Abstract
A Line Card Manager (LCM) and Node Manager architecture for use at an optical switch in an optical communications network. LCMs are provided for managing different line cards at the switch, and a Node Manager at the switch manages the LCMs. The Node Manager and LCMs exchange messages using a message-passing interface. The messages may include, e.g., read messages that enable the node manager to retrieve monitored parameter values that the LCM receives from its line card, write messages that enable the node manager to write provisioning data to the LCM, alarm messages that allow the LCMs to report alarm conditions to the node manager, an audit message that enables the node manager to verify a presence of the line card at the optical switch, and discovery messages that allow a LCM to announce its presence to the node manager, e.g., after rebooting.
