摘要： Switching architectures for WDM mesh and ring network nodes are presented. In mesh networks, the switching architectures have multiple levels—a network level having wavelength routers for add, drop and pass-through functions, an intermediate level having device units which handle add and drop signals, and a local level having port units for receiving signals dropped from the network and transmitting signals to be added to the network. The intermediate level device units are selected and arranged for performance and cost considerations. The multilevel architecture also permits the design of reconfigurable optical add/drop multiplexers for ring network nodes, the easy expansion of ring networks into mesh networks, and the accommodation of protection mechanisms in ring networks.

摘要： The present invention provides a directionless optical architecture for reconfigurable optical add/drop multiplexers (ROADMs) and wavelength selective switches (WSSs). The directionless architecture utilizes a directionless wavelength switch coupled between client devices and ROADMs/WSSs to eliminate the need to hard-wire client devices to a wavelength division multiplexed (WDM) network. Accordingly, client device connections can be automatically routed without manual intervention to provide a highly resilient network design which can recover route diversity during failure scenarios. Additionally, the present invention minimizes deployments of costly optical transceivers while providing superior resiliency. Further, the present invention couples the directionless optical architecture and associated optical protection mechanisms with existing mesh restoration schemes to provide additional resiliency.

摘要： An asymmetrical and dynamic routing system (ADRS) is provided to enable the dynamic adjustment of the bandwidth capacity of two or more network devices exchanging data. The two or more network devices monitor their current bandwidth demand between themselves and others in a network and a first network device can transmit bandwidth request to a second network device when the first network device reaches transmission bandwidth capacity. Each network device is further configured with additional transmit and receive ports and can be selectively enabled in response to a bandwidth request from other network devices. Each network device is further configured to generate control signals that are sent to optical mirrors to re-direct data signals to or from the one or more enabled additional transmit and receive ports.
