An apparatus, system, and method are disclosed to failover to a standby server when a primary server is under broadcast storm or denial-of-service ('DoS') attack. A primary attack sensing module is included to monitor a rate of incoming data from a computer network to a primary server and to determine if the rate of incoming data is above a primary data rate threshold. A standby contact module is included to request a standby data rate status from a standby server in response to the primary attack module determining that the rate of incoming data to the primary server is above the primary data rate threshold. The standby server is connected to the primary server over a private network. The standby data rate status includes a determination by the standby server of whether a rate of data received by the standby server is above a standby data rate threshold. A standby receiver module is included to receive a standby data rate status from the standby server over the private network. A switchover module is included to deactivate the primary server and to send a command to activate the standby server as a primary server in response to the received standby data rate status indicating that the rate of data received by the standby server has not exceeded the standby data rate threshold.

Apparatus, system, and method for server failover to standby server during broadcast storm or denial-of-service attack

A computing system is provided with real-time capabilities so that the system is capable of running applications such that one or more real-time criteria are satisfied. An interrupt architecture of the computing system is disabled. The interrupt architecture generates interrupts sent to a firmware of the computing system in response to events. A different architecture is substituted within the computing system for the interrupt architecture. The different architecture is responsive to the events without violating the real-time criteria. In response to the events occurring, the different architecture causes one or more corrective actions to be performed.

Providing a computing system with real-time capabilities

Embodiments of the present invention address deficiencies of the art in respect to video scaling and compression and provide a novel and non-obvious method, system and computer program product for pre-distribution image scaling for screen size. In one embodiment of the invention, a compressed video delivery method can be provided. The method can include determining a display size for a target computing platform, pre-scaling video imagery to comport with the display size of the target computing platform, compressing the pre-scaled video imagery, and transmitting the compressed, pre-scaled video imagery to the target computing platform over a computer communications network.
