than the physical bandwidth of the primary path, the system and method may select an alternate trunk from the one or more alternate trunks having priority bandwidths larger than the physical bandwidth of the primary path based on a pre-determined order of priority bandwidth. The system and method may further compare the priority bandwidth of the selected alternate trunk to a threshold value. In the event that the priority bandwidth of the selected alternate trunk is not greater than the threshold value, the system and method may place the selected alternate trunk in a standby status. In the event that the priority bandwidth of the selected alternate trunk is greater than the threshold value, the system and method may place the bypass tunnel on the selected alternate trunk and may set a reserved physical bandwidth for the corresponding bypass tunnel on the selected alternate trunk. | 01-01-2009 |
