Patent ID: 7421198

Claim:
A method for implementing an optical network reconstruction comprising: a) an operating system (OS) receiving physical information needed for the optical network reconstruction; b) the OS calculating data needed to be modified for the optical network reconstruction based on the physical information and data related to the optical network reconstruction and stored in the OS, wherein the data needed to be modified comprises data needed to be modified at an OS side and data needed to be modified at a Network Element (NE side); c) the OS modifying the data needed to be modified at the OS side according to the calculation in b) and delivering the data needed to be modified at the NE side to at least one Network Element NE; and wherein the modification in c) is divided into sub-steps, and c) further comprises: the OS judging whether a sub-step is successful after the sub-step is executed, if the sub-step is successful, the OS storing the modified data and going to the next sub-step, and otherwise, the OS recovering any data having been modified from the sub-steps in a reversed order and rolling back to an original state before the optical network reconstruction.
