摘要： 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.
摘要翻译：提供了从主机处理器卸载协议处理的网络适配器方面的许多改进。具体来说，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。连接建立机制提供卸载连接建立（1030）和将连接状态信息维持到卸载网络适配器（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）之间所需的通信数量。另外，将这些功能卸载到卸载网络适配器（730）允许向主机系统（710）批量通知已建立的连接和状态信息，而不是如已知计算系统中存在的零散通知。

摘要： 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 (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).

摘要： The present invention provides a method, computer program product, and data processing system for efficiently recovering state and performing failover of a network offload engine (904). The present invention distinguishes between the hard state and the soft state of a protocol. Hard state is state information that, when lost, leads to incorrect protocol behavior. Soft state is state information that may be lost or become inconsistent without loss of correctness. The present invention ensures correctness by always being able to recover (1002) the hard state of the protocol. A preferred embodiment of the present invention performs a failover of a network offload engine (904) by temporarily blocking (908) the reception of network packets, recovering (1002) hard state from host information, resuming network operation using a substitute network offload engine (906), and recovering (1008) soft state from the subsequent network activity.
