Abstract: In general, methods and apparatus for implementing a Quality of Service (QoS) model are disclosed. A Quality of Service (QoS) contract with an initiating network device may be satisfied. A request may be received from the initiating network device in a first time less than or equal to an ordinal number times an arrival interval. The ordinal number signifies a position of the request among a group of requests. The request that has been serviced may be returned to the initiator in a second time less than or equal to a constant term plus the ordinal number times a service interval.

Abstract: It is one object of the present invention to provide a program execution method for performing greater optimization. A program execution apparatus according to the present invention performs a transfer from an interpreter process to a compiled code process in the course of the execution of a method. At this time, if no problem occurs when a transfer point is moved to the top of a loop, the transfer point for code is so moved. And when a transfer point is located inside a loop, a point that post-dominates the top of the loop and the transfer point is copied to a position immediately preceding the loop. Then, information for generating recalculation code is provided for the transfer point, and a recalculation is performed.

Abstract: A system for creating and viewing simulation models that are used for managing requirements and design specifications for complex systems. Users simultaneously collaborate on the description of a complex system such as an enterprise software project throughout its life cycle. User interfaces, designed to assist in the visualization of a particular form of knowledge, allow users to describe the complex system with simple interactive elements. Information in all perspectives is presented so that it is legible and discernable to a non-technical audience. Multi-dimensional data structures record all the resulting information, creating a simulation model of the complex system, and the tasks required for construction and maintenance. Tasks are driven from the specifications not as a separate activity, but as part of the same activity to facilitate project management by allowing decisions to be tracked virtually throughout the simulation model.

In one of the first and second USB devices that is operating as a peripheral device, the device driver control circuit receives information on the device driver of the other USB device, operating as a host device, when the first and second USB devices are firstly connected to each other; and updates the first memory region in accordance with the received information.

Abstract: A cyclic graph may be partitioned. The partitions of the cyclic graph may include an acyclic component of the cyclic graph and a set of partitioned links. The partitions of the cyclic graph may have a particular order. The elements of the cyclic graph may be serialized with a particular serialization order. The serialization order of the elements of the cyclic graph may correspond to the order of the partitions of the cyclic graph. The elements of the acyclic component of the cyclic graph may be serialized before the elements of the set of partitioned links. A computer system may include a graph synchronization component configured to partition the cyclic graph and determine the serialization order of the elements of the cyclic graph. A serialization of the cyclic graph does serialize the elements of the cyclic graph in the determined serialization order.

Abstract: The invention provides an improved method for detecting concurrent bugs in multi-threaded software having at least one command to access a non-atomic variable. The non-atomic variable may have a plurality of memory words. In one approach, the method generally involves storing the memory words as atomic variables and replacing the at least one command to access the non-atomic variable with separate instructions to access each of the atomic variables. A thread-switch command is inserted between the atomic variable access commands to increase the likelihood of exposing and detecting synchronization problems.

Abstract: An automated system performs multiple tests for identifying an operating system executed by a network node. A combination of multiple tests may be calibrated to generate an acceptably accurate operating system identification. An identification module makes an overall identification based on identifications of the tests. A plurality of identification rules may determine which of the individual tests is likely to be most accurate. The system also may include a conflict resolution module that resolves conflicts among the multiple tests. The conflict resolution module may employ a plurality of conflict resolution definitions that define special cases in which the general identification rules may be overridden to make an identification without regard to the general identification rules. Alternatively, the conflict resolution module may be configured to work in combination with the general identification rules to make an operating system identification.

Abstract: Constraints are defined in view of a program implementation. Constraints check program state or variables to maintain data consistency. A constraint component determines a constraint's scope and variables upon which a constraint depends. Program flow is altered so constraints are checked whenever a variable upon which a constraint depends is updated. Optionally, program flow is altered dynamically to re-establish constraints whenever a variable upon which a constraint depends is updated. Re-establishing constraints provides efficiency, since a program flow is altered for a minimum cost based on a present evolving minimum set of active constraint-variable relationships.
