Latest Patents

Cunningham's latest patented inventions include:

1. **Communications Network for a Metropolitan Area**: This patent describes a sophisticated communications network composed of three essential types of nodes: an access multiplexer, a photonic switch, and a core node. The access multiplexer efficiently multiplexes data packets from end-users onto at least one sparse wavelength division multiplexed (SWDM) wavelength. These wavelengths traverse fiber cable to the photonic switches, which aggregate them into dense wavelength division multiplexed (DWDM) wavelengths intended for transmission to the core node. The core nodes incorporate a photonic switch and a service-aware terabit router core, enabling effective packet routing within the metropolitan area and extending out to long-haul networks. Notably, the switches and core nodes possess the capability to switch at the wavelength, group of wavelengths, and fiber levels.

2. **Bandwidth Allocation in Ethernet Networks**: This innovation proposes a function designed to assign bandwidth in a constrained topology Ethernet network. It introduces a bandwidth manager that maintains a ledger of bandwidth requests throughout the network. This function tracks total bandwidth across each link and the bandwidth reserved on them. When traffic is allocated reserved bandwidth, the bandwidth manager updates the ledger accordingly. Traffic packets include headers that denote high priority when bandwidth is reserved, allowing the manager to effectively monitor and control high-priority traffic on the network.
