    摘要: Aspects of a method and system for traffic management via virtual machine migration include detecting an abnormal traffic pattern in traffic communicated by a first virtual machine that utilizes a first set of network resources. Responsive to the detection of the abnormal pattern, a second virtual machine that utilizes a second set of network resources may be initialized. The second virtual machine may take over functions performed by the first virtual machine and initialization of the second virtual machine is based on an analysis of the traffic. The second virtual machine may be initialized utilizing stored virtual machine state information in instances that the abnormal traffic is a result of a malicious attack. The second virtual machine may be initialized utilizing current virtual machine state information in instances that the abnormal traffic is not a result of a malicious attack.

    摘要: Aspects of a method and system for determination and exchange of network timing information are provided. In this regard, for each network hop traversed by a packet, a propagation delay of said network hop may be determined. Moreover, the propagation delay, and/or a hop length calculated utilizing the propagation delay, may be appended to the packet. The packet may, for example, be a MMRP registration packet or a SRP reservation packet. The packet may be dropped in instances that the propagation delay and/or length of a one or more traversed network hops is outside a determined range. The hop length may be determined by multiplying the propagation delay by a speed of propagation on the hop. The speed of propagation may be determined based on the physical layer technology associated with the network hop. Digital rights management may be implemented for media communicated on the network hop based at least in part on the hop length or the propagation delay. In this regard, use of media content may be restricted to a specified location.

    摘要: A virtual machine running on an endpoint device may encode a mark comprising routing parameters within one or more packets of a packet stream to indicate services and/or costs to be utilized in processing and/or communicating the packet stream. The virtual machine may communicate the packet stream to another network device. The routing parameters within the marks may indicate device capabilities, service class, quality measurements, latency and/or power usage. The routing parameters may comprise costs that may indicate capacity, efficiency and/or performance of power usage, bandwidth, absolute and/or relative latency, frame-drop eligibility, memory and processing. The packet stream is received and inspected to identify the marks and/or routing parameters. A virtual machine may be initialized and/or configured to process and/or communicate the packet stream based on the routing parameters. Routing may utilize based SPB, TRILL, and/or AVB.

    摘要: A network device comprising an asymmetric, multi-rate, Ethernet, optical MAC and an asymmetric, multi-rate, Ethernet, optical PHY, communicates optical signals via a network utilizing NV bridging services. Higher bandwidth NV optical signals are communicated and lower bandwidth optical signals are received and/or vice versa. Optical signals may be communicated based on a plurality of different single mode Ethernet optical protocols and/or different multimode Ethernet optical protocols. Optical signals may be communicated at 10 Gbps in one direction and at a lower rate in a reverse direction. Extended range mode may be utilized. PDUs comprise time stamps, traffic class designations and/or destination addresses. Data rate requests, resource reservation messages and/or registration for delivery of PDUs may be communicated. Time stamps enable end to end transport within a specified latency target. Video signals may be compressed, uncompressed, encrypted, unencrypted and/or formatted for a video display interface.
