Abstract: Configuring virtual machines for garbage collection in a deduplication backup system executed on a server computer in a cloud computing network, by configuring at least one virtual machine (VM) of a plurality of virtual machines in a VM cluster to be data protection virtual machines (DP VMs), by enabling only read and write operations to/from the DP VMs, interconnecting a garbage collection VM (GC VM) of the VM cluster to the DP VMs, configuring the GC VM to perform only garbage collection tasks for the DP VMs, and providing data access credentials from each DP VM to the GC VM to facilitate the garbage collection tasks.

Abstract: Embodiments for systems and methods of resetting network devices for failover operation, by receiving an operating system panic function call, disabling error reporting for all device ports of a device to be reset to prevent primary interrupts to a disk dump operation, performing a function level reset of the all the device ports to be reset, and performing the reset operation on the device in a single thread context to prevent secondary interrupts to the disk dump process.

Abstract: An adaptive predictive playout scheme, based on a Least Mean Square (LMS) prediction algorithm, for packet voice applications. The packets are received and stored in a buffer for playout at a constant draining rate P0, where P0 is determined by the codec used. The latency of the packets in the buffer is controlled by discarding the oldest packet in the buffer when the predicted time interval for receipt of the next incoming packet is less than a draining threshold.
