Abstract: A method for sharing data content is provided. The method includes aggregating requests to share data content across broadcast networks and re-broadcasting the data content based at least in part on the number of requests or a determined capacity of the broadcast networks.

Abstract: Automatically converting a synchronous data transfer to an asynchronous data transfer. Data to be transferred from a sender to a receiver is initiated using a synchronous data transfer protocol. Responsive to a determination that the data is to be sent asynchronously, the data transfer is automatically converted from the synchronous data transfer to the asynchronous data transfer.

Abstract: Requests from multiple users for one or more shared resources can be dynamically throttled based on at least one allowance value determined for each user at a current point in time. One or more business functions or other such algorithms can be used to determine an appropriate allowance value for a user based on any of a number of appropriate factors, such as the cost of a resource, a value of the user, a request volume of the user, or other such factors. The values for each user can be fed into one or more algorithms to determine information such as request limits, burst limits, and costs per request. Such approaches provide for dynamic and fine-grained traffic shaping while allowing for variance of these limits or values over time.

Abstract: A method for management of performance of computer systems and applications includes prompting the user to select information for monitoring, monitoring the performance of applications running on servers, displaying data, and prompting users to input performance adjustments. A user is prompted to select a server or server group, a resource, and a threshold or condition for notification, and in response a system compares the value or quality of the parameter to the threshold or condition, and provides a notification to the user in the event that the parameter reaches the threshold or condition. A method includes the steps of providing the user with performance information, receiving from the user a request for more specific performance information, and providing more detailed performance information.

The GUI interface preferably comprising widgets, enabling a subscriber to manage subscriptions to topics. The Pub/Sub service publishes messages of a topic according to the subscription list.

Abstract: The real-time aspects of keep-alive generation are removed from the dynamic routing protocol (DRP) application and are embedded within a Unix-based operating system, which is programmed by DRP. A keep-alive control provides the ability to create a keep-alive message and a timeout interval on a TCP socket. Each socket can have an independent keep-alive message and timeout interval. A keep-alive message is sent whenever the TCP socket sends no normal user output for a duration exceeding the timeout interval. A timeout interval is normally specified in seconds and a keep-alive message is user definable and must not exceed a predetermined length in bytes. System calls are used to set the timeout interval and keep-alive message independently. Both a timeout and a keep-alive message must be set before the timeout becomes active.

Abstract: Apparatus and methods are provided for delivering end-to-end Quality of Service (QoS) over Internet Protocol (IP) networks. According to one embodiment, a portion of available bandwidth between a first and second network device is reserved as a Quality of Service (QoS) resource pool for real-time communication sessions among users of a first and second user community. The first network device is communicatively coupled with a packet network and associated with the first user community. The second network device is communicatively coupled with the packet network and associated with the second user community.

Abstract: The Automated Data Delivery Systems (ADDS) are two delivery systems designed to either deliver specific data to customer computers over a network such as the Internet or from one application program to another application program. In both cases the user computer requesting data delivery can either have an automatic data reception capability or receive the data without screening the incoming data. In particular, ADDS are systems that allow data delivery services to be offered on the Internet or an Intranet between two Internet/Intranet sites (I2I) or a data delivery service to be offered between an Internet site and a User Computer (I2U). In addition the ADDS invention includes a modification to existing or future application programs that allow the program to deliver 1) specified data 2) in the format specified by the user 3) to the location specified by the user, and 4) at a schedule specified by the user.

Abstract: Electronic messages are published through a pub/sub service to subscribing clients. Client applications filter incoming messages according to user predefined criteria, only presenting messages to the user that pass filtering criteria. Messages are preferably Instant Messages transmitted in a SOAP protocol.

Abstract: A client subscribes to a pub/sub service, the client comprises an application program for performing an operation on a published message received from a Pub/Sub service. The operation on the message comprises any one of saving the message to storage, accessing a web service based on information in the received message, authorizing subscription, executing an application identified by the message, filtering the message information for presentation to a user, overriding a message function, transforming the message media format or forwarding the message to another node.

Abstract: Context-based routing in multi-hop networks involves using a context-based routing metric. In a described implementation, respective path values are calculated for respective ones of multiple paths using the context-based routing metric. A path is selected from the multiple paths responsive to the calculated path values. Data is transmitted over at least one link of the selected path. In an example embodiment, the context-based routing metric is ascertained responsive to an estimated service interval (ESI) of a bottleneck link of each path of the multiple paths. In another example embodiment, the context-based routing metric is ascertained responsive to an expected resource consumption (ERC) metric. In an example embodiment of path selection, the path is selected using a context-based path pruning (CPP) technique that involves maintaining multiple local contexts at each intermediate node, with each local context representing at least one partial path.

Abstract: The present invention is directed to an apparatus and associated method for the sharing and communication of video and other surveillance related multimedia data by streaming video and other data from an emergency response unit to a variety of devices and other emergency response units. Surveillance data obtained through a variety of monitoring options, including sources external to the first response unit is wirelessly disseminated from that first response patrol car or similar emergency response unit, to any number of other devices on a digital network.

Abstract: A method of optimizing data transmissions to a wireless device is provided. In particular, a client application may discover the data rate of the wireless connection, and provide that information to a media server. The media server may then provide content to the application over the wireless connection, where the level of media detail provided is best suited for transmission at the available data rate.

To accomplish this, each identity claim includes an assertion that specifies an identification string unique to a principal within the associated scheme. Exemplary schemes for an individual include email accounts, telephone numbers, credit card account numbers and social security numbers. Thus, exemplary identification strings for an individual are specific email addresses, specific telephone numbers, etc.
