Optical fiber scheduling method and device

Abstract

The invention provides an optical fiber scheduling method and device. The method comprises the steps of: acquiring node information of an optical fiber network to be scheduled and a physical distance between any two directly connected nodes; establishing a residual optical fiber resource table according to the node information, wherein the residual optical fiber resource table comprises residual optical fibers resources between any two directly connected nodes; detecting whether all the residual optical fiber resources meet a predetermined standard or not; if so, generating a first shortest path between a source node and a target node according to the physical distance between any two nodes, wherein the source node and the target are connected indirectly, and the first shortest path comprises at least two sub-paths formed from the two directly connected nodes; receiving an optical fiber scheduling request carrying the source node and the target node; and responding to the optical fiber scheduling request, completing optical fiber scheduling according to the first shortest path, and updating the residual optical fibers according to the optical fiber resources occupied by each sub-path of the first shortest path.

Description

technical field [0001] The invention relates to routing technology, in particular to an optical fiber scheduling method and equipment, and belongs to the field of communication technology. Background technique [0002] Optical fiber is an important part of the carrier's basic network. In network planning, optical fibers are often laid between each site, and then dispatching engineers design routes according to actual needs, and then jump or fuse optical fibers between optical distribution frames (ODFs) at the sites. [0003] In the current optical fiber routing design, the scheduling path is generated between the source node and the target node pair mainly based on the scheduling engineer's familiarity and experience with the local optical fiber network. The optical fiber routing scheduling realized in this way requires too much manual dependence. As the complexity of the network continues to increase, it cannot be guaranteed to schedule according to the optimal path betwe...

Problems solved by technology

The optical fiber routing scheduling achieved in this way requires too much manual dependence

As the complexity of the network continues to increase, it is impossible to ensure that the scheduling is performed according to the optimal path between the source node and the target node

In addition, fiber scheduling in this way may also lead to fiber scheduling failure due to the continuous reduction of available fiber resources in the actual use of fiber optic networks
