Squeezing Milliseconds: The Impact of TLS 1.3 Handshake Overhead on File Connections

Squeezing Milliseconds: The Impact of TLS 1.3 Handshake Overhead on File Connections featured header illustration

Security is critical for modern internet traffic. Today, over 95% of download links use secure HTTPS (TLS) connections.

However, establishing a TLS handshake requires multiple round trips, introducing latency before the download even begins.

TLS 1.3 Session Resumption

NextGen DLM leverages the latest TLS 1.3 standards. In addition to reducing handshakes to a single round trip, it supports 0-RTT (Zero Round-Trip Time) session resumption.

When establishing our 16 parallel socket connections, the client uses cached session tickets, eliminating handshake latency and launching downloads instantly.
