Abstract: Various embodiments allow Grid applications to access resources shared in communication network domains. Grid Proxy Architecture for Network Resources (GPAN) bridges Grid services serving user applications and network services controlling network devices through proxy functions. At times, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources. In some cases, resource-based XML messaging can be employed for the GPAN proxy communication.

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: A Grid Proxy Architecture for Network Resources (GPAN) is proposed to allow Grid applications to access resources shared in communication network domains. GPAN bridges Grid services serving user applications and network services controlling network devices through its proxy functions such as resource data and management proxies. Working with Grid resource index and broker services, GPAN employs distributed network service peers (NSP) in network domains to discover, negotiate and allocate network resources such as bandwidth for Grid applications. An elected master NSP is the unique Grid node that runs GPAN and represents the whole network to share network resources to Grids without Grid involvement of network devices. GPAN provides the Grid Proxy service (GPS) to interface with Grid services and applications, and the Grid Delegation service (GDS) to interface with network services to utilize network resources.

Abstract: Described are a method and a sensor aware network for dynamic processing of sensor data. Network context data are inserted into data packets from sensors or local sensor networks coupled to the sensor aware network. Sensor aware nodes in the sensor aware network can read the context data and can respond by performing specific network actions. The sensor data and network context data are provided to one or more application nodes. The sensor data and network context data can be stored in a database and later searched according to the network context data. Advantageously, sensor data flows can be treated differently by the sensor aware network, the application and the user, depending on the type of sensor data and the actual data values. Thus critical responses to certain sensor data flows can be implemented more efficiently than otherwise possible using conventional network configurations.

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: 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 method and apparatus for monitoring the transportation of medical images on a communication network includes a medical image transport service (MITS) that may be used to notify clients of the status of scheduled requests. The MITS may be configured to provide numerous notifications, such as the scheduled time for delivery, changes in scheduled time for delivery, delays associated with delivery at the scheduled time, and likely resolutions to network or other delays attendant to the requested transaction. The notifications may be sent in-band on the network or out-of-band on a parallel network. Where the notification relates to a delayed transaction, the notification message may contain the reason for the delay, the source of the delay, its location, and if other images can still be retrieved. The notification may also include a likely resolution of the problem and an estimate of when the problem will be resolved.

Abstract: A method and apparatus for facilitating the transportation of medical images on a communication network includes a medical image transport service (MITS) that may be used to set policy associated with the delivery of medical images on the network. The MITS may be configured to schedule transactions in an equitable manner taking into account the relative priority of the various contending medical image transactions and mediate delivery of images associated with the transactions. The MITS may include a data management service configured to interact with clients to handle transfers on the network, and a network resource manager configured to interface with network devices performing the transport services to enable network resources such as routes, paths, and bandwidth, to be reserved on the network. An administration client enables policy to be set on the MITS to enable operation of the transport service to be controlled.

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 scalable network architecture adapted to interface with various sensor types and sensor access mechanisms while providing real-time access to sensor data for distributed applications and organizations is described. A centralized sensor network service manages the registration, capabilities, near real-time status of the sensors and their current network connections. New sensors are discovered automatically through messaging between network access nodes and the sensor registry. The registry service can be made available to distributed sensor applications and sensor middleware, and facilitates the sharing of sensors across organizations. The sensor registry is automatically updated by network software and does not require manual configuration or reconfiguration each time a sensor is added to or relocated within the network. Authentication and authorization policies can be implemented to ensure that only authorized applications can query and view the registry.
