Latest Patents
Tzathas's latest patents include a "Multi-tiered control architecture for adaptive optical networks, and methods and apparatus therefor." This invention presents a hierarchical and distributed control architecture designed to manage an optical communications network. The architecture features a line card manager level for overseeing individual line cards in an optical switch, a node manager level for managing multiple line cards, and a network management system level for coordinating multiple optical switches/nodes. An event manager at the node manager level allows software components to register for and receive events, which may be triggered by changes in switch status or alarm conditions. The control architecture encompasses functionalities such as signaling, routing, protection switching, and network management, which includes a topology manager, performance manager, connection manager, fault detection manager, and configuration manager.
Another significant patent is the "Node architecture for modularized and reconfigurable optical networks, and methods and apparatus therefor." This invention describes an optical transport switching system featuring an all-optical switch that can be configured for cross-connection and add/drop multiplexing functions. The system includes optical circuit cards housed in a chassis and connected via an optical backplane. These cards may consist of access line interface cards, optical access ingress cards, transport ingress cards, transport egress cards, and optical access egress cards. The optical switching fabric facilitates selective optical coupling between the cards, enabling the all-optical switch to function within an optical network that accommodates external/access networks, including those utilizing Gigabit Ethernet or SONET signaling. Wavelength conversion is also provided for non-compliant wavelengths of access networks.
