Title of the Talk: Network Latency: Measuring Network Speed at Billion-Event Scale in an Encrypted World

Abstract:

Modern encryption protocols have rendered traditional content-inspection and probe-based latency measurement increasingly ineffective. DNS Hybrid Latency (U.S. Patent No : 11,245,606) addresses this by passively deriving one-way latency from the temporal gap between DNS resolution and transport-layer handshake initiation at the network gateway – requiring no traffic decryption, synthetic probes, or instrumented endpoints.

Operating at billion-event scale across large mobile infrastructure, the method achieves app-level latency attribution by cross-correlating DNS query targets with connection-layer timestamps – a granularity unavailable to contents-based approaches as encryption expands. The architecture is protocol-agnostic and transport-invariant, applicable across mobile, fixed broadband, and enterprise network segments.
