Abstract: Systems, devices, software, hardware and networks adapted and arranged for monitoring and correcting faults in networked media player systems that include electronic displays are provided. After detection or notification of a fault in at least one networked media player in a network of at least two, or N, media players operationally connected to electronic displays, the invention provides an alternate source of signal to the affected display. In some preferred embodiments, the invention utilizes at least one additional, or N+1, media player as a backup to substitute for the failed media player. Reconfiguration of the faulted media player by means of the N+1 backup networked media player advantageously increases the reliability and efficiency of ongoing maintenance of digital visual systems operating in commercial and other environments.

Abstract: A method and system are provided for automatically rerouting logical circuit data in a virtual private network (“VPN”). A dedicated logical circuit in the VPN is monitored for status information pertinent to the dedicated logical circuit. The dedicated logical circuit includes a primary communication path for communicating data. Based on the status information, a failure is identified in the dedicated logical circuit. Once the failure in the dedicated logical circuit is determined, a logical failover circuit is then identified. The logical failover circuit includes an alternate communication path for communicating the data for the failed dedicated logical circuit. After the logical failover circuit has been identified, the data from the dedicated failed logical circuit is rerouted to the logical failover circuit without manual intervention. After the data has been rerouted the logical failover circuit, a determination may be made as to whether the failure in the dedicated logical circuit has been corrected. If it is determined that the failure in the dedicated logical circuit has been corrected, then the data from the logical failover circuit is rerouted back to the dedicated logical circuit in the VPN without manual intervention.

Abstract: A method and system are provided for tracking the rerouting of logical circuit data in a data network. A disclosed example method involves updating reroute information in response to a dropped packet associated with a quality of service parameter having been exceeded. Transmitted data is rerouted to at least one logical failover circuit in the data network from at least one failed logical circuit associated with the exceeded quality of service parameter. The at least one logical failover circuit is selected based on a bit rate capability specified to be one of a committed bit rate, a variable bit rate, or an unspecified bit rate.

Abstract: Embodiments of a routing system are disclosed, including a method for routing communications in a storage system. The storage system may include multiple nodes interconnected by an interconnection fabric that provides multiple independent paths between a source node and a destination node. Some nodes may be connected to one or more disk drives. The method may include receiving a communication to be sent from a source node to a destination node, selecting a communication path from the multiple independent paths, and sending the communication on the selected communication path. This process may be repeated so that multiple communications may be sent. Each communication path may be selected according to a preference assigned to it, so that a more preferred path is selected more often than a less preferred path. The preferences may be updated to reflect changed conditions in the interconnection fabric.

Abstract: A fault tolerant transmission device and method for information processing systems. The fault tolerant transmission device utilizes a connecting system to connect to a SCSI bus. Along with the use of the disclosed fault tolerant transmission method of the server, the device manages information transmission of independent systems. When the independent system has errors and is unable to transmit information, the connecting system of the fault tolerant transmission device assigns the information transmission job to a normal independent system and notifies the user, so that the information processing system can still function normally when some independent systems have errors.
