Multi-Instance Transport Mode

Multi-Instance Transport Mode

Depends on: #7 (Single Transport Mode)

Summary

Run multiple transport instances with gost load balancing for higher aggregate bandwidth.

Motivation: Single DNS tunnel has limited bandwidth. Multiple instances can aggregate throughput by distributing connections.

Design

Architecture:

App → gost (load balancer) → Transport Instance 1 → DNS Proxy → Server
                           → Transport Instance 2 → DNS Proxy → Server
                           → Transport Instance N → DNS Proxy → Server

gost features used:

• Selector - distribute connections across instances
• Failure detection - remove dead instances from pool

Configuration:

• Number of instances
• Can mix transport types (e.g., 2x Slipstream + 1x DNSTT)
• Per-instance server config if connecting to different servers

CLI:

dnstc start --instances 3 --transport slipstream --domain t.example.com
