摘要: A network switch that has a plurality of input ports that receive data packets. An external interface is connected to the plurality of input ports. The external interface externally transmits the data packets for processing, and receives the data packets after processing. A memory management unit is connected to the external interface and a plurality of output ports are connected to the memory management unit.

摘要: A method of forwarding data in a network switch fabric is disclosed. An incoming data packet is received at a first port of the fabric and a first packet portion, less than a full packet length, is read to determine particular packet information, the particular packet information including a source address and a destination address. An egress port bitmap is determined based on a lookup in a forwarding table and it is determined if the destination address belongs to a trunk group of trunked ports. The incoming data packet is forwarded based on the egress port bitmap, when the destination address does not belong to the trunk group. When the destination address does belong to the trunk group, a particular trunked port of the trunk group is determined and the incoming data packet is forwarded thereto. More specifically, the particular trunked port of the trunk group may be determined by calculating a hash value based on the source address and the destination value and selecting the particular trunked port based on the hash value. Additionally, a class of service for the incoming data packet is also determined from the particular packet information and a priority for forwarding is set based on the class of service.

摘要翻译: 公开了一种在网络交换结构中转发数据的方法。 在结构的第一端口处接收输入数据分组,并且读取小于全分组长度的第一分组部分以确定特定分组信息,所述特定分组信息包括源地址和目的地地址。 基于转发表中的查找来确定出口端口位图,并且确定目的地址是否属于中继端口的中继线群组。 输入的数据包根据出口端口位图转发,当目的地址不属于中继线群组时。 当目的地址属于中继组时,确定中继组的特定中继端口,并将传入的数据包转发到其中。 更具体地,可以通过基于源地址和目的地值计算哈希值并基于哈希值来选择特定中继端口来确定中继线群组的特定中继端口。 此外,还根据特定分组信息确定用于输入数据分组的一类服务,并且基于服务等级设置用于转发的优先级。
