Experiment: making VPN sessions survive relay and transport failure
Hi all,
I've been experimenting with a networking idea that treats the session as the stable identity rather than the transport.
Traditional VPNs bind connection identity to a tunnel or socket. If the transport breaks, the connection usually resets.
In this prototype I'm exploring a different model:
connection = session identity
transport = replaceable attachment
The goal is to see whether session continuity can survive events like:
• relay failure
• path switching
• NAT rebinding
• transport migration
Current prototype includes:
• session runtime with deterministic state machine
• transport abstraction layer
• relay forwarding experiments
• session migration demo
• multi-hop prototype (client → relay → relay → server)
Example flow:
SESSION CREATED
client → relay1 → server
relay1 failure
RELAY SWITCH
client → relay3 → server
SESSION SURVIVES
This is still a research prototype (not production).

I'm curious what networking / distributed systems engineers think about a session-centric model vs tunnel-centric VPNs.
Would love to hear criticism or ideas.
