POTN NETWORK ODUK RING PLANNING METHOD AND DEVICE

摘要

The embodiments of the present disclosure provide a method, a device and a computer storage medium for planning an ODUk ring planning in a POTN. The method includes: acquiring a physical topology and a ring topology; acquiring node information of a ring network service needing ring protection and searching the ring topology for a path according to the node information of the ring network service; when finding a path on the ring topology is failed, searching, on a combined map of the physical topology and the ring topology, for two shortest paths with nodes separated; constructing an ODUk ring of the ring network service using the two shortest paths with nodes separated, and updating the ODUk ring into the ring topology.
