Abstract: Systems and methods provide network address failover capability within an application gateway device. In one aspect, a system has a first network interface and a second network interface. The system receives a set of configuration data, the configuration data may include a first network address for the first network interface and a second network address for the second network interface. At startup or during later operation, the system may detect the failure of the first network interface. The configuration data may be analyzed to determine if the first network address can be used on the second network interface. If so, the first network address is moved from the first network interface to the second network interface.

Abstract: An OPC redirection manager maintains the information necessary for taking appropriate action when the target OPC server fails and for ensuring that no bad status is returned to the client. Any existing OPC client needing seamless failover between target OPC data access and/or alarm and event servers will connect to a uniquely configured instance of the redirection manager instead of connecting to the primary server. The client application continues to perform OPC related tasks as usual. Because each client connection is unique, the redirection manager itself is not a single point of failure. Each configured redirection manager instance monitors the health of the target server mode and the target server itself by subscribing to failure events.

Abstract: For the benefit of a reference ISP having a number of users, connectivity evaluations on a data communication network are performed relative to one or more ISPs of interest.

Abstract: A method and system for streaming media data to a mobile client device. Using information such as the previous locations of the mobile client device, a prediction is made of a future location of the client device. A server servicing the predicted location, such as the server closest to the predicted location, is identified. This server is informed of the impending arrival of the mobile device into the area serviced by the server. The server can thus obtain ahead of time the media stream needed for the client, so that the data are available to the client without disruption when the client moves to the predicted location. To account for uncertainty in the prediction, the data can also be directed to other servers that can service the predicted location.

Abstract: A method and system for monitoring, controlling and diagnosing operation of a machine such as a business office machine including a facsimile machine, a copier, and a printer.

Abstract: In the face of data loss on connections between a content source and a content consumer, additional connections therebetween are opened. These additional connections are preferably opened between the content source and a proxy disposed between the content source and the content consumer. The proxy may then seam together data streams received from the content source across the additional connections in a recording on a computer-readable medium. The seamed stream may be constructed by filling in information gaps in any of the data streams received from the content source with content derived from others of the data streams received from the content source. This derivation may be made on the basis of identifying characteristics (e.g., packet contents) of packets from each of the data streams received from the content source.

Based on a determination that the second device is unavailable to receive the response packet, a second router receives the response packet. After determining that the second router was not in the outbound path, the second router forwards the response packet to the firewall if the firewall is available or to the first router if the first firewall is unavailable and the first router is available.

Abstract: Session independent end to end route control is provided by coordination between a pair of route control devices. Each device determines whether received traffic qualifies for end to end route control and whether the device at the other end supports end to end route control. If so, then the route control devices determine a routing mode, such as tunneling or address translation, and routing parameters. The performance of the selected path is monitored and is changed if the performance becomes unacceptable. Path performance can be measured using one-way measurement techniques that use a common inbound path or a control channel.

Abstract: Network flows are identified by analyzing network traffic and network host information. The network host information may be collected by network host monitors associated with network hosts. Network traffic and network host information are evaluated against network flow profiles to identify network flows. If a network flows are identified with high certainty and are associated with previously identified network applications, then network flow policies can be applied to the network flows to block, throttle, accelerate, enhance, or transform the network flows. If a network flow is identified with lesser certainty or is not associated with a previously identified network application, then a new network flow profile can be created from further analysis of network traffic information, network host information, and possibly additional network host information collected to enhance the analysis.
