Router Support for Fine-Grained Latency Measurements
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 […]
