Techniques are provided for testing new software slated to be deployed on a target machine population with a number of target machines having a number of existing software programs. Method steps can include obtaining a list of depending software programs on selected ones of the target machines. The list can include those of the existing software programs which depend on the new software and/or those of the existing software programs on which the new software depends. The steps can further include identifying relevant test cases based on the list of depending software programs, instantiating a plurality of test client platforms characteristic of the target machine population, and testing the relevant test cases on the plurality of test client platforms to identify failures.

Method and apparatus for testing software

A method and system for combining the bandwidth available to a user communications device from multiple access points by switching output requests and corresponding replies to such requests among a plurality of such access points. In the simplest implementation the switching can be on a round-robin basis, but the switching can be enhanced to prioritize and use quality of service requirements associated with each output request, and also to measure congestion at each access point and base switching upon the congestion level. The invention operates by generating subset ISO communication stacks for each available access point, preferably the subset from the IP layer to the data control link, and switching between these stacks.

Increasing link capacity via traffic distribution over multiple Wi-Fi access points

Techniques for replicating data in a system having a data tier with a plurality of data sources and an application tier with a plurality of applications are provided. Such techniques can include creating an instance of an information model of the data that is specified by a schema. The model can be created in a form that is suitable for manipulation by at least one of the applications and that forms at least a portion of a model tier that is intermediate the data tier and the application tier. A replica of an instance of the information model can be created in a form suitable for remote transmission, and a consistency policy can be obtained that specifies a level of consistency required between the instance of the information model and the replica.

Method and system for model-based replication of data

A method, system, and computer program product are provided for managing data in a browser-based application. The application is opened in the browser, and a subset of the application is arbitrarily specified as data. Different versions of the subset of the application specified as data are caused to persist so that they may be recovered later. Persistence and recovery of the subset of the application specified as data are performed in a manner transparent to the application.
