摘要： A method, computer program product and system for processing TCP/IP packets. A TCP protocol stack may store a payload of a received TCP/IP packet in a data fragment list. The TCP protocol stack may further read the header of the received packet to extract a value used to index into a table storing a list of transport control blocks (TCBs). The TCP protocol stack may further perform a lock and a read operation on the TCB indexed in the table. The TCP protocol stack may further transmit the payload to the TCP application without requiring the application to perform a lock, read, write or unlock operation on the indexed TCB since the TCP protocol stack and the TCP application are operating on the same thread. By the TCP application foregoing the lock, read, write and unlock operations on the TCB, there is a reduction in the number of memory accesses.

摘要： System and method for maintenance and examination of timers for a computer system having connections in a networking system. Timer values in a connection table each indicate a timeout for a timer for a connection, where each connection has multiple timers, and one of the timer values is written to a global timer array for each connection such that the global timer array can be scanned to determine when timeouts occur for active connections. Sparse restart of a timer includes restarting the timer if data is communicated with a connected computer before the timeout occurs and after a predetermined time interval after timer start, and not restarting the timer if data is communicated before the timeout occurs and within the predetermined interval after timer start.

摘要： A computer-implemented method, system, and article of manufacture for data communication between a requester and a responder in a remote direct memory access (RDMA) network, where each of the requester and the responder is an RDMA-enabled host of the network. The method includes: sending a request for the responder to provide data, where the request includes a mapped steering tag that is obtained by mapping a set of memory buffers of the requester onto a single representation that allows for identifying each of the memory buffers of the set; and receiving the requested data together with the mapped steering tag and assigning the data being received to the memory buffers of the set consistently with the mapping.

摘要： Exemplary embodiments include RDMA methods and systems for sending application data to a computer memory destination in a direct but non-blocking fashion. The method can include posting a new work request for an RDMA connection or association, determining if there is a prior work request for the same connection or association enqueued for processing, in response to a determination that no prior work request is enqueued for processing, processing the new work request directly by sending RDMA frames containing application data referred to by the work request to the computer memory destination, performing direct sending while there is sufficient send space to process the new work request, and delegating the new work request to asynchronous transmission if a prior work request is already enqueued for processing or lack of send space would block a subsequent transmission operation.
摘要翻译：示例性实施例包括用于以直接但非阻塞方式将应用数据发送到计算机存储器目的地的RDMA方法和系统。该方法可以包括对RDMA连接或关联发布新的工作请求，确定是否存在用于处理的相同连接或关联的先前工作请求，以响应于确定没有先前的工作请求被入队用于处理，处理通过将包含由工作请求引用的应用数据的RDMA帧发送到计算机存储器目的地直接发送新的工作请求，在存在足够的发送空间来处理新的工作请求的同时执行直接发送，并且将新的工作请求委托给异步传输，如果先前工作请求已经入队处理或缺少发送空间将阻止后续的传输操作。
