摘要： A lightweight probabilistic mechanism used to estimate the number of active flows, which estimate is used to determine the probability of admitting a new flow into the network. In one embodiment, a method for controlling admission of new flows at a node in a network of nodes interconnected by links includes: (a) for each of a plurality of incoming packets arriving at the node, each incoming packet corresponding to an active flow traversing the node: (al) randomly selecting a packet from an output buffer of the node; (a2) determining whether the incoming packet is from the same active flow as the randomly-selected packet; and (a3) updating an estimate of the number of active flows traversing the node based on the determination of step (a2); and (b) determining whether to admit or drop part or all of a new flow at the node based on the estimated number of active flows traversing the node.

摘要： A network configuration that supports latency-equalization (LEQ) routing by effectively "storing" packets on communication links, rather than at end points. A suitable network configuration is found by (i) identifying a candidate pool of routers through which the participating client terminals and application servers can exchange packets intended for LEQ routing and (ii) analyzing the delay inventory corresponding to the network paths connecting the client terminals and application servers, through those routers. Based on the analysis, M routers from the candidate pool are selected to serve as hub nodes. Each participating client terminal is assigned m of these M hub nodes and, thereafter, directs and receives its packets intended for LEQ routing through one of these m hub nodes.

摘要： The need to monitor real time network services has prompted service providers to use new measurement technologies,. such as service-specific probes. A service-specific probe is an active probe that closely mimics the service traffic so that it receives the same treatment from the network as the actual service traffic. Service-specific probes are end-to-end and their deployment depends on solutions that address questions such as minimizing probe traffic, while still obtaining maximum coverage of all the links in the network. A polynomial-time probe-path computation algorithm is provided as well as a 2-approximate solution for merging probe paths when the number of probes exceeds a required bound k. The algorithms are evaluated using ISP topologies generated via Rocketfuel. For most topologies, it is possible to cover more than about 98% of the edges using just about 5% of the nodes as terminals.

摘要： An improved system and method for network fault and anomaly detection is provided based on the statistical behavior of the management information base (MIB) variables. The statistical and temporal information at the variable level is obtained from the sensors associated with the MIB variables. Each sensor performs sequential hypothesis testing based on the Generalized Likelihood Ratio (GLR) test. The ouputs of the individual sensors are combined using a fusion center, which incorporates the interdependencies of the MIB variables. The fusion center provides temporally correlated alarms that are indicative of network problems. The detection scheme relies on traffic measurement and is independent of specific fault descriptions.
