摘要： Methods, apparatus, and systems for implementing in Network Interface Controller (NIC) flow switching. Switching operations are effected via hardware-based forwarding mechanisms in apparatus such as NICs in a manner that does not employ use of computer system processor resources and is transparent to operating systems hosted by such computer systems. The forwarding mechanisms are configured to move or copy Media Access Control (MAC) frame data between receive (Rx) and transmit (Tx) queues associated with different NIC ports that may be on the same NIC or separate NICs. The hardware-based switching operations effect forwarding of MAC frames between NIC ports using memory operations, thus reducing external network traffic, internal interconnect traffic, and processor workload associated with packet processing.

摘要翻译： 在网络接口控制器（NIC）流切换中实现的方法，设备和系统。 切换操作通过诸如NIC的设备中的基于硬件的转发机制以不使用计算机系统处理器资源的方式实现，并且对由这样的计算机系统托管的操作系统是透明的。 转发机制被配置为在与可能在同一NIC或单独NIC上的不同NIC端口相关联的接收（Rx）和发送（Tx）队列之间移动或复制媒体访问控制（MAC）帧数据。 基于硬件的交换操作通过存储器操作来影响NIC端口之间的MAC帧的转发，从而减少与分组处理相关联的外部网络流量，内部互连流量和处理器工作量。
