Patent number: 7290028Abstract: Methods, systems and computer program products are provided for providing transactional quality of service providing transaction service level information from an application requesting a data transmission transaction to a communication process executing on a data processing system. The transaction service level information is provided separate from the data for the data transmission transaction. A quality of service level associated with the data transmission transaction is determined based on the transaction service level information received from the application. Other embodiments also provide for establishing a quality of service level without reference to transaction data content while further embodiments provide for establishing a quality of service level for responses.Type: GrantFiled: January 16, 2001Date of Patent: October 30, 2007Assignee: International Business Machines CorporationInventors: Roy Frank Brabson, John L.

Patent number: 6976083Abstract: An apparatus for providing direct data processing access in a network computing system environment. The system environment has a main storage which can be connected to one or more application servers and is in processing communication with an interface element. The interface element has at least one adapter and can be connected to one or more application user(s). One or more queues are established in the main storage that can handle data without causing interrupts in the running programs. Incoming data is received using the adapter and as data is received or modified, the status of the network computing system will be updated to reflect the new data or change. Data is then processed in the main storage after interrogating the multiple existing queues in the main storage simultaneously and forwarding them in turn to their appropriate destination or application server after a determination has been made by interrogating these queues.Type: GrantFiled: February 19, 1999Date of Patent: December 13, 2005Assignee: International Business Machines CorporationInventors: Michael E. Baskey, Steven G. Glassen, Eugene P. Hefferon, Bruce H. Ratcliff, Arthur J. Stagg, Stephen R. Valley

Patent number: 6778540Abstract: A facility is provided to allow for dynamic configuration of data routing between TCP/IP stacks of multiple partitions of a multi-partition processing system and a network adapter such as a local area network (LAN) gateway for the multi-partition processing system. The facility includes a command for automatically providing the network adapter with information that a particular partition of the processing system is to function as a router; and using the information at the network adapter to forward data received across the network to the partition when the data is to an unregistered HOME internet protocol (IP) address. The forwarding of data to the router partition occurs without any conventional IP processing.Type: GrantFiled: May 31, 2000Date of Patent: August 17, 2004Assignee: International Business Machines CorporationInventors: Bruce H. Ratcliff, Arthur J. Stagg, Stephen R. Valley

Patent number: 6681258Abstract: A facility is provided to allow retrieval of specific parameters by a communications stack (e.g., TCP/IP) of a multi-partitioned processing system from a shared network adapter coupling the processing system to a network. The processing system includes multiple communications stacks, each of which registers internet protocol (IP) addresses with the network adapter in an address resolution table shared by the multiple communications stacks. The facility includes query request and reply commands for selectively retrieving specific data from the shared address resolution table, wherein the specific data can include: local registered IP addresses for a communications stack issuing a query request, network address resolution entries associated with a particular HOME IP address, HOME IP addresses of one or more other communications stacks sharing the network adapter, IP addresses owned by other entities on the network, IP addresses which are in the address cache, as well as other types of data.Type: GrantFiled: May 31, 2000Date of Patent: January 20, 2004Assignee: International Business Machines CorporationInventors: Bruce H.

Patent number: 6401145Abstract: A method of transferring data in a network computing environment having a controlling program and a main storage in processing communication with an interface element including one or more adapters. A queuing mechanism is first established in the main storage for asynchronous transmittal of data between the program and said interface element. At least one queue-set is dedicated to input data and another queue-set to output data in the queuing mechanism. Queuing priorities both for said input and output queue-sets are then determined according to importance of data to be processed or transferred or other internal dependencies and a queue-description record is established by passing a QDIO queue command. From this the priority and number of the output queue are provided by order in which the order specified in the queue descriptor record relative to any other output queues described in that record.Type: GrantFiled: February 19, 1999Date of Patent: June 4, 2002Assignee: International Business Machines CorporationInventors: Michael E.

Patent number: 6345329Abstract: A method and apparatus for exchanging data in a network computing system having a main storage capable of connecting to at least one application server and an interface element with at least one adapter capable of establishing processing communication with at least one application user(s). A state change signalling protocol is used for transfer of data between the main storage and said adapter. In addition a queuing mechanism is established in the main storage having a plurality of queues each with a plurality of buffers. Some of these queues are dedicated to be input and others as output queues. By applying the protocol each input and output data buffer is associated with each of the active input and output queues. In this manner the input and output buffers are managed by placing the buffers into various states which are maintained in a special location that is set aside and is associated with each buffer.Type: GrantFiled: February 19, 1999Date of Patent: February 5, 2002Assignee: International Business Machines CorporationInventors: Michael E.

Patent number: 6345325Abstract: A method and an apparatus for timely and accurate processing of data in a network computing environment controlled by a running program and having a queuing mechanism established in a main storage. The main storage is in processing communication with an interface element having one or more adapters. At least one set of queues in the queuing mechanism is designated for input and another set for output. A signal adapter instruction can be issued to provide initiative to check content of any or all queues in the mechanism. With the help of the signal adapter an initiate-output can be specified when appropriate and the associated adapter can then asynchronously process the input or the output queues. A synchronize option is also available to signal the associated data queues to update all entries in order to render them current as observed by both the adapter and the controlling running program.Type: GrantFiled: February 19, 1999Date of Patent: February 5, 2002Assignee: International Business Machines CorporationInventors: Michael E.
