摘要： A method and apparatus for automatically generating a run-time instrumenter are disclosed. In accordance with the illustrative embodiment, an off-line analyzer first determines instrumentation locations for a program under test in accordance with a method called the Super Nested Block Method. After the instrumentation locations have been determined, source code for a run-time instrumenter is automatically generated based on the source code for the program under test and the instrumentation locations. The source code for the program under test and the run-time instrumenter are then compiled into executables, and a testing tool then executes the program under test and the run-time instrumenter in parallel.

摘要： A method for generating test cases for a program is disclosed. The method combines features of path-oriented and goal-oriented software testing. The illustrative embodiment constructs a control-flow graph with nodes that correspond to invocations of subroutines, and constructs control-flow graphs for the source code of such nodes as well. A metric that is based on the topology of the control-flow graph is evaluated recursively for nodes of the graph and for control-flow graphs that correspond to invoked subroutines. In the illustrative embodiment, the metric employed is the length of a shortest path from the starting node to a particular node. A node n with the highest metric value is then selected as a goal, and a path from the starting node to the ending node that passes through node n is generated via backtracking.

摘要： The present invention is directed to automatically analyzing software systems for identifying faults or bugs and/or detection of malicious code. In various embodiments, the present invention measures code coverage for high priority invocable program elements, uses a relaxed coverage estimation technique that, instead of guaranteeing which code units will be executed, guarantees that at least a certain number of code units will be executed, determines and solves constraints in code to identify infeasible paths containing one or more selected nodes, determines, for a composite data type, a range of values for each of at least two non-composite data fields, and/or translates, prior to code analysis complex code into simpler code having fewer operators.

摘要： Techniques for performing rapid fault detection and recovery in communication networks are disclosed. For example, in one aspect of the invention, a technique for detecting one or more conditions in a communication network comprises the following steps/operations. One or more keep-alive packets are transmitted from a source node in the communication network to a destination node in the communication network over two or more paths between the source node and the destination node, wherein the two or more paths are at least partially disjoint. Upon receipt of the one or more keep-alive packets at the destination node via the two or more paths, at least one quality measure is computed at the destination node for each of the two or more paths, the at least one quality measure being indicative of one or more conditions in the communication network. While not limited thereto, the invention is particularly well-suited to Internet Protocol (IP) telephony networks, particularly those that provide Voice over IP (VoIP) applications.

摘要： A method for determining the number and location of instrumentation probes to be inserted into a program is disclosed. The method advantageously inserts the minimum number of probes that are required to obtain execution coverage for every node in the program's control-flow graph. In addition, the method requires only type of node marking and one bit to store each probe, and does not require the assignment of weights to arcs or nodes of the control-flow graph. In the illustrative embodiment, the nodes of a control-flow graph are partitioned into non-empty sets, where each non-empty set corresponds to a super nested block of the program.

摘要： A mechanism for encoding and reporting instrumented data is disclosed that requires less storage space and incurs less processor overhead than other methods of the prior art. In accordance with the illustrative embodiment, a bit vector in shared memory corresponds to nodes of a program's control-flow graph that have been instrumented, and the contents of the vector indicate which of these nodes have executed; in addition, character strings in shared memory indicate what file, class, and method each node belongs to. A process that executes concurrently with those of the program under test transmits instrumented data from the shared memory to a database. The illustrative embodiment enables efficient, rapid reporting and storage of instrumented data, and is therefore especially well-suited for run-time analysis of real-time concurrent systems.

摘要： The present invention is a system and method for rapid network failure detection, identification and notification to internet users. It is particular applicable to VoIP applications where such real-time problem identification is particular valuable. It reduces failure detection time by coordinating the sending frequency of RTP and RTCP packets. These incoming packets are monitored and the failure to receive a predetermined number in a specified time window indicates that a network problem has occurred. This problem is then promptly communicated to users of the system.

摘要： A printer has a print engine with an ink supply chamber connected to the print engine. The supply chamber has an exit aperture to which a suction device is connected. A gas permeable film associated with the aperture separates the chamber from the suction device. The suction device may be a resilient spring member that occasionally is composed during winter carriage reciprocation to maintain suction, or may be a vacuum pump. A porous may support the film.
