    摘要: While transmitting a first Ethernet frame from the first buffer onto an Ethernet link, a first Ethernet device may stop transmitting the first frame prior to completing transmission of the frame. The first Ethernet device may then transmit a second frame from a second buffer onto the Ethernet link. The first Ethernet device may resume transmission of the first frame from the first buffer onto the Ethernet link. A second Ethernet device may receive, via the Ethernet link, a first portion of a first Ethernet frame and store the first portion of the first Ethernet frame in a first buffer. The second Ethernet device may then receive, via the Ethernet link, a second Ethernet frame and store the second Ethernet frame in a second buffer. The second Ethernet device may then receive, via the Ethernet link, a second portion of the first Ethernet frame and append it to the contents of the first buffer.

    摘要: Various aspects of a method and system for low-latency networking are provided. Latency requirements of traffic to be communicated along a network path comprising one or more Ethernet links may be determined. A maximum size of Ethernet frames utilized for communicating the traffic may be determined based on the latency requirements. The maximum size of the Ethernet frames may be determined based on a data rate of one or more Ethernet links along the network path. A single device may utilize different maximum packet sizes for different ports/links on which it communicates. One or more messages indicating the determined maximum size may be communicated among devices along the network path to coordinate maximum packet sizes.

    摘要: A first network device may select a plurality of network paths for establishing a plurality of network connections to a second network device. The selection may be based on support of IEEE Audio Video Bridging (AVB) protocols. The first network device may establish at least one of the plurality of connections over each of the selected network paths. The first network device may concurrently transmit and/or receive a plurality of data streams via the established plurality of network connections. At least a second one of the plurality of data streams may comprise data that is redundant to a first one of the plurality of data streams. One of the plurality of network connections may be selected for conveying a primary data stream based on determined path costs of the plurality of network paths, where non-AVB links may be assigned higher path costs than AVB link.
