Abstract:
1. A device for creating a path between a first element and a second element, the path being arranged to include a third element, wherein the first element, the second element, and the third element are included in an optical network, the device comprising: a processor; and a storage device, the storage device being arranged to store computer code for implementing a first mechanism which causes the third element to be identified, the storage device further being arranged to store computer code for implementing a second mechanism which causes the path between the first element and the second element to be computed such that the path traverses the third element, wherein the processor processes the computer codes and the first mechanism is arranged to identify the third element and a fourth element as being components of the path, the fourth element being arranged to be traversed after the third element is traversed, the path including a plurality of segments which includes a first segment associated with the first element and the third element, the second mechanism being further arranged to compute the first segment, the storage device further being arranged to store computer code for implementing a third mechanism which causes the fourth element and the second element to be substantially prevented from being included as a part of the first segment, wherein the second mechanism is further arranged to compute a second segment associated with the fourth element, the second segment being included in the plurality of segments, and wherein the third mechanism is arranged to substantially prevent the first element and the second element from being included as a part of the second segment.
