Opportunistic Flow-level Latency Estimation using NetFlow

Opportunistic Flow-level Latency Estimation using NetFlow Abstract: The inherent support in routers (SNMP counters or NetFlow) is not sufficient to diagnose performance problems in IP networks, especially for flow-specific problems where the aggregate behavior within a router appears normal. Consistent NetFlow (CNF) architecture is proposed for measuring per-flow performance measurements within routers. CNF proposes hash-based […]


MeasuRouting: A Framework for Routing Assisted Traffic Monitoring

MeasuRouting: A Framework for Routing Assisted Traffic Monitoring Abstract: Monitoring transit traffic at one or more points in a network. This problem is addressed by strategically routing traffic sub-populations over fixed monitors. This approach is MeasuRouting. MeasuRouting works within the constraints of existing intra-domain traffic engineering operations that are geared for efficiently utilizing bandwidth resources, […]
