Abstract: Optical By-Pass (OBP) links may be created by adding wavelengths between nodes on the network. The OBP may extend between any pair of nodes on the network. Intermediate nodes on the OBP are transient nodes and simply forward traffic optically. An OBP extends between a pair of nodes and, unlike express links, is created in such a manner that it does not affect the previous allocation of resources on the network. This enables capacity to be added between pairs of nodes on the network to alleviate congestion at a portion of the network, without changing other traffic patterns on the network. This enables inclusion of an OBP to be deterministic and of linear impact on the network. The OBP links may be statically provisioned or created on demand. Optionally, the OBP links may be crated to coincide with PBB-TE tunnels on the network.

Abstract: Application program network service requests are translated into specific actions that are then performed through the management plane and/or control plane. The translations and resulting actions are responsive to previously defined policies for the communication network, and may further reflect processing of previous service requests by the same or another application program. The amount of resources available for use by a given application program may be predefined based on a globally defined network policy. Each service request obtained from an application program may be translated into multiple actions performed using various specific protocols and/or interfaces provided by either the management plane, the control plane, or both the management and control planes. Reports of network activity, status and/or faults for a requesting application program may be tailored to the requesting program's view of the network, and passed directly and exclusively to the requesting program.

Abstract: Collection of topology mapping linkage information between a Storage Area Network (“SAN”) and a transparent interconnecting transport network is at least partially automated. Physical topology information is gathered by detecting use of a physical path between a port of a first SAN device and a port of a second SAN device logically proximate to the transport network. This may be accomplished by discovering World Wide Names of end-points in a Fibre Channel SAN, and discovering Media Access Control addresses of end-points in an Ethernet SAN. The discovered physical topology information is then employed with known transport network logical topology information to determine which logical path or paths are associated with the physical path, i.e., to generate a mapping.

Abstract: A method and apparatus for securing an optical communication link includes the step of identifying a profile of the link by measuring, at the transmitter, optical back-reflections from optical pulses forwarded to a receiver. The profile is stored at the transmitter. Periodically during operation, such as during key exchange, more optical pulses are forwarded to the receiver, and the back reflections are collected as periodic profiles. The periodic profiles are compared against the stored profiles. Eavesdroppers, such as those who cut the fiber, tap the fiber, or implement a man in the middle attack, may be easily identified because the losses caused by their interference with the fiber will be evident in the periodic profiles.

Abstract: A system, device, and method for managing alternate site switching in an optical communication system recovers from failures/degradations that are uncorrected by the core optical communication network. When an uncorrected failure/degradation is detected, communications for a protected end-system are switched from a primary end-system to a backup end-system. The backup end-system may be selected a priori, for example, during connection establishment, in order to reduce switching time once a decision has been made to switch communications from the primary end-system to the backup end-system. Provisions are made for completing the alternate site switching within a specified amount of time. Load balancing may be used to further reduce switching time from the primary end-system to the backup end-system. This alternate site switching augments the various protection mechanisms provided by the core optical communication network in order to provide end-to-end protection for the optical communication path.

Abstract: A network image fusion service is provided that is configured to receive a plurality of image data and to execute at least one image fusion processes in both software and hardware. The image fusion process logic has been divided between instructions to be executed in software and logic to be executed in hardware. The software instructions may be executed by a processor within the network element or in a processor associated with network service. The hardware logic is executed in a reconfigurable programmable logic device such as an FPGA. The network service may be included within the network element, be separate from a network element but associated therewith, or may be external to the network and accessible by a plurality of network elements.

Abstract: A system, device, and method for managing service level agreements in an optical communication system uses an optical service agent to manage a service level agreement (SLA) for a user. The optical service agent can perform both real-time and off-line analysis for the user, and can interact with various network elements (including the core optical communication network) to handle billing, penalty, and other issues associated with a SLA breach.

Abstract: A method and apparatus has been shown and described which allows Quality of Service to be controlled at a temporal granularity. Time-value curves, generated for each task, ensure that mission resources are utilized in a manner which optimizes mission performance.

Abstract: A method and architecture of the present invention uses market-driven resource selection and mission deployment techniques to increase mission performance by optimizing network resource utilization. A mission controller forwards a service tender to a plurality of coupled network service entities to inquire about the costs associated with one or more services in the service set of the mission. Each network service entity may return a bid to the mission controller including a projected cost for the performance of the one or more services by the associated network service entity. The mission controller evaluates the bids received from the network service entities to select a network service entity for mission execution. Network resources selection is thus optimized using real-time network service entity cost information, thereby increasing the chance for mission success. Network service entities may increase revenue by identifying opportunities to participate in missions suited to their capabilities.

Abstract: A closed loop system is described for enhanced adaptive network capabilities in support of workflow missions. Multiple workflow-locked loops with different sampling rates are employed. A faster, lower loop is employed to gather data from the field and deal with network level exceptions such as faults, fades, and changing conditions. A slower, upper loop is employed to handle mission level exceptions. The result is a system capable of integrating management of multiple workflow missions, including reallocation of resources in response to changes in mission goal statements and network resource availability.

Abstract: A system, device, and method for managing connection establishment and related services in an optical communication system uses an optical service agent to manage the connection establishment and related services on behalf of a user. The optical service agent may negotiate various connection and connection-related services, model connections, reserve communication services, establish connections on behalf of the user, and aggregate multiple optical communication paths over a connection, to name but a few. The optical service agent may interact with an optical communication network and/or various peer users in order to obtain and reserve communication services.

Abstract: An optical switch router performs both optical switching and traditional routing. The optical switch router includes optical interfaces for coupling to one or more incoming optical fibers and to one or more outgoing optical fibers, and also includes a number of traditional router ports. Individual incoming optical data streams received over the incoming optical fiber(s) can be selectively passed through to one or more of the outgoing optical fibers or “dropped” from the optical communication path for traditional routing. Routed traffic, which can be received over the router ports or from the “dropped” optical data streams, can be forwarded over optical data streams that are “added” to the outgoing optical fiber(s). The “added” optical data streams may be added to the outgoing optical fiber(s) at any unused wavelengths, including, but not limited to, the wavelengths of the “dropped” optical data streams.

Abstract: A mechanism and framework is disclosed for translating high level goal statements to policy rules. In a first step, high level goal statements are translated to network services. In a second step, the network services are translated to network parameters. In a third step, the network parameters are translated to policy rules. The first step may be facilitated with Web Ontology Language (“OWL”) and semantic templates. Advantages of automated mission goal statement to policy statement translation for surveillance missions include more reliable and faster planning and allocation of resources in support of the missions. Further, dynamic allocation of network resources facilitates adapting to changing conditions and more graceful degradation in adverse circumstances. The need for subject matter experts is also expected to be mitigated.

Abstract: A system and apparatus for dropping and adding optical data streams in an optical communication network uses a photonic switching fabric for dropping but not adding optical data streams, and uses a combiner external to this photonic switching fabric for combining passed optical data streams from the photonic switching fabric together with added optical data streams. The added optical data streams are not limited to the wavelengths of the dropped optical data streams. The photonic switching fabric may be a Micro Electro Mechanical System (MEMS) that uses single-sided mirrors configurable to drop but not add optical data streams.

Abstract: A method and apparatus for providing network based load balancing of medical image data among two or more image archive systems is disclosed. A network element is employed to interface to a network carrying medical image data that may include tasks to be performed on the data. A network service associated with the network element monitors the current load or the available capacity of each of the image archive systems. When a task is received the network service determines the level of complexity of the task and compares the level of complexity to the current load or available capacity of each of the image archive systems. The network service selects the one of the image archive systems to perform the task that has the lowest current load or highest available capacity relative to the level of complexity of the received task.

Abstract: A method and apparatus for extracting information from a medical image data and transferring the extracted information in a separate format from the medical image data is disclosed. A network element is employed to monitor a network for medical image data transmitted on a network. The network element monitors the data packets on the data network to identify and retrieve the data packets containing medical image data. The medical image is reconstructed and the network element identifies and extracts desired information from within the medical image data. The network element then compresses the medical image data, and separately formats the extracted information from the medical image data. The medical image data and the extracted information are then transmitted to the image archive system via the network.
