摘要： 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.

摘要： 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.

A network interface includes a port, a de-multiplexer coupled to an output or the port, and prioritized receive queues that each have an MTTU size. A first prioritized receive queue has an MTU size different than a second prioritized receive queue.
