摘要： Processing data packets from a receive queue is provided. It is determined whether packets are saved in a pre-fetched queue. In response to determining that packets are not saved in the pre-fetched queue, a number of packets within the receive queue is determined. In response to determining the number of packets within the receive queue, it is determined whether the number of packets within the receive queue is greater than a number of packets called for by an application. In response to determining that the number of packets within the receive queue is greater than the number of packets called for by the application, an excess number of packets that is above the number of packets called for by the application is saved in the pre-fetched queue. An indication is sent to the application of the excess number of packets. The predetermined number of packets is transferred to the application.

摘要： A mechanism is provided for providing resource affinity for multi-queue network adapters via dynamic reconfiguration. A device driver allocates an initial queue pair within a memory. The device driver determines whether workload of the data processing system has risen above a predetermined high threshold. Responsive to the workload rising above the predetermined high threshold, the device driver allocates and initializes an additional queue pair in the memory. The device driver programs a receive side scaling (RSS) mechanism in a network adapter to allow for dynamic insertion of an additional processing engine associated with the additional queue pair. The device driver enables transmit tuple hashing to the additional queue pair.

摘要： A method for selective link aggregation in a virtualized data processing environment is provided in the illustrative embodiments. A data packet is received at a switch. An identifier associated with the data packet is determined. The identifier corresponds to a logical partition in a logical partitioned data processing system. A lookup is performed in a data structure to determine a set of ports associated with the identifier. The set of ports is retrieved from the data structure. A port is selected from the set of ports and the data packet is transmitted from the port to the logical partition.

摘要： Mechanisms for providing a network adapter and functionality for performing link aggregation within a network adapter are provided. With these mechanisms, a network adapter is provided that includes a plurality of physical network ports for coupling to one or more switches of a data network and a link aggregation module, within the network adapter, and coupled to the plurality of physical network ports. The link aggregation module comprises logic for aggregating links associated with the plurality of physical network ports into a single virtual link. The link aggregation module interfaces with a virtual Ethernet bridge (VEB) of the network adapter to send data to the VEB and receive data from the VEB.

摘要： An approach is provided in which a data traffic module executing on a network interface card receives a data packet initiated by a first virtual machine with a destination at a second virtual machine. The data traffic module identifies one or more physical path translations corresponding to a logical connectivity that is independent of physical topology constraints of a physical network. In turn, the data traffic module encapsulates the data packet with the one or more physical path translations and sends the encapsulated data packet to the second virtual machine over the physical network.

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 system receives a notification at an operating system image of a change in allocation of queue pair resources to the operating system image. The system queries a physical network adapter through a hypervisor to obtain a new queue pair resource count that will exist in the virtualized system after the change in allocation. The system performs a hashing operation in the operating system image using the new queue pair resource count to distribute transmit traffic among the queue pair resources that will exist in the virtualized system after the change in allocation.

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： A method of dynamically changing an allocation of queue pair resources to an operating system image running in virtualized environment receives a notification at the operating system image of a change in allocation of queue pair resources to the operating system image. The method queries a physical network adapter through a hypervisor to obtain a new queue pair resource count that will exist in the virtualized system after the change in allocation. The method performs a hashing operation in the operating system image using the new queue pair resource count to distribute transmit traffic among the queue pair resources that will exist in the virtualized system after the change in allocation.
