METHOD FOR COMPUTING A BACKUP PATH FOR PROTECTING A WORKING PATH IN A DATA TRANSPORT NETWORK |
摘要 |
<p>A method for computing a backup path for protecting a first working path in a data transport network that includes a plurality of working paths. The method includes determining a route of the backup path by selecting individual backup path segments from a set of possible segments in the data transport network. In the case of a segment that is shared between the first working path and one or more other working paths, the selection process takes into account the existence of a potential point of failure common to the working paths sharing the segment.</p> |
