Abstract: In order to enhance collaborations, the system responds to a trigger event to determine the nature of any collaboration which should be assembled in response to the trigger, and determines the requirements needed to respond to the event. These requirements set out the type of resources (personnel, equipment, information systems, etc) that are needed. The system then identifies a subset of specific resources based on a criteria, and invites the specified resources to collaborate to respond to the event. The criteria can include the availability of the specific resource. According to an embodiment, the system evaluates responses from the invited resources and then convenes the collaboration, for example by establishing one or more communication sessions. According to an embodiment, the system evaluates responses from the invited resources to ensure that the requirements are satisfied, and if not, determines other resources to invite.

Abstract: A method of managing access to a healthcare information system of a healthcare establishment communications network. The method comprises receiving data regarding a wirelessly detectable tag associated with a clinician; determining whether the clinician is positioned relative to a terminal of the healthcare establishment communications network such that a proximity condition is satisfied based at least in part on the data regarding the wirelessly detectable tag; responsive to the proximity condition being satisfied, providing an opportunity for authentication of the clinician; and responsive to successful authentication of the clinician, establishing a session for the clinician between the terminal and the healthcare information system. The ability to detect proximity of clinician facilitates the process by which the clinician may access the healthcare information system, while the requirement for authentication of the clinician minimizes the risk of data being made available to an unauthorized party.

Abstract: A communications network for a metropolitan area is disclosed. The network is comprised of three basic types of nodes: an access multiplexer, a photonic switch, and a core node. The access multiplexer provides multiplexing of data packets from end-users onto at least one sparse wavelength division multiplexed (SWDM) wavelength. The SWDM wavelengths are carried over fiber cable to the photonic switches, which consolidate these wavelengths into dense wavelength division multiplexed (DWDM) wavelengths for transmission to the core node. The core nodes include a photonic switch (PSX) and a service-aware terabit router core for routing packets within the metropolitan area via the network or out to a long haul network. The photonic switches and core nodes are capable of switching at the wavelength, group of wavelength, and fiber levels.

Abstract: A connection verification system that provides substantially non-intrusive connection verification for an optical switch, achieved by correlating the low-frequency contents of the input and switched signals. The results of the correlation process are compared against a connection map to determine whether the switch has operated correctly and to identify, if possible, which mis-connections have taken place. The system includes a selection unit for controllably admitting individual ones of the input signals and individual ones of the switched signals and a verification unit connected to the selection unit, for controlling operation of the selection unit as a function of a connection map and performing relative-delay-dependent signal processing operations on the signals admitted by the selection unit so as to identify connections established through the switching unit and determine their consistency with the connection map.

Abstract: A switch for optical signals, including a plurality of external inputs, a plurality of external outputs, a wavelength conversion entity and a plurality of core switching entities. Each core switching entity is associated to a respective set of at least two wavelengths. The approach is based on switching groups of at least two wavelengths in each core switching entity, while still maintaining per-wavelength switching granularity but sharing the provided capacity for wavelength conversion connections across the group. Thus, wavelength conversion resources assigned to a group of wavelengths are usable by any wavelength in that group. In this way, the blocking statistics in the node as a whole are improved with respect to a single-wavelength-plane configuration. In addition, the resulting switch is modular as it can be upgraded by adding or removing one or more switching modules as required.
