    • Methods to emulate a message signaled interrupt (MSI) with interrupt data are described herein. An embodiment of the invention includes a memory decoder to monitor a predetermined memory block allocated to a device, an interrupt controller to receive an emulated messaged signaled interrupt (MSI) signal from the memory decoder in response to a posted write transaction to the predetermined memory block initiated from the device, and an execution unit to execute an interrupt service routine (ISR) associated with the device to service the MSI using interrupt data retrieved from the predetermined memory block, without having to obtain the interrupt data from the device via an input output (IO) transaction.
    • 这里描述了用中断数据模拟消息信号中断(MSI)的方法。 本发明的实施例包括:存储器解码器,用于监视分配给设备的预定存储块;中断控制器,用于响应于向所述预定存储器块发布的写入事务,从所述存储器解码器接收模拟的消息发信号中断(MSI)信号 以及执行单元,用于执行与所述设备相关联的中断服务程序(ISR),以使用从所述预定存储器块检索的中断数据来服务所述MSI,而不必经由输入输出从所述设备获得所述中断数据 (IO)交易。

    • An embodiment may include determining at least one respective amount of buffer memory to be used to store at least one respective portion of network traffic. The determining may be based at least in part upon at least one respective parameter associated with the at least one respective network traffic portion. The at least one respective amount may be sufficient to store the at least one respective portion of the network traffic. The at least one respective parameter may reflect at least one actual characteristic of the at least one respective portion of the network traffic. This embodiment also may permit at least one respective portion of the buffer memory that may correspond to the at least one respective amount to be selectively powered-on to permit the at least one portion of the buffer memory to be used to store the at least one respective network traffic portion.

    • Methods and apparatus relating to network routing protocols to support power savings in network elements. A most utilized link path network topology for a computer network is discovered using a routing protocol such as a Spanning Tree, link-state, or distance vector routing protocol. In view of the most utilized link path network topology, links are identified as candidates for power management under which a power state of the link and associated network ports are managed to save power under applicable link conditions, such as low utilization. Link power-state change conditions are detected, and in response a corresponding change to the power state of a link is effected by changing the power-state of the network ports at the ends of the link. Power state changes include putting a link into a reduced power state, taking a link offline, and powering a link back up.
    • 与网络路由协议相关的方法和设备,以支持网元的节电。 使用诸如生成树,链路状态或距离矢量路由协议的路由协议来发现用于计算机网络的最有效的链路路径网络拓扑。 鉴于最广泛使用的链路路径网络拓扑,链路被识别为用于电力管理的候选,在该电源管理下,链路和相关联的网络端口的电力状态被管理以在诸如低利用率的适用链路条件下节省功率。 检测到链路功率状态改变状况,并且作为响应,通过改变链路端的网络端口的功率状态来实现对链路的功率状态的相应改变。 电源状态改变包括将链路置于降低功率状态,使链路脱机,并为链路供电。
