摘要： In an example embodiment, an apparatus comprising a physical layer processing device that comprises logic configured to process a packet received from a physical layer interface is disclosed. The physical layer processing device logic is further configured to determine a preamble portion of the packet and a data portion of the packet. The physical layer processing device logic is further configured to insert a timestamp into the preamble portion of the packet. The physical layer processing device logic forwards the packet with the timestamp inserted into the preamble.

摘要： In an example embodiment, there is disclosed herein logic encoded in at least one tangible media for execution and when executed operable to receive a packet. The logic determines a client associated with the packet. The client associated with a service set, and the service set associated with a transmitter. The logic determines a drop probability for the selected client determines a current packet arrival rate for the selected client and determines whether to enqueue or drop the packet based on the drop probability for the selected client and the current packet arrival rate associated with the selected client. The drop probability is based on a packet arrival rate and virtual queue length for the, which is based on a packet arrival rate and virtual queue length for the service set that is based on a packet arrival rate and virtual queue length for the transmitter.
摘要翻译：在一个示例性实施例中，本文公开了逻辑编码在至少一个有形介质中用于执行，并且当被执行时可操作以接收分组。逻辑确定与数据包相关联的客户端。与服务集相关联的客户端以及与发射机相关联的服务集合。该逻辑确定所选择的客户端的丢弃概率确定所选择的客户端的当前分组到达速率，并且基于所选客户端的丢弃概率以及与所选择的客户端相关联的当前分组到达速率，确定是否对分组进行入队或丢弃。丢弃概率基于分组到达速率和虚拟队列长度，其基于基于分组到达速率和发射机的虚拟队列长度的服务集合的分组到达速率和虚拟队列长度。

摘要： In an example embodiment, packets for a selected flow are replicated and sent over one or more diverse paths, such as a primary path and at least one secondary path, to a destination switching device. At the destination switching device, one copy of the replicated packets is selected for delivery to the destination, and the remaining copies are discarded. In the event that packets are not received at the destination switching device due to loss of connection on the primary path or packets are not timely delivered due to congestion on the primary path, a different path may be selected as the primary path.
摘要翻译：在示例实施例中，用于所选流的分组被复制并通过一个或多个不同路径（诸如主路径和至少一个次要路径）发送到目的地交换设备。在目的地交换设备处，选择复制的分组的一个副本以传送到目的地，并且剩余的副本被丢弃。如果由于主路径上的连接丢失而在目的地交换设备处没有接收到分组，否则由于主路径上的拥塞而不能及时地传送分组，可以选择不同的路径作为主要路径。

摘要： A system and method for selective flooding in a multicast network are disclosed. Some embodiments provide for a promiscuous mode device on a network to signal to one or more other devices on the network that the promiscuous mode device is operating in promiscuous mode. In response to such a signal, one or more devices on the network dynamically cease operating in non-broadcast mode and dynamically commence operating in broadcast mode to ensure that the promiscuous mode device sees all data transmissions on the network or sub-network.

Such logical ports allow for customer separation and may be created based on VLAN ID and MPLS labels. In one embodiment, each service provided via a packet forwarding device is associated with a unique logical port. The logical port may span multiple physical ports.
