    Abstract: A method for profiling performance of a system includes steps of: monitoring execution of the system at multiple points during the system's operation; analyzing results derived from the monitoring in order to provide analyzed results; reconfiguring the monitoring non-uniformly according to the analyzed results; and repeatedly performing iterations of the above steps until a particular event occurs. The iterations may be terminated upon: reaching a specified level of analysis precision, determining a source of one or more performance bottlenecks, determining a source of unexpectedly high output or low completion time, completing a predefined number of iterations, reaching an endpoint of an application, or having performed iterations for a specified period of time.

    Abstract: A system and method for processing a request by a first control service using a first control specification language, and a second control service using a second control specification language includes steps of: receiving the request from a requestor; providing the request to the first and second control services; receiving a decision on the request from each of the first and second control services; and comparing the decisions. The first control specification language is an access control policy.

    Abstract: A method to create an instance of a defect-based production and testing process analysis machine (DPTPAM) provides continual process improvement based on foundational questions and classified defect data. The method includes the following steps: obtaining domain specific questions; developing a domain specific classification scheme that supports the answering of the foundational and domain specific questions; determining a method of using the domain specific classification scheme to answer both the foundational and domain specific questions; and creating a domain specific DPTPAM instance embodying the domain specific classification scheme and the method of answering the foundational and domain specific questions. The method can be implemented with a machine and a computer readable medium comprising logic for performing the method.

    Abstract: A multimedia stream is multicasted. A request to perform the multicast is received. A plurality of distribution nodes are assigned to provide the multicast to a plurality of receivers. The assignment of a node is based on the transformation capabilities of that node. The multicast is then performed and the assigned node performs its transformation. The transformed multicast is distributed to a receiver which is suitable for receiving the transformed multicast.

    Abstract: A method and system of collaboratively caching information to allow improved caching decisions by a lower level or sibling node. In a caching hierarchy, the client and/or servers may factor in the caching status at the higher level in deciding whether to cache an object and which objects are to be replaced. The PICS protocol may be used to pass the caching information of some or all the upper hierarchy down the hierarchy. Furthermore, the caching status information can also be used to direct the object request to the closest higher level proxy which has potentially cached the object, instead of blindly requesting it from the next immediate higher level proxy. A selection policy used to select objects for replacement in the cache may be prioritized not only on the size and the frequency of access of the object, but also on the access time required to get the object if it is not cached. The selection policy may also include a selection weight factor wherein each object is assigned a selection weight based on its replacement cost, the object size and how frequently it is modified. Non-uniform size objects may be classified in ranges of selection weights having geometrically increasing intervals. Multiple LRU stacks may be independently maintained wherein each stack contains objects in a certain range of selection weights. In order to choose candidates for replacement, only the least recently used objects in each group need be considered.
