Embodiment Construction

[0038] Certain embodiments of the present invention relate to methods and systems for implementing adaptive dynamic power reduction mechanisms for network devices in packet data networks. In various embodiments of the invention, the physical layer (PHY) in a network device may provide adaptive power reduction based on monitoring activity associated with an interface (between the PHY of the network device and the remaining components). Based on the monitoring, power management operations of the PHY may be configured and / or adjusted. The PHYs include Ethernet PHYs for supporting Energy Efficient Ethernet (EEE) functions. The monitored interface includes a Media Independent Interface (MII) based interface. Where said monitored activity includes outbound traffic, when at least one subcomponent of said PHY used to support transmission of said outbound traffic is idle due to power management operations, may buffer through an interface Received outbound data to be sent. The buffer...

Abstract

A physical layer (PHY) in a network device may provide self-adapting power reduction based on monitoring of activity associated with an interface between the PHY and remaining components of the network device. The power management operations of the PHY may then be configured and / or adjusted based on that monitoring. The PHY may comprise an Ethernet PHY, which may support energy efficient Ethernet (EEE) features. The monitored interface may comprise a Media Independent Interface (MII) based interface. In instances where the monitored activity comprises outbound traffic, outbound data received via the interface may be buffered when at least one subcomponent of the PHY that is operable to support transmission of the outbound traffic is unavailable due to the power management operations. The buffering may be configured to last to allow sufficient time to reactivate the at least one subcomponent.

Description

technical field [0001] The present invention relates to network connections. More specifically, the present invention relates to methods and systems for implementing adaptive dynamic power reduction mechanisms for physical layer devices in packet data networks. Background technique [0002] With the increasing popularity of electronic products such as desktop computers, laptops, and handheld devices such as smartphones and personal digital assistants, communication networks, especially Ethernet, are becoming increasingly important for exchanging data of various types and sizes in various applications. popular means. Based on this, Ethernet is increasingly used to transmit, for example, voice, data and multimedia. In this regard, there is an increasing reliance on networks and related protocols, such as Ethernet for the transmission of real-time and / or high-quality content and / or information. However, the transmission of such time-sensitive information places a severe burd...
