Router Support for Fine-Grained Latency Measurements Abstract: Datacenter network applications, including automated trading and high-performance computing, have stringent end-to-end latency requirements where even microsecond variations may be intolerable. The resulting fine-grained measurement demands cannot be met effectively by existing technologies, such as SNMP, NetFlow, or active probing. Instrumenting routers with a hash-based primitive that we […]

Comments Off on Opportunistic Flow-level Latency Estimation using NetFlow
Posted in: Final year projects
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 […]
