The Ethernet packet processing functions may comprise packet inspection, packet generation, and packet modification. The energy efficient Ethernet (EEE) processing may comprise generating and/or inspecting messages for controlling when to transition into and out-of an energy-saving mode. The Ethernet PHY may be operable to monitor signals and/or conditions within the Ethernet PHY and control transitions into and out-of an energy-saving mode based on the monitored signals and/or conditions. The energy saving mode may comprise a low power idle mode and/or a subset PHY mode.

A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In a computing environment made up of one or more personal computing devices (PCD) and/or one or more powered devices (PD), power source equipment (PSE) determines an allocated amount of power to be supplied to each device. The personal computing devices include a unified LAN-On-Motherboard (LOM) that combines the functionality of a powered device (PD) controller of a conventional PD and a LOM of a conventional personal computing device into a single unified subsystem. The unified LOM includes a standard or universal interface between the LOM and PD controller so that different types of PD devices with differing functionality can be easily married to the LOM, without requiring significant hardware or software redesign. The universal or standard interface includes a physical interface between the LOM and the PD controller and a compatible communication protocol to govern the communications between the LOM and the PD controller. This allows the LOM to be mixed and matched with any PD controller, enabling OEMs to economically provide multiple product models with varying degrees of PD and LOM functionality.

摘要:
A system and method for using a physical layer device to locate a thermal signature in a cable plant for diagnostic, enhanced, and higher power applications. Cable heating in specific sections of a network cable is detected through an automatic identification of a thermal signature in electrical measurements of a network cable. The correlation of the thermal signature to a specific section of the network cable enables network personnel to locate hot spots in the network cable with ease.

A Power-over-Ethernet (PoE) communication system dynamically provides power and data communications over a communications link. In an enterprise environment made up of one or more personal computing devices (e.g., personal or laptop computers), a switch determines a power classification for each device via a PoE control module that can be part of, for example, a Power Source Equipment/Powered Device (PSE/PD) system or a LAN-On-Motherboard/Powered Device (LOM/PD) system. A method of classifying power for each device includes detecting a device, polling it for power requirement information using a Layer 2 data link layer, receiving power requirement information from the device, and determining a power classification for the device. Power requirement information can include battery charge status, power load, power mode, etc., of the device. Various types of data packets can be used. The method can be repeated on a periodic basis, allowing power classification to be dynamic.

摘要:
An access device receives content from a broadband IP network to be communicated to a wireless handset over a radio access network (RAN). The access device acquires a user profile utilized in the radio network for the wireless handset. Based on the acquired user profile, the access device determines transmission parameters utilized for communicating the received content to the wireless handset using an air interface protocol over the radio access network. A security level and/or a security protocol, a transcoding mechanism, and/or transmission bit rate are determined based on the acquired user profile. A resolution, transmission bit rate, coding structure, security protocol and/or security level for transmitting the received content to the wireless handset are adjusted based on the acquired user profile. Alternately, the access device is enabled to receive content from the wireless handset using a transmission profile determined based on user profile of the wireless handset.
