    • Latency requirements for Ethernet link partners comprising PHY devices and memory buffers, may be determined for packets pending transmission. Transmission may be interrupted for a first packet having greater latency than a second packet, and the second packet may be transmitted. The second packet may be interrupted for transmission of a third or more packets. Packets are inspected for marks and/or for OSI layer 2 or higher OSI layer information to determine the latency requirements prior to completion of transmission of the first packet. The second packet is transmitted after a first portion of the first packet and/or prior to a second portion. Delimiters are inserted among the first and/or second packets for interrupting transmission. A PHY layer, MAC layer and/or higher OSI layer of the second link partner may receive, buffer and/or parse the packets and/or packet portions and/or may reconstruct the first packet and/or the second packet.
    • 可以为待发送的分组确定包括PHY设备和存储器缓冲器的以太网链路伙伴的延迟要求。 对于具有比第二分组更长的延迟的第一分组,传输可能被中断,并且可以发送第二分组。 第二个分组可能被中断以传输第三个或更多个分组。 检查分组的标记和/或OSI层2或更高的OSI层信息,以确定在完成第一分组的传输之前的等待时间要求。 第二分组在第一分组的第一部分之后和/或在第二分组之前被发送。 在第一和/或第二分组之间插入分隔符以中断传输。 第二链路伙伴的PHY层,MAC层和/或更高的OSI层可以接收,缓冲和/或解析分组和/或分组部分和/或可以重建第一分组和/或第二分组。

    • Communication devices may determine routes for packets based on packet marking, routing parameters and/or costs associated with routes. A route may be selected and the packets may be communicated via the selected route. The parameters may comprise service class, real time compression, packet preemption, quality measurements, tier bypass and/or power usage information. The costs may comprise capacity, efficiency and/or performance information for power usage, bandwidth, memory and/or processing. The marking may comprise traffic type, user device capabilities, service class, quality measurements, latency requirements and/or power usage information. Endpoint devices, software applications and/or service providers may insert the marking into packets. Routes may be determined and/or selected based on shortest path bridging, audio video bridging, the marking, the routing parameters and/or the costs. Parameters and/or costs may be received and/or discovered from communication devices. Packets and/or the marking may be parsed and/or inspected. Costs may be based on routing parameters.
    • 通信设备可以基于分组标记,路由参数和/或与路由相关联的成本来确定分组的路由。 可以选择路由,并且可以经由所选择的路由来传送分组。 这些参数可以包括服务类别,实时压缩,分组抢占,质量测量,层次旁路和/或功率使用信息。 成本可以包括用于功率使用,带宽,存储器和/或处理的容量,效率和/或性能信息。 标记可以包括业务类型,用户设备能力,服务类别,质量测量,延迟要求和/或功率使用信息。 端点设备,软件应用和/或服务提供商可以将标记插入分组。 可以基于最短路径桥接,音频视频桥接,标记,路由参数和/或成本来确定和/或选择路由。 可以从通信设备接收和/或发现参数和/或成本。 分组和/或标记可以被解析和/或检查。 成本可能基于路由参数。

    • Link partners coupled via an Ethernet link comprise memory buffers and/or PHY devices and the memory buffers may be operable to buffer packets that are pending delivery via the PHY devices. Latency requirements may be determined by inspecting OSI layer 2 or higher OSI layer information. Markings within packets may be inspected for latency requirements. An order of communicating buffered packets may be determined based on latency requirements. Corresponding packet headers may be ordered based on the latency requirements. Packet delivery may be scheduled based on the latency requirements. A specified time and/or a specified quantity of buffered data, which may be statically or dynamically programmable and/or configurable, may trigger determination of latency requirements. Packets may be delivered after an indication that prior packets have been delivered. Latency requirements may depend on a device that may generate and/or render the packets.
    • 通过以太网链路耦合的链路伙伴包括存储器缓冲器和/或PHY设备,并且存储器缓冲器可以用于缓冲正在通过PHY设备进行传送的分组。 延迟要求可以通过检查OSI层2或更高的OSI层信息来确定。 可能会检查数据包内的标记是否有延迟要求。 可以基于等待时间要求确定缓冲分组通信的顺序。 可以根据等待时间要求对相应的分组报头进行排序。 可以基于等待时间要求来安排分组传送。 可以静态或动态可编程和/或可配置的指定时间和/或指定数量的缓冲数据可以触发等待时间要求的确定。 可以在提供先前数据包的指示之后传送数据包。 延迟要求可能取决于可能生成和/或呈现数据包的设备。

    • Network Interface Controller (NIC) logic may receive a packet comprising a routing parameter indicating a service or cost to be utilized in processing the packet. The NIC logic may determine a selected virtual machine (VM) running on a network device to process the packet according to the routing parameter. The NIC logic may communicate the packet across a network after the packet has been processed by the selected virtual VM. Or, the NIC logic may initialize a VM in the network device to process the packet according to the routing parameter. The NIC logic may receive multiple packets and determine a second selected VM or initialize a second VM to process the multiple packets according to the respective routing parameters of the multiple packets. The routing parameters may indicate device capabilities, service class, quality measurements, latency, power usage or any combination thereof.
