Abstract: A client/server network enables access to non-HTML objects from a web browser. The system includes a database for storing non-HTML files. A system user requests a non-HTML file from a database using a web browser. The web browser transmits the requests to a server via a HTTP server and module. The server locates and retrieves the object requested. The module translates the object to a format supported by the web browser. The HTTP server communicates the translated file to the web browser over a network. The web browser then presents the translated file to the system user.

Abstract: In a mainframe class data processing system having multiple logical partitions and a port to a network, a host-network interface is established for reducing network overhead at the multiple partitions. The host-network interface includes, for example, a host channel connection coupling the multiple partitions of the host system to a communications adapter having a network device driver for each network coupled to the adapter. The adapter also includes an address resolution protocol (ARP) cache designed to hold predetermined media headers for the clients coupled to the network(s) for use in forwarding an internet protocol (IP) datagram across the network to one of the clients from a partition of the host system. Provision is also made for partition-to-partition communication of IP datagrams by storing IP addresses of the logical partitions as HOME addresses in the ARP cache of the adapter.

Abstract: A method for producing and verifying the integrity and authenticity of a digital container. The digital container includes digital information in the form of data files or other digital containers along with security attributes associated with the digital information. In one embodiment, the production of the digital container comprises (i) producing a container archive by compressing a combined result of digital information and a signed archive manifest associated with the digital information and (ii) compressing a combined result of container archive and a signed container manifest associated with the container archive. This produces the digital container for use in preventing unauthorized observation or manipulation of the contents of the data files for example.
Abstract: A technique is provided for resynchronizing message traffic in a communication network following network component failure. A failing component, upon restart, retrieves stored control information including a SYNC number and byte sequence number (BSN) from external memory. The SYNC number is then incremented by a predetermined amount to obtain a new SYNC number, with the predetermined amount being sufficient to ensure that the new SYNC number comprises a current SYNC number. Assuming that the failure occurs at a first data processing system in the network, a status request message is sent from the first data processing system to a second data processing system across the logical connection. The status request includes the new SYNC number, and the BSN read from the external memory. The first data processing system waits for a response message to its status request message. The response message contains a BSN of a next piece of data that the second data processing system is expecting.

Abstract: A server computer 11 in a data transmission system receives data processing demand packets sent in from any of a plurality of terminal computers on the network via a specific terminal port on the switching hub, and a group of sending data packets is formed against the data processing demand packets and at the same time this sending data packet group is sent, via the specific terminal port, to the terminal computer 12 that sent out the data processing demand packet.
