Abstract: A multiprotocol transport network (MPTN) gateway provides transparent interconnection of two or more SPTNs (12, 14, 16, 18) running different transport layer protocols to form an integrated heterogeneous MPTN. The MPTN gateway of the present invention has no dependencies on the particular transport protocols running on the SPTNs being interconnected as it utilizes a common transport provider (a Gateway Services Protocol Boundary (GSPB)) (38) between the SPTN transport protocols and the gateway components. The MPTN gateway supports connections between end systems across multiple intermediate networks. The MPTN gateway provides automatic routing based on dynamic participation in the routing protocols of the interconnected SPTNs so that any number of gateways may be interconnected and in any topology desired. As the MPTN gateway has a general architecture and acquires routing information automatically, it supports not only other MPTN nodes and gateways but also non-MPTN nodes and gateways.

Abstract: A method, system, and article are provided to enable a Hyperswap operation in a clustered computer system. Each node in the system is configured with flash memory, with a hierarchical list of boot volumes therein. Following a Hyperswap operation, the current boot volume is communicated to each node in the cluster and each node joining the cluster. All previously inactive nodes that were booted from the improper boot volume are re-booted from the correct and the flash memory is amended to reflect the correct boot volume.

Abstract: Ein Verfahren, ein System und ein Artikel werden bereitgestellt, um einen dynamischen Austausch von Replikat-Datenträgern in einem Verbundcomputersystem bereitzustellen. Jeder Knoten in dem System ist mit einem Flash-Speicher eingerichtet, der eine hierarchische Liste von Start-Datenträgern beinhaltet. Im Anschluss an einen dynamischen Austausch von Replikat-Datenträgern wird der aktuelle Start-Datenträger an jeden Knoten in dem Verbund und an jeden Knoten, der in den Verbund eintritt, übermittelt. Alle zuvor inaktiven Knoten, die von dem inkorrekten Start-Datenträger gestartet wurden, werden von dem korrekten neu gestartet, und der Flash-Speicher wird so geändert, dass er den korrekten Start-Datenträger wiedergibt.

Abstract: A Transport Layer Protocol Boundary (TLPB) architecture is described which will permit an application program to run over a non-native transport protocol without first generating a protocol compensation package tailored to the transport protocols assumed by the program's application programming interface and by the available transport provider. All transport functions required by the program are converted to standardized or TLPB representations. When a connection between the first application program and a second remote application is requested, the individual required TLPB transport functions are compared to corresponding functions supported by the transport provider. Compensations are invoked only where there is a mismatch. The node on which the remote application program runs is informed of the compensations so that necessary decompensation operations can be performed before the data is delivered to the remote application program.

Abstract: Disclosed are a method and a system for transmitting a message or data packet from a single sender to a plurality, i.e. a group of receivers, usually called multicasting, within a conventional unicast transmission network, i.e. a network basically not equipped to handle such multicast transmissions, consisting of a plurality of subnetworks. The nodes or gateways connecting the subnetworks maintain tables of multicast receiving stations (or groups of such) and the header of each message includes information defining the groups of the addressed multicast receiving stations.
