    摘要： A topology propagation facility is provided for maintaining a common network topology database at different nodes in a distributed computing environment. The facility generates no message traffic when the distributed computing environment is in steady state. This is accomplished by discontinuing sending of group connectivity messages during a time period of no topology change within the distributed environment. Sending of group connectivity messages is reinitiated from at least one group leader upon identification by the group leader of at least one topology change within the distributed computing environment. Group connectivity messages are forwarded from one group of nodes on a first network to another group of nodes on a second network using a node common to both groups of nodes. The networks of the distributed computing environment can comprise heterogenous networks such that the topology propagation facility presented facilitates interoperability of the networks.

    摘要： A functional testing technique is provided employing an abstraction matrix that describes a complex software component to be tested. The abstraction matrix includes state and event information. The technique is an automated process which parses the abstraction matrix to generate test cases and mapped expected results therefore. The test cases are separated based on layers of the software component and data structures are associated with the separated test cases of the layers. The data structures allow the test cases of the various layers to be uncorrelated. The software component executable is employed to generate test case execution threads from the test cases and mapped expected results for a particular layer. These execution threads can then be executed in parallel, thereby testing the software component.
