    摘要: A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. When a sub-switch receives a multicast data frame, it forwards the packet to one of the surrogate sub-switches. Each surrogate sub-switch may then forward the packet to another surrogate in a different hierarchical level or to a destination computing device. Because the surrogates may transmit the data frame in parallel using two or more connection interfaces, the bandwidth used to forward the multicast packet increases for each surrogate used.

    摘要: A distributed switch may include a plurality of sub-switches. These sub-switches may be arranged in a hierarchy that increases the available bandwidth for transmitting multicast data frames across the switch fabric. Moreover, the distributed switch may be compatible with link aggregation where multiple physical connections are grouped together to create an aggregated (logical) link. Link aggregation requires similar data frames to use the same data path when traversing the distributed switch. With a unicast data frame, the sub-switch in the distributed switch that receives the data frame typically identifies the destination port (during a process called link selection) and forwards the data frame to the sub-switch containing that port. However, with multicast data frames, instead of the receiving sub-switch performing link selection to determine the destination port, link selection may be done by a different sub-switch or not done at all.

    摘要: A distributed switch may include a hierarchy with one or more levels of surrogate sub-switches (and surrogate bridge elements) that enable the distributed switch to scale bandwidth based on the size of the membership of a multicast group. Moreover, each surrogate may optimize the hierarchy according to one or more optimization criteria. For example, each surrogate in the hierarchy may have the necessary information to ensure that if the next surrogate in the hierarchy is unavailable, the data may be routed to a backup surrogate. The selected hierarchy may be further optimized by skipping surrogates (or a surrogate level) such that the data intended for a skipped surrogate is sent to a surrogate in a lower-level of the hierarchy. This may better utilize the connection interfaces in the transmitting sub-switches and eliminate any unnecessary surrogate-to-surrogate transfers.

    摘要翻译: 分布式交换机可以包括多个子交换机。 这些子交换机可以以层次结构来布置,从而增加跨越交换结构传输多播数据帧的可用带宽。 此外,分布式交换机可以与链路聚合兼容,其中多个物理连接被分组在一起以创建聚合(逻辑)链路。 链路聚合需要相似的数据帧才能在穿过分布式交换机时使用相同的数据路径。 通过单播数据帧,接收数据帧的分布式交换机中的子交换机通常标识目的端口(在称为链路选择的过程中),并将数据帧转发到包含该端口的子交换机。 然而,使用组播数据帧,代替执行链路选择的接收子交换机来确定目的地端口,链路选择可以由不同的子交换机完成,或者根本不完成。
