    • An Ethernet device includes receive buffers and transmit buffers of a port, and a processor. The buffers are each associated with a respective class of service. The processor operates to determine a current buffer utilization in a receive buffer, determine that the current buffer utilization is different than a buffer threshold for the receive buffer, determine a data rate limit for the class of service associated with the receive buffer based upon the difference between the current buffer utilization and the buffer threshold, and send a data rate limit frame to another device coupled to the port. The data rate limit frame includes the data rate limit for the class of service.

    • An information handling system (IHS) includes a plurality of processors that include a cache memory, and a receive side scaling (RSS) indirection table with a plurality of pointers each pointing to a processor. A network data packet received by the IHS determines a pointer to a first processor. In response, information associated with the network data packet is transferred to the cache memory of the first processor, The IHS also includes a process scheduler that moves a process associated with the network data packet from a second processor to the first processor, and RSS module that directs the process scheduler to move the process and associates the first pointer with the processor in response to directing the process scheduler. In one embodiment, the processes are virtual machines so that network packets associated with a virtual machine are processed by sending an interrupt to a processor supporting executing the virtual machine.
    • 信息处理系统(IHS)包括多个处理器,其包括高速缓存存储器,以及具有指向处理器的多个指针的接收侧缩放(RSS)间接表。 由IHS接收的网络数据分组确定指向第一处理器的指针。 作为响应,与网络数据分组相关联的信息被传送到第一处理器的高速缓冲存储器。IHS还包括将与网络数据分组相关联的处理从第二处理器移动到第一处理器的进程调度器,以及RSS模块 指导进程调度程序移动进程,并响应于指导进程调度程序将第一指针与处理器相关联。 在一个实施例中,这些进程是虚拟机,使得通过向支持执行虚拟机的处理器发送中断来处理与虚拟机相关联的网络分组。
