摘要： An approach is provided in which a virtual function, which executes on a network adapter, receives a data packet from a first virtual machine. A translation entry is identified that corresponds to sending the data packet from the first virtual machine to a second virtual machine, and a determination is made as to whether an onboard memory partition assigned to the virtual function includes the identified translation. If the onboard memory location includes the translation entry, the data packet is sent to the destination virtual machine using the translation entry retrieved from the onboard memory partition. Otherwise, if the translation entry is not located in the onboard memory partition, the data packet is sent to the destination virtual machine using a translation entry retrieved from an off board memory location.

摘要： Network adapter use of an interface specific buffer is managed so that their combined use with non-interface specific buffers has a reduced impact, such as when an interface specific buffer becomes full. If an attempt fails by a protocol stack of an operating system to buffer information for a packet in an interface specific buffer, an offset marks the end of the use of the interface specific buffer for the packet and a non-interface specific buffer is used to store the remaining information for the packet. During transmission of the packet, the offset is read by a network adapter driver to take advantage of reduced processing for sending information from the interface specific buffer and to identify information that need additional processing for transmission from the non-interface specific buffer.

摘要： Generally speaking, systems, methods and media for facilitating user-specified delivery options for e-mail messages are disclosed. Embodiments of the method may include receiving by an e-mail client an indication of contents of an e-mail message and a plurality of intended recipients of the e-mail message and generating the e-mail message based on the received indication. Embodiments may also include receiving an indication of user-specified delivery options for each intended recipient of the message, generating meta-data based on the user-specified delivery options, and adding an indication of the meta-data to the message, such as in the data area of the e-mail message. Embodiments may also include transmitting the e-mail message to a mail server. The user-specified delivery options may include one or more of attachment delivery options, signed copy recipient options, signature options, message importance options, return receipt options, delivery priority options, prevent copy recipient options, or message formatting options.

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.

摘要： A computer implemented method and apparatus are provided for transferring data in a logical partitioned data processing system. A receiving adapter receives data from a network. The receiving adapter transfers the data to a pre-mapped buffer if the data is to be sent to a target adapter. A virtual bridge receives the pre-mapped buffer from the receiving adapter and transfers the pre-mapped buffer to the target adapter. The target adapter receives the pre-mapped buffer from the virtual bridge and determines that the received buffer is pre-mapped. The target adapter accesses the pre-mapped buffer using pre-mapped mapping, and transmits the data contained therein.

摘要： A computer implemented method, apparatus, and computer usable program code for managing buffers. A number of buffers present in a pool of buffers assigned to a network device driver are monitored, wherein the buffers in the pool of buffers are used to process packets of data for transmission onto a network. A request is denied from a transport layer for a buffer from the pool of buffers if the number of buffers falls below a threshold level, wherein at least one buffer is present in a buffer pool if the number of buffers falls below the threshold level.
