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 sampling to ensure that two adjacent routers record the same flows.
