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： 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： Where parallel links between network devices are aggregated into link groups to support the transport of associated data streams, the link groups can be managed in an energy efficient manner by defining each link group as consisting of a primary link and one or more secondary links. The primary link in a link group remains enabled at all times but the secondary links are enabled only when needed and are disabled when no longer needed, minimizing power consumption for the secondary links (and the link group).

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： A computer implemented method, computer product code, and data processing system are provided for transferring data between virtual partitions. A request is received to transfer a packet from a first partition to a second partition. A free buffer is identified from a buffer pool of the second partition, and a receive descriptor is written. A bit within the receive descriptor is set to identify a receive descriptor ring of second partition. A first interrupt is generated to the second partition. The packet is then copied to the free buffer, and the receive descriptor is updated.

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： The present invention provides a computer implemented method and apparatus for allocating communication buffers in a data processing system. The method comprises a streamlined mbuf pool service receiving a call from an I/O device driver, then determining if at least one mbuf linked list is empty. In response to a determination that at least one mbuf linked list is empty, the streamlined mbuf pool service calls an OS mbuf allocator to provide all mbufs in a second mbuf linked list, wherein the second mbuf linked list comprises a head of the second mbuf linked list. The streamlined mbuf pool service repopulates the second mbuf linked list, obtains a requested mbuf from the second mbuf linked list, and advances the head of the second mbuf linked list by at least one mbuf. The streamlined mbuf pool service then returns the requested mbuf to the I/O device driver, wherein the OS mbuf allocator allocates all mbufs in the second mbuf linked list.
