摘要： Disclosed is a technique for data network congestion diagnosis using remote estimation of round-trip delays. A monitoring node transmits test messages between network nodes and measures the transit times between when the test messages are transmitted from, and when they return to, the monitoring node. A path delay between network nodes is determined based on the measured time delays. The techniques for determining network path delay are also utilized in conjunction with a three phase test procedure for diagnosing network congestion problems. Due to various network topologies and routing tables, certain confirmatory checks may be required to determine whether the procedures of the first or second phase test procedures are appropriate for particular path segments. Further, queuing delays may be determined by subtracting traffic independent delays from the measured transit times of the test messages, and such queuing delays may be used to determine the path delays. Such traffic independent delays may be determined during periods of low network traffic.
摘要翻译：公开了一种使用远程估计往返延迟的数据网络拥塞诊断技术。监控节点在网络节点之间传输测试消息，并测量从测试消息发送到何时以及返回到监视节点之间的传输时间。基于测量的时间延迟来确定网络节点之间的路径延迟。用于确定网络路径延迟的技术还结合用于诊断网络拥塞问题的三相测试程序来使用。由于各种网络拓扑和路由表，可能需要进行某些确认性检查，以确定第一阶段或第二阶段测试过程的过程是否适合于特定的路径段。此外，可以通过从所测量的测试消息的测量的传播时间中减去业务独立的延迟来确定排队延迟，并且可以使用这种排队延迟来确定路径延迟。这样的流量独立延迟可以在低网络流量的时段期间确定。

摘要： A method for distributed computations for fault-diagnosis in a system whose fault propagation model has deterministic couplings between faults and symptoms includes creating a 'relation graph' in which the nodes correspond to the potential faults, with two nodes connected by a 'relational link' if their corresponding faults have an observed symptom in common. The relation graph is then partitioned into several domains, while minimizing the number of cross-domain relational links, which correspond to cross- domain symptoms. In each domain, all the optimal local solutions to the domain's sub- problem are first determined, and then a combination is selected of the local solutions, one from each domain, that explains the maximum number of cross-domain symptoms, where the optimal solution is supplemented, if necessary, with additional faults to explain any remaining unexplained cross-domain symptoms, determining also a bound on the deviation from optimality of the global solution.

摘要： Disclosed is a technique for data network congestion diagnosis using remote estimation of round-trip delays. A monitoring node (110) transmits test messages between network nodes and measures the transit times between when the test messages are transmitted from, and when they return to, the monitoring node. A path delay between network nodes is determined based on the measured time delays. The techniques for determining network path delay are also utilized in conjunction with a three phase test procedure for diagnosing network congestion problems. Due to various network topologies and routing tables, certain confirmatory checks may be required to determine whether the procedures of the first or second phase test procedures are appropriate for particular path segments. Further, queuing delays may be determined by subtracting traffic independent delays from the measured transit times of the test messages, and such queuing delays may be used to determine the path delays. Such traffic independent delays may be determined during periods of low network traffic.

摘要： This invention provides an automated adaptive method for identity verification of' claimants that attempt to get access into a resource by responding to a sequence of identifiers. The sequence has a specified maximal length and the identifiers are partitioned into multiple groups where identifiers in the same group are correlated and identifiers in different groups are not correlated. The method guarantees that an impostor will be accepted with a probability that does not exceed a specified parameter and that a legitimate claimant will be rejected with a probability that does not exceed a different specified parameter. The method also computes the probabilities that a legitimate claimant, or an impostor, will terminate an interrogation session with an inconclusive result, which would necessitate further manual interrogation. The method is adaptive as the conditional probabilities of an impostor's responses change throughout a session of interrogation.
