Abstract: A number of improvements in network adapters that offload protocol processin g from the host processor are provided. Specifically, mechanisms for handling memory management and optimization within a system utilizing an offload network adapter are provided (730). The memory management mechanism (730) permits both buffered sending (1770) and receiving (1680) of data as well as zero-copy sending and receiving of data. In addition, the memory management mechanism (730) permits grouping of DMA buffers (1130) that can be shared among specified connections based on any number of attributes. The memory management mechanism (730) further permits partial send and receive buffer operation, delaying of DMA requests so that they may be communicated to the host system (710) in bulk, and expedited transfer of data to the host system (710).

Abstract: Ein System, ein Verfahren und ein Programmprodukt für die Standortwahl von Ladestationen. Ein Bewegungserkennungsmodul erfasst Verkehrsdaten von Fahrzeugsensoren, die in einem Bereich verteilt sind. Ein Kartenanpassungsmodul kartiert den erkannten Verkehr in dem Bereich. Ein Fahrzeugstrommodul charakterisiert den kartierten Verkehrsstrom in Abhängigkeit von der Zeit. Eine Auswerteeinrichtung für die Anforderungen (EVR) von Elektrofahrzeugen (EV) ermittelt die optimale Anzahl von Ladestationen und die entsprechenden Standorte für die Standortwahl der Ladestationen.

Abstract: A number of improvements in network adapters that offload protocol processing from the host processor are provided. Specifically, a mechanism for improving connection establishment in a system utilizing an offload network adapter is provided. The connection establishment mechanism provides the ability to offload connection establishment and maintenance of connection state information to the offload network adapter. As a result of this offloading of connection establishment and state information maintenance, the number of communications needed between the host system and the offload network adapter may be reduced. In addition, offloading of these functions to the offload network adapter permits bulk notification of established connections and state information to the host system rather than piecemeal notifications as is present in known computing systems.
