Latest Patents

One of Yanhe Fan's latest patents is titled "Supervisory control plane over wavelength routed networks." This invention provides a dedicated IP-based wavelength routing and signaling control plane for optically switched networks. The innovative aspect of this control plane is that it operates as an out-band routing and signaling mechanism, eliminating the need for optical-electrical-optical (OEO) conversion. This design allows the control plane to adapt to various network topologies, ensuring that if a supervisory or control channel fails, the IP-based control plane can efficiently reroute traffic to its destination. Additionally, using non-broadcasting addressable protocols, the control plane can select alternative paths to redirect control information without disrupting the entire communication trail or affecting client traffic over the data path.

Another significant patent by Yanhe Fan is the "Method of optical network bandwidth representation for optical label switching networks." This invention offers generic and flexible methods to represent optical bandwidth and service interfaces for optical label switching networks. The ability to represent bandwidth at various granularity levels and in different combinations simplifies the design and implementation of protocols for optical label switching networks.
