US 7,013,084 B2 · Multi-tiered control architecture for adaptive optical networks, and methods and apparatus therefor

Abstract

A hierarchical and distributed control architecture for managing an optical communications network. The architecture includes a line card manager level for managing individual line cards in an optical switch, a node manager level for managing multiple line cards in an optical switch/node, and a network management system level for managing multiple optical switches/nodes in a network. An event manager at the node manager level enables software components that are running at the node manager to register for and receive events, and to post events. The events may be triggered, e.g., by a change in a status of the switch, or an alarm condition. Control architecture functionalities include signaling, routing, protection switching and network management. Furthermore, the network management function includes a topology manager, a performance manager, a connection manager, a fault detection manager, and a configuration manager.

Dependent claims

A multi-tiered control architecture for an optical network having a plurality of optical switches, comprising:

for each optical switch, respective line card managers for managing respective line cards associated therewith, and a node manager for managing the line card managers;
and
a centralized network management system for managing the node managers of the optical switches;
wherein, at each optical switch, the node manager includes an event manager for enabling software components running at the node manager to at least one of:
(a) register for, and receive, events, and (b) post events.
