摘要： A method of clustering communication nodes based on network attributes such as network delays and forwarding capacity; on communication interest attributes; and on application attributes such as quality of service preferences/constraints in providing communications between users and application servers. A multi-attribute communication feature vector is formed. That vector is comprised of network attributes, communication interests attributes, and quality of service requirements and is used to form efficient group communication mechanisms for distributed collaborative applications. Then the multi-attribute communication feature vectors are clustered. The clustering methods for multi-type attribute feature vectors are: iterative clustering using a generalized distance space with normalized attribute subspace metrics; fusion clustering, and nested clustering.

摘要： A method and apparatus for managing communications for collaborative applications. Middleware uses, network, application, and middleware resource information together with user information to facilitate communications between the application resources and the users via a hierarchical control structure that implements a communication overlay tree. That overlay tree is implemented in view of network constraints, and on the users and on their communication constraints. The middleware provides user index identifiers that inform the application that specific users have communication interests in specific parts of the application space. To send data to users that are interested in a specific part of the application space the application sends that data with a list of user index identifiers. The middleware then associates the user index identifiers with individual users and routes sent data to the individual users along the overlay tree.

摘要： A method, computer readable media, and apparatus of hierarchical-based communication session and data distribution management that indexes client's communication preferences and network attribute information. Indexing is used to generate dynamic group membership lists that map into communication groups. Indexing is replicated at control nodes in the network overlay to allow distributed management of group membership. Send/receive operations are decoupled through data distribution and the indexing structure. Senders and receivers register their group communication interests to a parent node in the hierarchy. The session control structure aggregates client interest and dynamically updates replicas at control nodes which are selected according to the changes in registered client interest. The indexing structure has self-managing properties for automatic clustering based on client session and data interests, and dynamic partitioning of the session/data interest attribute space. Group membership is managed by querying the indexed session/data distribution management structure and mapping output to communication groups.

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 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.

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. 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 the hard state of the protocol. A preferred embodiment of the present invention performs a failover of a network offload engine by temporarily blocking the reception of network packets, recovering hard state from host information, resuming network operation using a substitute network offload engine, and recovering soft state from the subsequent network activity.
摘要翻译：本发明提供了一种用于有效地恢复网络卸载引擎的状态和执行故障切换的方法，计算机程序产品和数据处理系统。本发明区分协议的硬状态和软状态。硬态是状态信息，当丢失时会导致不正确的协议行为。软状态是可能丢失或变得不一致而不失去正确性的状态信息。本发明通过总是能够恢复协议的硬状态来确保正确性。本发明的优选实施例通过暂时阻止网络分组的接收，从主机信息恢复硬状态，使用替代网络卸载引擎恢复网络操作，以及从后续网络活动中恢复软状态来执行网络卸载引擎的故障转移。

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. 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.
