Abstract: Certain example embodiments relate to the concept of controlling the flow of data by providing an intelligent flow controller/manager, and a client-side component for the selection of a communication channel from a pool, and having these components communicate to regulate data flow through gateways to a broker- and/or other-type secondary stage. Data fragmentation and reassembly can be used to increase performance, e.g., through self-regulating behaviors. Advantageously, reliability is improved by enabling in-memory data persistence, rather than resorting to potentially performance-degrading use of disk storage. The delivery mechanism may be used to deliver data to multiple consumers, providing an end-to-end sender-to-consumer solution that self-regulates to optimize the data flow while still being reliable.

For example, for AM write requests an AM write request handler may write data contained in an AM write request to a remote address space in memory on the remote node, or generate a corresponding RMA write request that is enqueued into an RMA queue used in accordance with a tagged message scheme. Similar operations are performed by AM read requests handlers. RMA reads and writes using AM are further facilitated through use of associated read, write, and RMA progress modules.

Abstract: The congestion notification system of some embodiments sends congestion notification messages from lower layer (e.g., closer to a network) components to higher layer (e.g., closer to a packet sender) components. When the higher layer components receive the congestion notification messages, the higher layer components reduce the sending rate of packets (in some cases the rate is reduced to zero) to allow the lower layer components to lower congestion (i.e., create more space in their queues by sending more data packets along the series of components). In some embodiments, the higher layer components resume full speed sending of packets after a threshold time elapses without further notification of congestion. In other embodiments, the higher layer components resume full speed sending of packets after receiving a message indicating reduced congestion in the lower layers.

Abstract: A method and apparatus for allocating bandwidth in a broadband wireless communication system is disclosed. One embodiment uses a self-correcting bandwidth request/grant protocol. The self-correcting bandwidth request/grant protocol utilizes a combination of incremental and aggregate bandwidth requests. CPEs primarily transmit incremental bandwidth requests to their associated base stations, followed by periodic transmissions of aggregate bandwidth requests. The use of periodic aggregate bandwidth requests (that express the current state of their respective connection queues) allows the bandwidth allocation method and apparatus to be “self-correcting”. Another embodiment utilizes an abridged bandwidth request/grant protocol to allocate bandwidth. The abridged bandwidth request/grant protocol system utilizes padding packets to request a reduction in bandwidth allocation to a CPE. A base station modem alerts a base station CPU when the BS modem receives a padding packet from a CPE.

Each of the video streams is classified as a rate adaptive stream or as a non-rate adaptive stream.

For video streams classified as non-rate adaptive streams, the video streams are assigned to a buffer queue for non-rate adaptive streams.

Abstract: An order controller stores each received event in a separate entry in one of at least two queues with a separate counter value set from an arrival order counter at the time of storage, wherein the arrival order counter is incremented after storage of each of the received events and on overflow the arrival order counter wraps back to zero. The order controller calculates an exclusive OR value of a first top bit of a first counter for a first queue from among the at least two queues and a second top bit of a second counter for a second queue from among the at least two queues. The order controller compares the exclusive OR value with a comparator bit to determine whether a first counter value in the first counter was stored before a second counter value in the second counter.

Abstract: A jitter buffer in a Voice over LTE receiver may be influenced by radio level feedback (RLF) from both local and remote endpoints to preemptively adjust the jitter buffer delay in anticipation of predicted future losses that have a high probability of occurring. The radio events of the RLF and the scenarios that trigger the preemptive adjustments may be identified, and their use may be expressed in terms of mathematical formulas. Previously, the instantaneous jitter was derived from a weighted history of the media stream, and consequently only packets that had already been received were used to compute the instantaneous jitter to adjust the length of the buffer. By providing and using RLF from both local and remote endpoints, the anticipated delay—for packets that have not yet arrived—may be used to preemptively adjust the buffer, thereby minimizing packet loss without introducing unnecessary delay.

Abstract: A distributed database management system provides a central database resident on a server that contains database objects. Objects, e.g., program guide data, to be replicated are gathered together into distribution packages called “slices,” that are transmitted to client devices. A slice is a subset of the central database which is relevant to clients within a specific domain, such as a geographic region, or under the footprint of a satellite transmitter. The viewer selects television programs and Web content from displayed sections of the program guide data which are recorded to a storage device. The program guide data are used to determine when to start and end recordings. Client devices periodically connect to the server using a phone line and upload information of interest which is combined with information uploaded from other client devices for statistical, operational, or viewing models.

Abstract: Some embodiments provide a method for reducing congestion in a network stack that includes a series of components that send data packets through the network stack to a network. At a first component of the network stack, the method receives a data packet from a second component of the network stack. The method identifies a usage indicator value for a flow to which the data packet belongs. The usage indicator value is based on a comparison of a size of the flow to a size of a queue for a third component of the network stack. The method determines whether to send the data packet based on a comparison of the usage indicator value to a threshold usage value. The method sends the data packet to a next component of the network stack only when the usage indicator value is less than the threshold usage value.

Abstract: Each of the nodes included in an ad-hoc network determines whether an identifier indicative of high-priority data is included in data received from another node. When the identifier is included in the received data, each of the nodes determines whether the subject node is a device that relays the received data to a destination. When determining that the subject node is a device that relays the received data to the destination, each of the nodes transmits the received data to the destination. When determining that the subject node is not a device that relays the received data to the destination, each of the nodes suppresses data transmission to the nodes included in the ad-hoc network.
