摘要： An approach is disclosed for implementing failover and resume when using ordered sequences in a multi-instance database environment. The approach commences by instantiating a first database instance initially to serve as an active instance, then instantiating a second database instance to serve as an instance of one or more passive instances. The active database establishes mastership over a sequence and then processes requests for the ‘next’ symbol by accessing a shared sequence cache only after accessing a first instance semaphore. The active instance and the passive instance perform a protocol such that upon passive database detection of a failure of the active database, one of the passive database instances takes over mastership of the sequence cache, and then proceeds to satisfy sequence value requests. The particular order is observed in spite of the failure.

摘要： Providing media on demand includes a trace-adaptive fragmentation scheme generating a plurality of segment fragmentation schemes for broadcasting data on a link across a network from a host to a set of clients. The set of data includes frames of information and can include media-on-demand, such as video-on-demand. The trace-adaptive fragmentation scheme considers a characteristic of the data in generating the plurality of segment fragmentation schemes. The trace-adaptive fragmentation scheme also selects one of the plurality of segment fragmentation schemes to use in broadcasting the data to the set of clients for each item of data included in the data. In selecting a segment fragmentation scheme for each item of data, the trace-adaptive fragmentation scheme attempts to reduce data loss in broadcasting the data to the set of clients and considers whether a segment fragmentation scheme reduces a gap between a peak aggregate rate of the data broadcast to the client and a minimal aggregate rate of the data broadcast to the client for simultaneously broadcast segments of data.

摘要： In accordance with a dynamic and recursive method, the number of required ADMs for a given set of light-paths in an OWDM ring network can be minimized. In one formulation of the minimum ADM problem, the method aims to create as many circular segments among the set of light-paths in the OWDM ring network as possible, and to form as few non-circular segments as possible from the remaining light-paths such that the number of shared ADMs can be maximized. In one example, the method of the invention operates in two phases: in the first phase, a dynamic and recursive searching for all the possible circular segments among the light-paths is employed, after which the concatenated circular segments are removed from further processing. Next, a reverse recursive searching among the remaining light-paths for concatenated non-circular segments with as many light-paths as possible is conducted.

摘要： A method and apparatus for broadcasting media objects for such bandwidth-intensive applications as Media on Demand (MoD) or Video on Demand (VoD) employ a novel StairCase Broadcast (SCB) scheme. A media server in accordance with one example of the invention includes a fragmenter that fragments media objects into multiple segments, with each segment provided to a corresponding streamer. Each streamer periodically and continuously streams data associated with its corresponding media segment on a connection between the server and a media client. A download controller in the media client selectively causes the proper streams to be received for downloading from the server in accordance with the fragmentation of the selected media object and the number of streams that the client can simultaneously receive for downloading. A selector is operable to cause data from each successive segment to be downloaded from the corresponding stream immediately regardless of the position in the period associated with the successive segment. By its design, the method and apparatus of the present invention allow for lossless broadcast of media contents with de-coupled per-media-object server and client bandwidth design considerations.

摘要： A method and apparatus are provided for determining the probability that one or more problems have occurred within a complex multi-host system. A probabilistic model representing the cause/effect relationships among potential system problems identifies the probability that a problem occurred in the system based at least on system measure states that are input into the probabilistic model. System measure states may be determined based on an aggregation of system measurement values taken periodically. Aggregating system measurement values may be performed over system measurement values that were taken during a recent time interval. A rolling count aggregation function may be used for this purpose. A rolling count function counts the number of system measurement values taken within the recent time interval that lie within a particular range of values. A system measure state may be determined based on whether the rolling count exceeds a threshold associated with the system measure.

摘要： A method and apparatus are provided for determining that problems have occurred within a complex multi-host system and for identifying for each problem, sequences of causes and effects called a fault cause path, starting with a root cause. A probabilistic model representing the cause/effect relationships among potential system problems identifies the probability that a problem occurred in the system. Such failure probabilities may be determined based on aggregating, over a recent time interval, probability of failure values determined by the probabilistic model. Each fault cause path may have an associated probability of accuracy value reflecting the expected accuracy of the fault cause path relative to other fault cause paths. When more than one fault cause path is identified, the number and order of the fault cause paths may be ranked and displayed based on their probability of accuracy value.

摘要： A method and apparatus are provided for performing cross-host root cause diagnosis within a complex multi-host environment. In a multi-host environment, sometimes system failures on one host may cause problems at another host within the same environment. A probabilistic model is used to represent failures that can occur within each host in the environment. The cause and effect relationships among these failures together with measurement values are used to generate a probability that each potential failure occurred in each host. When a problem is observed on one host without detecting a corresponding root cause within the same host, a cross-host failure diagnosis is performed. The probabilistic models for other hosts in the environment are used to determine the most likely cause of the failure.

摘要： A method and apparatus is provided for determining the most probable cause of a problem observed in a complex multi-host system. The approach relies on a probabilistic model to represent causes and effects in a complex computing system. However, complex systems include a multitude of independently operating components that can cause temporary anomalous states. To reduce the resources required to perform root cause analysis on each transient failure, as well as to raise the confidence in the most probable cause of a failure that is identified by the model, inputs to the probabilistic model are aggregated over a sliding window of values from the recent past.
