Abstract: Aspects of a method and system for symmetric transmit and receive latencies in an energy efficient PHY are provided. In this regard, a delay introduced by a PHY of a network device for outbound traffic and a delay introduced by the PHY for inbound traffic may be controlled such that a transmit delay of the network device is equal, within a tolerance, to a receive latency of the network device. The delays may be controlled based on whether one or more energy efficiency features are enabled in the PHY. The delay introduced by the PHY for outbound traffic may be controlled based on an amount of buffered inbound traffic. The delay introduced by the PHY for inbound traffic may be controlled based on an amount of buffered outbound traffic. The delays may be controlled such that said receive latency and the transmit latency are approximately constant regardless of a mode of operation of the network device.

Abstract: Automotive area networks (AAN) have a substantially fixed network topology, meaning that the physical media used for communications between devices included in the AAN is known. For example, the physical connections within an AAN, sometimes provided by wiring harnesses, can include fixed lengths of twisted pairs of wire (“twisted pairs”). Pre-compensation parameters related to characteristics of the twisted pairs can be determined at the factory, and loaded into the memory of devices connected to the AAN. These pre-compensation parameters are used to improve the fast wake up and link acquisition times of connected devices. Various characteristics of the physical communication channel are measured or estimated as a function of mechanical, ingress, climactic, and environmental variations (MICE), and used to update the pre-compensation parameters.

Abstract: An environment, such as an industrial environment, may include a control network with multiple network devices. A network device in the control network may have groups of communication ports servicing upstream and/or downstream network traffic. The group of communication ports may have, for example, two communication ports. Transmission parameters of the communication ports may be dynamically configured based on a first network port configuration and a second network port configuration for the first and second communication ports, respectively. The first network port configuration may have different transmission parameters than the second network port configuration. The first network port may forward data packets over the control network according to the first network port configuration, while the second network port may forward data packets to the next hop device utilizing the second network port configuration.

Abstract: A system and method for enabling energy efficient Ethernet networks with time-sensitive protocols. Time-stamped packets generated by a time-sensitive protocol rely on fixed latency in a transit time through a transmission subsystem. An energy efficiency control policy in a network device governs a transmission of time-stamped packets in accordance with energy efficiency initiatives controlled by the energy efficiency control policy. In one embodiment, time-stamped packets can be dropped or modified to account for transitions by the transmission subsystem into an energy saving state. In another embodiment, transitions by the transmission subsystem into or out of an energy saving state can be impacted by the existence of time-stamped packets scheduled for transmission.
