Embedded controller architecture for a modular optical network, and methods and apparatus therefor
First Claim
1. A management architecture for use at an optical switch in an optical network, comprising:
- a line card manager at the optical switch for managing an associated line card at the optical switch;
said line card manager comprising;
(a) a first interface for receiving monitored parameter values from the line card;
(b) processing resources for setting an event regarding the line card when criteria for setting the event is met by the monitored parameter values; and
(c) a second interface for communicating the event to a node manager at the optical switch that manages the line card manager.

Abstract
A Line Card Manager (LCM) architecture for use at an optical switch in an optical communications network. A LCM with a dedicated processor is provided for different line cards at the switch. The LCM includes a first interface, such as a connector to the line card, for receiving monitored parameters from the line card, and a processor that executes software for determining when an event such as a fault should be set, e.g., when a monitored parameter is out of range. The LCM has a second interface to a local area network at the switch for reporting the event to a Node Manager, which manages the LCM. The LCM is preferably a removable plug-in module of the line card to allow easy upgrades and maintenance. The LCM includes generic software for managing different types of line cards.
