    摘要: 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.

    摘要: Certain aspects of a method and system for minimum frame size support for a communication protocol encapsulated over Ethernet may include an encapsulated protocol over Ethernet (EPoE) frame comprising a start of padding (SP) field. In the EPoE frame, a size of an encapsulated protocol frame that is less than a size of an Ethernet frame may be adjusted by insertion of one or more padding bits so that the size of the encapsulated protocol frame is equal to the size of the Ethernet frame. The SP field may indicate a starting location of the insertion of one or more padding bits within the EPoE frame. The SP field comprises an offset value that may be relative to a location of a word in which the SP field is located or is relative to a location of a word corresponding to a fixed offset from a start of the encapsulated protocol frame.

    摘要: Ethernet network link partners may be configured for operation in a low power mode. The link partners may generate new frames and/or signals and/or may modify characteristics of existing frames and/or signals to be communicated via one or more channels of an Ethernet link during the low power mode. The new and/or modified frames and/or signals may be utilized as refresh frames and/or signals to control communication during low power mode and/or to enable refresh and/or synchronization of the link partners. The new and/or modified frames and/or signals may be generated and/or modified based on a desired frequency distribution and/or spectral density. New and/or modified frames and/or signals may comprise jitter, random and/or pseudo random bit patterns and/or varied bit patterns and/or energy levels. Data packets and/or active idle symbols may be forced during low power mode to mitigate undesired periodic energy.

    摘要: A local manager in a local networking domain may configure a plurality of logical switches by combining switching functions available in network devices and/or network switches in the local networking domain. The configuration may utilize vertical and/or horizontal combinations of the switching functions. The switching functions may comprise network switch-based switching functions, and/or hypervisor-level switching functions and/or network adapter-level switching functions available in network devices which may be configured as virtualized platforms. The local manager may provide interfacing services to enable exposing configured logical switches. The interfacing services may comprise an internal interface, which may be utilized, via the local manager, to control the switching functions corresponding to logical switches and/or to route messages sent to and/or from the logical switches. The interfacing services may also comprise an external interface, which may be used by external entities, such as remote management entities, to manage and/or interact with configured logical switches.

    摘要: An Ethernet link may comprise a plurality of active and/or silent channels. Training of one or more link partners for one or more silent channels may be triggered based on monitoring training parameters for an active channel. The link partners may be trained for the silent channels and link partners corresponding to the silent channels may be configured according to the training. Training parameters for an active channel may be compared to a threshold or relative change value. The threshold or relative change value may be fixed, may be based on measurement results and/or may be programmable. The link partners may be configured for silent channels for an echo canceller, a far-end crosstalk canceller and/or a near-end crosstalk canceller. The silent channels may be trained based on transmitting a pulse or LDPC frame via the silent channels.

    摘要: Aspects of a method and system for programmable data rate thresholds for configurable data rate via inter-packet gap adjustment to support energy efficient networks. In this regard, an inter-packet gap may be adjusted to control a data rate on an Ethernet link. An IPG may be adjusted such that a data rate on a network link may be communicated at a non-standardized rate suited to an audio and/or video stream. An IPG may be adjusted such that data is communicated over the link at a standardized rate. In this regard, adjusting the IPG may compensate for a non-standardized data rate resulting from altering other parameters of the link. The IPG may be adjusted based on a control policy which may govern data rates on a network link. Each of a plurality of inter-packet gaps may be differently adjusted to achieve a desired average data rate on the link.

The one or more servers may be operable to directly communicate and/or receive packets to/from the FC switches via the network switch. The network switch may be operable to determine a destination address of one or more servers based on the facilitated proxy login by the CPU if the one or more servers utilize fabric provided MAC addresses (FPMA) or utilize a MAC address table if the one or more servers utilize server provided MAC addresses (SPMA).
