    Abstract: This disclosure relates to offloading processing intensive tasks in communication protocol specific operations off the device, e.g. to another network node connected to the device via a network. Such tasks may for example include flow control, segmentation/desegmentation, and/or error control. As part of error control, protocols of the transport protocol layer of the OSI protocol stack may include checksum calculation to ensure reliability of the (payload) data. The calculation of checksums may be processing intensive. For this reason, example client nodes that realize the offloading of processing intensive tasks in communication protocol specific operations to another network node may not utilize any transport layer protocol at all, but rely on flow control and error control implemented in most modern data link layer protocols (Layer 2 of the OSI protocol stack). Accordingly, the processing intensive tasks can be “shifted” from the client device to another device.

    Abstract: A method and apparatus for offloading packet classification processing of an access point in a residential gateway. A residential gateway includes a wireless access point and a processing circuit. The processing circuit receives a data packet from a network via a network port, processes the data packet to obtain packet classification information for the data packet, and sends the data packet with the packet classification information to the access point. The access point may process the data packet based on the packet classification information received from the processing circuit. The packet classification information includes at least one of a basic service set identifier, a station identifier, and an access category. The processing circuit may include a packet accelerator. The packet accelerator may write a cookie including the packet classification information in a packet descriptor for the data packet.

    Abstract: Example methods, apparatus, systems and articles of manufacture (e.g., physical storage media) to control digital video bandwidth utilization with a virtualized communication hub are disclosed. Example methods disclosed herein include monitoring, with a virtual access function of the virtualized communication hub, an aggregate load on a broadband access medium to detect bandwidth utilization events. Disclosed example methods also include sending, from the virtual access function, a first notification message to a virtual set-top box of the virtualized communication hub in response to detecting a first bandwidth utilization event. Disclosed example methods further include adjusting, at the virtual set-top box and based on the first notification message, an output bandwidth for streaming digital media from the virtual set-top box to a physical set-top box via a broadband access medium.

    Abstract: Techniques are disclosed for controlling data transmission in multi-stream digital systems. The techniques disclosed allow an input stream to a conditional access system to be throttled when a FIFO begins to fill up. Each data stream may have its own FIFO, which sends data to a MUX and exports its status to a backpressure rate control module. Multiple seconds worth of data may be stored in a BPRC buffer ahead of the backpressure rate control module prior to being transmitted to a MUX FIFO buffer. The backpressure rate control module may use the cached data to fill available spaces within a MUX FIFO buffer. The determination to forward a data packet may be based on the individual MUX FIFO buffer levels, the sum of all the MUX FIFO buffer levels, and/or one or more configurable threshold values. In some embodiments, individual thresholds may be assigned to each FIFO buffer.

    Abstract translation: 公开了用于控制多流数字系统中的数据传输的技术。 当FIFO开始填充时,所公开的技术允许对条件访问系统的输入流进行限制。 每个数据流可以具有其自己的FIFO,其将数据发送到MUX并将其状态导出到背压速率控制模块。 在发送到MUX FIFO缓冲器之前,可将多秒数据的数据存储在背压速率控制模块之前的BPRC缓冲器中。 背压速率控制模块可以使用缓存的数据来填充MUX FIFO缓冲器内的可用空间。 转发数据分组的确定可以基于各个MUX FIFO缓冲器级别,所有MUX FIFO缓冲器级别的总和和/或一个或多个可配置的阈值。 在一些实施例中,可以将各个阈值分配给每个FIFO缓冲器。
