Abstract: System and method for energy efficient Ethernet with asymmetric traffic profiles. A low power mode such as a low power idle mode is typically leveraged when both direction of a link do not have data traffic to transmit. Where only one direction of a link has data traffic to transmit, a physical layer device can transition from a full duplex mode to a simplex mode to produce energy savings (e.g., disabling cancellation circuitry).

Abstract: An energy efficient sleep signature in power over Ethernet. In one embodiment, a signature of a powered device is first detected. It is then determined whether the detected signature is indicative of an unknown powered device. In one example, a detected signature of an approximately 25 kΩ impedance is indicative of an unknown powered device. Where the detected signature is indicative of an unknown powered device a normal PoE startup powering process can be used that includes a conventional detection, classification and powering process. Where the detected signature is indicative of a powered device that was previously known to the PSE, then powering of the PD can proceed with a fast-restart powering method that retains previous powering parameters.

Abstract: A system for hierarchical management of devices may include memory and a processor. The processor may configure first devices of a first network with device operating policies to perform operations based at least on attributes of the first devices, where the operating policies prevent device interference. The processor may discover a second network of second devices managed by a second management entity and may negotiate with the second management entity to determine a primary management entity for the networks. The processor may receive device operating policies and attributes of the second devices when the second management entity is not the primary management entity. The processor may provide an adjusted device operating policy for a second device to the second management entity when the second device causes interference with a first device, the adjusted second device operating policy being based at least on attributes of the second device.

Abstract: In automotive networking applications, data about vehicle's environment can be used in conjunction with a control policy to manage the performance and power usage of a networked device. The control policy can dynamically adjust the balance between link power and performance of the device's communications interface by taking into account the vehicles current situation and user preferences, e.g. location, destination, speed, sensor status, or the like. Controlling the balance between link power and performance of networked devices can be important in maximizing power savings without unacceptably decreasing network performance.

Abstract: Aspects of a method and system for controlling data distribution via cellular communications with an integrated femtocell and set-top-box (IFSTB) device are provided. In this regard, a cellular enabled communication device may detect when it is within cellular communication range of a femtocell. Upon detection of the femtocell, the cellular enabled communication device may communicate instructions to a content source instructing the content source to deliver multimedia content to the femtocell. In instances that multimedia content is already being delivered to the cellular enabled communication device prior to the detection, the instructions from the cellular enabled communication device may instruct the content source to redirect the multimedia content to the femtocell. In this regard, the multimedia content may be delivered from the content source to the cellular enabled communication device via the femtocell. The femtocell may deliver at least a portion of the multimedia content to other communication devices.

Abstract: It may be determined via monitoring whether a first link partner and/or a second link partner coupled via an Ethernet link has trained or refreshed circuitry and/or has updated at least one parameter. Based on the determination, a corresponding link partner may be trained, refreshed and/or updated. One or more of an echo canceller, a far-end crosstalk canceller and a near-end crosstalk canceller for one or more channels may be configured based on the training, refreshing and/or updating. One or more channels may be silent and/or one or more may be active. Link partners may communicate via one or more of in-band signaling, out-of-band signaling to determine which link partner may monitor and/or which may control or initiate operation. The controlling link partner may be assigned a master mode of operation. Training, refreshing and/or updating for the monitoring link partner may be based on a timer.

Abstract: Training, refreshing and/or updating Ethernet link partners for silent channels and/or silent directions of channels may be determined based on control parameters. This may be used to improve energy efficiency in Ethernet communication. Control parameters may comprise a default value and/or may be determined based on prior training, refreshing and/or updating. New values for the control parameters may be generated based on a magnitude of change between current and prior control parameter values or based on performance such as bit error rate. User input may be utilized to determine when to execute the training, refreshing and/or updating. The training, refreshing and/or updating may be done for one or more of a near-end crosstalk canceller, alien near-end crosstalk canceller, far-end crosstalk canceller, alien far-end crosstalk canceller and echo canceller. After the training, refreshing and/or updating, the silent channels may transition to active and/or may remain silent.

Abstract: A proxy device for a network of devices may include memory, a device status module, a data intercept module, a network interface, and an emulation module. The memory may be configured to store an emulation policy for emulating a device in a network, where the policy includes a status criterion that indicates a status of the device for which the policy applies. The device status module may be configured to monitor the status of the device. The data intercept module may be configured to intercept action requests directed to the device. The network interface may be configured to forward the intercepted action requests to the device when the status of the device fails to satisfy the status criterion. The emulation module may be configured to emulate the device, and respond to the action request without accessing the device, when the status of the device satisfies the status criterion.

Abstract: A media converter to enable Ethernet in thin-profile mobile devices. The media converter can be designed to interface with a thin-profile mobile device via a short-reach Ethernet link and to interface with a network device via a conventional Ethernet link. Protocol conversion is therefore obviated, while accommodating a low-profile Ethernet port in the mobile device.
