    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: Aspects of a method and system for implementing redundancy for streaming data in audio video bridging networks are provided. Network resources may be reserved over a plurality of network paths. Reserved resources may be utilized for the transmission and/or reception of a corresponding plurality of data streams, wherein one or more of the streams may comprise redundant data. A plurality of data streams may be transmitted and/or received by a plurality of network interface hardware devices. Similarly, a plurality of data streams may be transmitted and/or received by a plurality of ports integrated into a single network interface hardware device. Each of the plurality of data streams may be assigned a unique identifier and the identifier of a first data stream may differ by one bit from an identifier of a data stream comprising data redundant to the first data stream.

    摘要: Aspects of a method and system for determining and securing proximity information over a network are provided. In this regard, data transmitted over a network may be time-stamped upon entering and/or exiting a network node. By taking the total time to travel between two network nodes and subtracting out any latency internal to one or more intermediate nodes, the time to traverse the physical links (the propagation time) between the two network nodes may be determined. Accordingly, if the speed at which data propagates over each link of the network is known, then a distance from the source node to the destination node may be determined. Additionally, aspects of the invention may enable one or more of authentication, validation, and encryption of timing and/or proximity information transmitted over a network.

    摘要: A gateway network device may establish secure connections to a plurality of remote network devices using tunneling protocols to distribute to the remote network devices multimedia content received from one or more content providers. The consumption of the multimedia content may originally be restricted to local network associated with the gateway network device. The secure connections may be set up using L2TP protocol, and the L2TP tunneling connections may be secured using IPSec protocol. Use of multimedia content may be restricted based on DRM policies of the content provider. DRM policies may be implemented using DTCP protocol, which may restrict use of the multimedia content based on roundtrip times and/or IP subnetting. Each content provider may use one or more VLAN identifiers during communication of the multimedia content to the gateway network device, and the gateway network device may associate an additional VLAN identifier with each secure connection.

    摘要: 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.
