摘要： Various systems, processes, and products may be used to filter multicast messages in virtual environments. In particular implementations, a system, process, and product for filtering multicast messages in virtual environments may include the ability to determine whether a multicast message has been received, examine a local filtering store for a match for the destination address of the multicast message, and send the message to a number of virtual machines if a match for the address is found. The system, process, and product may also include the ability to analyze a filtering store of at least one of the virtual machines for a match for the address if a match is not found in the local filtering store and send the message to a number of the virtual machines if a match for the address is found in a filtering store of one of the virtual machines.

摘要： A data processing system stack initializes a first mbuf chain limit to a pre-set level. It receives at least one packet. The system receives at least one packet. The system returns an mbuf data structure in response to receiving at least one packet from an IP address. The system measures a health of the network connection to determine whether the network connection satisfies a first health criterion. The system reduces the mbuf chain limit to a second mbuf chain limit, responsive to the health of the network connection not satisfying the first health criterion. The system measures the health of the network connection to determine whether the network connection meets a second health criterion.

摘要： In link aggregation configurations, a data packet may be copied into a buffer space of a first NIC. Load balancing techniques may determine that the packet should be transmitted by a second NIC. The packet exists in memory that the second NIC cannot access. The data packet is copied into memory accessible to the second NIC or the memory location of the packet is registered with the NIC. A copy penalty is incurred if a packet is copied from a first buffer space to a second buffer space. A registration penalty is incurred if the location within the first buffer space is registered with the second NIC. Functionality can be implemented within a link aggregation configuration to register buffer space shared among interconnected NICs. Sharing of buffer space between interconnected NICs allows any one of the NICs to access data within the shared buffer space without incurring a penalty.

摘要： The method determines whether a particular virtual adapter of a virtual network IHS may perform enhanced packet communication transfer of larger sizes than those of physical network IHSs. The method registers each virtual adapter maximum receive unit (MRU) value in an MRU attribute table within a hypervisor virtual switch. The hypervisor virtual switch provides communication pathways for packet transfers between virtual network IHS virtual adapters and also between physical adapters. The method determines if a sending virtual adapter is sending a packet to a receiving virtual adapter that is local or a remote virtual trunk adapter. The method determines if the receiving virtual adapter exhibits a registered MRU value. If the receiving virtual adapter exhibits a registered MRU value, the method provides for larger sizes of packet transfers for those particular packets.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to obtain buffers in a multiprocessor system. A software component receives a call from an I/O device driver for a buffer, the call including at least one parameter, and walks a bucket data structure to a current bucket. The software component then determines whether the current bucket is free, and obtains a buffer list contained with the current bucket. Responsive to a determination that the current bucket is free, the software component determines whether sufficient buffers are obtained based on the parameter. Upon determining there are sufficient buffers obtained, the software component provides the current bucket and a second bucket as a single buffer list to the I/O device driver.

摘要： Disclosed is a computer implemented method, computer program product, and apparatus to enqueue one or more packets in a device driver for an I/O adapter. A device driver receives, by a processor executing the device driver, a reference to a list of transmit packets. The device driver may then atomically fetch and set a transmit active flag, wherein atomically setting comprises determining a former status of the transmit active flag. Responsive to a determination that a former status of the transmit active flag is different than a current status of the transmit active flag, the device driver atomically removes, by a processor executing the device driver, any packets referenced by a host machine transmit queue reference. The device driver pre-pends transmit packets referenced by the host machine transmit queue reference to the list of transmit packets to form an augmented list of transmit packets. The device driver builds a work request based on the augmented list of transmit packets. The device driver notifies the I/O adapter of the work request. The device driver atomically resets the transmit active flag.
