Abstract: PROBLEM TO BE SOLVED: To provide an application independent in-kernel cache.
SOLUTION: A cache object being a method and tool for storing contents is given by utilizing a mechanism supplied by an operating system. A system that acquires storage for the cache object is implemented. Techniques for allowing multiple varying sources of data are defined. Multiple data sources may provide application specific/or application independent data using various protocols. The cache object storage mechanisms are independent of the data sources and vise versa. Techniques for high-speed lookup and management of the cache objects are defined. Mechanisms for moving the data from the data source into the cache object storage mechanism are implemented.

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 (730) is provided. The connection establishment mechanism provides the ability to offload connection establishment (1030) and maintenance of connection state information to the offload network adapter (730). As a result of this offloading of connection establishment (1030) and state information maintenance, the number of communications needed between the host system (710) and the offload network adapter (730) may be reduced. In addition, offloading of these functions to the offload network adapter (730) permits bulk notification of established connections and state information to the host system (710) rather than piecemeal notifications as is present in known computing systems.
Abstract translation: 提供了从主机处理器卸载协议处理的网络适配器的许多改进。 具体地，提供了一种用于改善利用卸载网络适配器（730）的系统中的连接建立的机制。 连接建立机制提供将连接建立（1030）卸载并将连接状态信息维护到卸载网络适配器（730）的能力。 作为连接建立（1030）的卸载和状态信息维护的结果，可以减少主机系统（710）和卸载网络适配器（730）之间所需的通信次数。 此外，将这些功能卸载到卸载网络适配器（730）允许向主机系统（710）批量通知所建立的连接和状态信息，而不是如已知的计算系统中存在的分段通知。

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