摘要： A computer implemented method, apparatus, and computer usable program code to determine whether an acknowledgment packet from an end point acknowledges receipt of unsent data in response to receiving the acknowledgement packet over a connection with the end point. A determination is made as to whether acknowledgement packets for unsent data have been received sequentially a selected number of times over the connection in response to the acknowledgement packet being for unsent data. The acknowledgment packet is dropped if acknowledgement packets have been received sequentially the selected number of times over the connection.

摘要： A host enables any adapter of multiple adapters of the host to concurrently support any VIPA of the multiple VIPAs assigned to the host. Responsive to a failure of at least one particular adapter from among the multiple adapters, the host triggers the remaining, functioning adapters to broadcast a separate hardware address update for each VIPA over the network, such that for a failover in the host supporting the multiple VIPAs the host directs at least one other host accessible via the network to address any new packets for the multiple VIPAs to one of the separate hardware addresses of one of the remaining adapters.
摘要翻译：主机允许主机的多个适配器的任何适配器同时支持分配给主机的多个VIPA的任何VIPA。响应于多个适配器中的至少一个特定适配器的故障，主机触发剩余的功能适配器以通过网络为每个VIPA广播单独的硬件地址更新，使得对于支持多个VIPA的主机中的故障转移主机引导至少一个可通过网络访问的其他主机，将多个VIPA的任何新数据包解析为其余一个适配器之一的单独硬件地址之一。

摘要： Methods, systems, and media to reduce delays associated with port assignments are disclosed. More specifically, embodiments include hardware and/or software to delay binding of selected port numbers to instances of applications. Some embodiments identify port numbers for which applications generate multiple bind calls that may connect with unique remote ports. The port numbers are stored in a port list that is accessible to the protocol stack and memory is allocated for storing flags and additional port configuration data. When a bind call is associated with a port number bound to another application instance and the port number is included in the port list, the bind call may then be delayed until a connect is received from the corresponding application instance. When the resulting four tuple is unique for the computer system, the corresponding application instance is bound to the port number and connected with the remote port.

摘要： Methods, systems, and products for migrating logical partitions. The method may include dynamically discovering a destination system for migration; remotely creating an environment on the destination system for accepting, the runtime migration; and migrating a running logical partition from a source system to the destination system. The source system may be managed by a source management system and the destination system may be managed by a destination management system. Dynamically discovering the destination system for migration may comprise establishing a communications channel between the source management system and the destination management system; obtaining a list of candidate systems from the destination management system; and validating resources of at least one candidate system.

摘要： A method, system and computer program product for transferring data between two applications over a local network connection. The invention establishes a socket connection between the applications and transfers data through the socket connection using a pseudo socket layer interface when the two endpoints of the socket connection are on the same host. Socket application program interface comprises socket buffers for sending and receiving data. A connecting application identifies and establishes a connection with a listening socket, and places data directly in the socket receive buffer of the receiving socket. If the other end of the socket connection is on a remote host, then data is transferred using underlying network facilities.
