Abstract
A node management architecture for use at an optical switch/node in an optical communications network. A software task is provided for managing each line card according to a type of the line card. The architecture may identify the line card type, and assign a corresponding software task to manage it. To avoid delays, unassigned software tasks may be created ahead of time for managing line cards that are later installed at the optical switch. Furthermore, different types of software tasks are provided for managing corresponding different types of line cards, while software tasks that manage the same type of line card may be organized as an array of the same type. Moreover, the software tasks may act as an intermediary between the line card managers and other software processes at the node manager, such as a database manager, alarms manager, or optical cross-connect manager.
