ABSTRACT:
The network operating system includes an embedded platform for controlling operation of an agile optical network at the physical layer level. At the module embedded level, each module (card-pack) is provided with an embedded controller EC that monitors and control operation of the optical modules. At the next level, each shelf is provided with a shelf processor SP that monitors and control operation of the ECs over a backplane network. All optical modules are connected over an optical trace channel to send/receive trace messages that can then be used to determine network connectivity. At the next, link management level, a network services controller NSC controls the SPs in a negotiated span of control, over a link network. The control is address-based; each NSC receives ranges of addresses for the entities in its control, and distributes these addresses to the SPs, which in turn distribute addresses to the ECs in their control. One of the SPs operates as a router on the link network to relay signaling and control to all entities based on their address. Each NSC constructs, from queried information, a network topology fragment for the embedded elements under its control. A distributed topology system (DTS) shares this topology information with neighboring NSC's to build a complete network view, which can be used by all interested network applications.
