Abstract: Methods, apparatuses, and computer program products for sharing a transmission control protocol (TCP) port by a plurality of applications are provided. Embodiments include receiving, by a transmission controller from a client, a first TCP packet that includes an indication of a new TCP connection for a TCP port; determining, by the transmission controller, an origination of the first TCP packet; identifying, by the transmission controller, a TCP sequence number range associated with the determined origination; selecting, by the transmission controller, an initial sequence number (ISN) within the identified TCP sequence number range; and sending, by the transmission controller to the client, a second TCP packet that includes the selected ISN.

Abstract: 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.

Abstract: Provided are techniques related generally to computer communication and, more specifically, to techniques that provide legacy applications with access to a cluster infrastructure. A pseudo interface layer provides applications with internet protocol (IP) family sockets access to cluster awareness protocols in a manner that may be transparent to both the application and the cluster awareness layer of a kernel.

Abstract: In a computer system having memory, at least one processor and a physical input-output adapter, the at least one processor generates logical partitions, including local logical partitions and an input-output logical partition. The logical partitions have respective local virtual adapters. The input-output logical partition has a shared virtual adapter configured to communicate with the physical input-output adapter, such that a plurality of the local logical partitions share the physical input-output adapter via the shared virtual adapter. The at least one processor provides communication for ones of the local virtual adapters of the local logical partitions directly with the physical input-output adapter by a hypervisor.

Abstract: A method, system and computer program product is disclosed for providing thread specific protection levels in a multithreaded processing environment. The method comprises generating a group of threads in a process, one of the group of threads opening a thread entity, and that one of the group of threads specifying one or more levels of access to the thread entity for the other threads. In one embodiment, when a first of the threads attempts to perform a specified operation on the thread entity, the method of this invention determines whether that first thread is the one of the group of threads that opened the thread entity. When the first thread is not that one of the group of threads, the first thread is allowed to perform the specified operation if and only if that operation is permitted by the specified one or more levels of access.

Abstract: Provided is reporting session information for a session upstream from a server. A data processing system receives a session handshake from a first client for a session between the server and the first client. The system receives a session-descriptor for a session between a second client and the first client before handling a nested session. The system determines whether a user has made an upstream session request. The system obtains session data from an upstream data structure, responsive to a determination that the user has made an upstream session request. The system renders the session data based on the upstream session request.
