    • Aspects of a method and system for implementing energy efficient Ethernet techniques in a MACSec enabled PHY are provided. In this regard, an Ethernet PHY comprising memory may be operable to perform packet processing functions comprising MACSec protocol processing and energy efficient Ethernet (EEE) processing. In this regard, the memory may be utilized for implementing the MACSec protocol processing and energy efficient Ethernet (EEE) processing. 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 distributed address database management technique involves maintaining an address database by each of a number of interconnected modules. Each module maintains a number of locally owned address entries and a number of remotely owned address entries in the address database. Each module monitors the status of its locally owned address entries, maintains the locally owned address entries based upon the status, and provides the status to the other interconnected modules. Each module maintains the remotely owned address entries based upon the status received from the other interconnected modules. When a module adds a locally owned address entry to its address database, the module notifies the other interconnected modules, which in turn add a corresponding remotely owned address entry to their respective address databases. When a module purges a locally owned address entry from its address database, the module notifies the other interconnected modules, which in turn purge the corresponding remotely owned address entries from their respective address databases. Each module may periodically send a keep-alive message including a list of active addresses to the other interconnected modules, which maintain a persistence timer for each of the remotely owned address entries and purge a particular remotely owned address entry if the corresponding persistence timer expires before receiving a keep-alive message identifying the remotely owned address entry as an active remotely owned address entry. Upon receiving a keep-alive message, a module adds a remotely owned address entry for a particular address to its address database if such a remotely owned address entry is not already maintained in the address database. A module purges all remotely owned address entries from its address database if the module is reconfigured to operate in a stand-alone mode. A module purges all remotely owned address entries associated with a particular interconnected module if that particular interconnected module is removed.

    • An arbitration unit contains a method of arbitration which includes distributed arbitration, a priority mechanism to support different classes of traffic, a unique arbitration ID bits for each module, a round robin arbitration within a given priority level to produce fair access to a bus 36, an arbitration timeout, and a bandwidth allocation between priority levels. The method of round robin bus arbitration includes the steps of providing a plurality of modules, providing a bus having a plurality of data lines, the bus connecting the plurality of modules, the bus having an arbitration unit, setting the bus to a wait state, signaling a first bus request to the bus by a first module needing to transmit a first plurality of data packets on to the bus, the first module having a first module priority level and a first unique arbitration number, signaling a second bus request to the bus by a second module needing to transmit a second plurality of data packets on to the bus, the second module having a second module priority level and a second unique arbitration number, establishing a bus priority according to a comparison of the first module priority level and the second module priority level, asserting the first unique arbitration number on the bus by the first module, asserting the second unique arbitration number on the bus by the second module, determining whether the first module and the second module have been waiting for the bus, comparing the first unique arbitration number and the second unique arbitration number, scheduling transmission of data packets in response to the steps of determining and comparing, and repeating the steps of setting, signaling, establishing, asserting, determining, comparing, and scheduling.
    • 仲裁单元包含一种仲裁方法，其包括分布式仲裁，支持不同类别的业务的优先级机制，每个模块的唯一仲裁ID比特，给定优先级别内的循环仲裁以产生对总线36的公平访问， 仲裁超时，以及优先级之间的带宽分配。 循环总线仲裁的方法包括提供多个模块的步骤，提供具有多个数据线的总线，连接多个模块的总线，总线具有仲裁单元，将总线设置为等待状态， 通过需要将第一多个数据分组发送到总线的第一模块向总线发出第一总线请求，第一模块具有第一模块优先级和第一唯一仲裁号，向总线发信号通知第二总线请求 通过需要将第二多个数据分组发送到总线的第二模块，第二模块具有第二模块优先级和第二唯一仲裁号，根据第一模块优先级和第二模块优先级的比较来建立总线优先级 第二模块优先级，由第一模块在总线上声明第一唯一仲裁号，由第二模块在总线上断言第二唯一仲裁号，阻止 挖掘第一模块和第二模块是否等待总线，比较第一唯一仲裁号和第二唯一仲裁号，响应于确定和比较的步骤调度数据包的传输，并重复设置步骤 ，信号，建立，断言，确定，比较和调度。
