摘要： A multi-stage network is provided, where the network includes a first stage comprising a first plurality of network switching devices, the first plurality of network devices being classified into switching groups. The network further includes a second stage comprising a second plurality of network switching devices. A linking configuration, comprising a plurality of links between the first plurality of network switching devices and the second plurality of network switching devices, couples the first stage to the second stage. Each first stage network switching device in a given switching group includes the same number of links to any given second stage network switching device as each other first stage network switching device in that group.

摘要： A system and method provides for delivering substantially uniform performance to all hosts in a network while minimizing a total number of switches required to deliver that performance. In a multi-stage network having a plurality of switches in a first tier and a plurality of switches in a second tier, additional switches may be deployed in the second tier to alleviate problems occurring as a result of uneven striping. A minimum number of second tier switches to be deployed may be determined as a function of a target level of throughput, for example, when using WCMP flow distribution.

摘要： An initial rule set in a table, such as a packet forwarding table, including a plurality of rules each having a key, an action, and a priority, may be reduced to a reduced rule set. Such reduction may include identifying relationships among the plurality of rules in the initial rule set, reassigning priority to each rule in the initial rule set based on its action and the identified relationships, duplicating all rules from each priority into each lower priority to produce an expanded rule set, and for each priority, replacing one or more of the rules with fewer inclusive rules, thereby producing a reduced rule set. Reduction may further include determining whether to perform additional rule processing on the reduced rule set, removing any redundant rules from the reduced rule set, converting any of the rules meeting a predetermined condition into don't care rules, and for each priority, replacing one or more of the rules in the reduced rule set with fewer inclusive rules.

摘要： The present technology considers network devices that include forwarding tables having a number of next-hop entries (e.g., egress ports) where it is possible that the egress port utilization can be load balanced using WCMP groups. In a WCMP group, its members are assigned weights representing an amount of data flow to distribute over a plurality of links for a given destination. This disclosure provides systems and methods to distribute weights assigned to members of WCMP groups while achieving a minimum target for network throughput.

摘要： The present technology considers multi-stage network topologies where it is not possible to evenly stripe uplinks from a lower stage of the network topology to switching units in an upper stage of the topology. This technology proposes techniques to both improve overall throughput and to deliver uniform performance to all end hosts with uneven connectivity among the different stages while delivering uniform performance to all hosts. To achieve improved network performance in case of asymmetric connectivity, more flows may be sent to some egress ports than to others, thus weighting some ports more than others, resulting in Weighted Cost Multi Path (WCMP) flow distribution.

摘要翻译： 本技术考虑到多级网络拓扑，其中不可能均匀地将上行链路从网络拓扑的较低级别划分到拓扑的上级中的交换单元。 该技术提出了提高总体吞吐量并为所有终端主机提供统一性能的技术，不同阶段之间的连接不均衡，同时为所有主机提供均匀的性能。 为了在不对称连接的情况下实现改进的网络性能，可以向某些出口端口发送比其他端口更多的流，因此比其他端口更多地加权一些端口，导致加权成本多径（WCMP）流分布。
