Abstract: Systems, devices, and automated processes optimize bandwidth utilization in wireless network systems such as satellite systems, 5G and other cellular networks, and wireless local area networks with multiple distribution nodes. Redundant unicasts of media streams are replaced by multicasts that can be transmitted by a subset of the available distribution nodes. This allows customer devices to receive redundant content over shared bandwidth that is available to the particular customer devices requiring access to the redundant content. Subsets of distribution nodes can be selected for transmitting multi-casts, thereby further reducing the amount of system bandwidth needed to provide high-quality media streams to multiple customer devices operating within the wireless network system.

Abstract: A method for estimating bandwidth associated with an oscillating network includes determining a set of first average bandwidths within a corresponding set of first sliding windows, wherein each of the first sliding windows has a first duration. A second sliding window is defined such that it includes the set of first sliding windows, the second sliding window having a second duration that is larger than the first duration. The system then determines whether a bandwidth oscillation (as illustrated) is occurring based on the first set of first average bandwidths within the second sliding window.

Abstract: A method and apparatus for providing a fault-tolerant backup system such that if there is a failure of a primary processing system, a replicated system can take over without interruption. The invention provides a software solution for providing a backup system. Two servers are provided, a primary and secondary server. The two servers are connected via a communications channel. The servers have associated with them an operating system. The present invention divides this operating system into two "engines." An I/O engine is responsible for handling and receiving all data and asynchronous events on the system. The I/O engine controls and interfaces with physical devices and device drivers. The operating system (OS) engine is used to operate on data received from the I/O engine. All events or data which can change the state of the operating system are channeled through the I/O engine and converted to a message format.
