Dedicated enterprise and cloud circuits, data center interconnects and branch links promise bandwidth, delay, loss and availability, but experience depends on more than bandwidth. RFC 6349 notes that L2/L3 tests alone do not fully represent end-user experience: TCP throughput also depends on RTT, bottleneck bandwidth, buffers, loss and windows. Acceptance and routine checks should therefore assess consistent application quality, not just provisioned bandwidth.
BestPerf actively probes and schedules measurements without waiting for user complaints. It records RTT, directional loss, jitter, micro-outages, TCP goodput and quality under load. Flow Hunter can remain passively connected to critical links for SLA monitoring, session anomalies, protocol-stage observations and retrospective analysis, linking trends to real sessions.
