Aspects of a method and system for managing an energy efficient network utilizing Audio Video Bridging are provided. In this regard, an Audio Video Bridging timeslot may be designated for handling an energy efficient networking (EEN) transaction and the EEN transaction may be performed during the designated timeslot. Exemplary EEN transactions comprise scheduling a data rate transition, transitioning to a different data rate, training a link partner, and exchanging training related information. It may be determined whether the timeslot may be reserved for conveying an AVB stream prior to designating the time slot for an EEN transaction. In instances that the timeslot may be unreserved, the timeslot may be reserved for EEN transaction(s). Information exchanged during the designated timeslot may enable scheduling a data rate transition and / or training on a network link. In this regard, a subsequent timeslot may be designated for the data rate transition and / or the training.

Communication devices may determine routes for packets based on packet marking, routing parameters and / or costs associated with routes. A route may be selected and the packets may be communicated via the selected route. The parameters may comprise service class, real time compression, packet preemption, quality measurements, tier bypass and / or power usage information. The costs may comprise capacity, efficiency and / or performance information for power usage, bandwidth, memory and / or processing. The marking may comprise traffic type, user device capabilities, service class, quality measurements, latency requirements and / or power usage information. Endpoint devices, software applications and / or service providers may insert the marking into packets. Routes may be determined and / or selected based on shortest path bridging, audio video bridging, the marking, the routing parameters and / or the costs. Parameters and / or costs may be received and / or discovered from communication devices. Packets and / or the marking may be parsed and / or inspected. Costs may be based on routing parameters.

Aspects of a method and system for implementing redundancy for streaming data in audio video bridging networks are provided. Network resources may be reserved over a plurality of network paths. Reserved resources may be utilized for the transmission and / or reception of a corresponding plurality of data streams, wherein one or more of the streams may comprise redundant data. A plurality of data streams may be transmitted and / or received by a plurality of network interface hardware devices. Similarly, a plurality of data streams may be transmitted and / or received by a plurality of ports integrated into a single network interface hardware device. Each of the plurality of data streams may be assigned a unique identifier and the identifier of a first data stream may differ by one bit from an identifier of a data stream comprising data redundant to the first data stream.

A method for providing time synchronization in a node connected to an Audio Video Bridging (AVB) Ethernet communication network includes steps of receiving static announcement messages from adjacent nodes and constituting a static grandmaster table, reselecting a grandmaster with reference to the static grandmaster table when a synchronization message timer expires, and updating the static grandmaster table according to reselection of the grandmaster. The method may rapidly time synchronization in the Audio Video Bridging (AVB) Ethernet communication network and minimize network load.

Aspects of a method and system for timely delivery of multimedia content via a femtocell are provided. In this regard, a femtocell may receive data via an upstream path and transmit data via a downstream path. One of the upstream path and downstream path may comprise a cellular path and the other may comprise a non-cellular path. One or both of the upstream path and the downstream path may be audio video bridging (AVB) paths. Data may be stored in the femtocell based on timing characteristics of one or both of the upstream path and the downstream path. Data may be delivered to the femtocell utilizing best effort delivery and the data may be forwarded by the femtocell with guaranteed quality of service. Resources in the femtocell may be reserved and / or synchronized, utilizing AVB protocols, for communication of one or more data streams.

An adapter or bridging device that provides both a wired audio or audio and video female jack connectors for wired devices such as wired earphones, headphones and wired video headsets; as well as a wireless link to nearby handheld computerized devices such as mobile phones (e.g. smartphones). The device may be configured to be clipped to the user's clothing, as well as to interface with pairing control devices to easily form Bluetooth, WiFi, or other type wireless links. The device may also include at least one computer processor to manage the wireless link, control the attached wired headphones or video headsets, as well as perform compression and decompression functions as desired.

Provided are a network system supporting a spanning tree protocol (STP), a relay apparatus thereof, and a method of creating a spanning tree. Proposed is a method of creating a tree topology, between AVB bridges, using a STP message including a group MAC address which is different from that used in a non-AVB (Audio Video Bridging) bridge (that is, a bridge without the function of AVB), in order to form a minimum number of AVB clouds. Therefore, it is possible to efficiently ensure transmission quality of a multimedia stream such as an AVB stream.

In a network having one or more Audio Video Bridging (AVB) devices, non-AVB bridges are detected by transmitting a maintenance message, such as a unicast linktrace message, from one AVB device such as a residential gateway to another AVB device such as a set-top box or IPTV. AVB devices in the path provide replies indicating whether the port on which the linktrace message was received is connected to a non-AVB bridge. The disclosure has utility in diagnostics problems with IPTV in a network.

An operation method of a communication node in a vehicle network is disclosed. A transmission method performed by a communication node may be configured to comprise performing an initialization operation for transmission of an audio video bridging (AVB) stream, performing an operation of obtaining a buffer for the transmission of the AVB stream, performing the transmission of the AVB stream stored in the buffer, and performing an operation of finalizing the transmission of the AVB stream. Accordingly, performance of the vehicle network can be enhanced.
