摘要： Various implementations disclosed herein enable a more efficient allocation of one or more shared network resources amongst a plurality of client devices based on media content complexity and client device resource status in order to better manage perceptual playback quality. In some implementations, a method includes obtaining a plurality of resource constraint values associated with a plurality of client devices sharing a network resource, and jointly determining a respective encoding rate level selection and a corresponding resource allocation for each of the plurality of client devices based on a combination of one or more resource constraint values and the assessment of the respective perceptual quality level values, such that a combination of resulting quality levels satisfies a joint quality criterion.

摘要： INTERNATIONAL SEARCH REPORT International application No. PCT/US05/ 18304 Box IV TEXT OF THE ABSTRACT (Continuation of Item 5 of the first sheet) A modular cable modem termination system (CMTS) (14) includes a packet shelf (16) operating a data over cable service interface specifications (DOCSIS) media access control (MAC) framer (22). One or more downstream physical interface (PHY) shelves (30) receive DOCKS data from the packet shelf (16) over a packet switched network (26) and modulate the DOCKS data for sending on a downstream path of a cable plant. One or more upstream PHY shelves (32) send DOCKS data received from an upstream path of the cable plant over the packet switched network (26) to the packet shelf (16). By separating the PHY components from the MACE and from the system software, the PHY components for a hybrid fiber coax (HFC) plant may be replaced with different PHY components for other access technologies such as wireless, digital subscriber lines (DSL), ethemet-to-the-home, fiber-to-the -home, or fiber passive optical networks (PONs).

摘要： Various implementations disclosed herein enable client devices to share a network resource in order to produce more evenly distributed perceptual playback quality levels within each subscription tier. Sharing of a network resource is facilitated by providing client devices with one or more QoE distribution indicator values, which enables client device participation in the allocation of the network resource. In some implementations, a client device method includes determining a local QoE level value, and then modifying a representation selection of media content data based on the local QoE and one or more QoE distribution indicator values. The local QoE level value characterizes perceptual playback quality of media content data received by the client device using the shared network resource. The QoE distribution indicator values characterize at least in part the relative QoE values associated with a plurality of client devices sharing the shared network resource with the client device.

摘要： Previously known network management methods are incapable of concertedly managing respective levels of perceptual playback quality of media content data for a number client devices. In particular, previously known methods fail to regulate ABR-enabled client devices and the like that are each operating to individually consume as much of one or more shared network resources as possible without regard to the degree performance improvements. By contrast, various implementations disclosed herein provide network-centric concerted management of respective levels of perceptual playback quality of media content data on each of a number of client devices. The respective levels perceptual playback quality are concertedly managed by adjusting one or more shared network resources (e.g., bandwidth, processor time, memory, etc.). Adjustments are made in response to an aggregate quality of experience (QoE) metric characterizing a distribution of QoE levels for the client devices sharing the one or more shared network resources.

摘要： Previously known network management practices fail to inform network operators about client-side performance and experience issues. By contrast, various implementations disclosed herein include systems, methods and apparatuses that generate one or more shared- resource traffic quality indicator values. Each shared-resource traffic quality indicator value characterizes at least a portion of the network by assessing a number of network performance characterization values in relation to one or more capacity values of one or more shared network resources. Each network performance characterization values provides a corresponding quantitative characterization of a quality of experience associated with the use of media content data received by a respective client device. In some implementations, quality of experience is characterized by at least one of an indication of perceptual quality of media content data and an indication of continuity with which media content data is used by a respective client device at a particular subscription tier.

摘要： Techniques are provided for enabling multicast traffic for a Cable Modem Termination System (CMTS) Modular Headend Architecture (MHA) system. The techniques allow a single modular CMTS core Media Access Control (MAC) domain to service a plurality of physical layer devices. When combined with an independent control plane, Downstream External physical layer (PHY) Interface (DEPI), and Upstream External physical layer (PHY) Interface (UEPI), a downstream PHY device becomes a completely independent and scalable network element.
