One of the ideas of tcp checkpoint restore, at least for me, is to avoid a round-trip delay when restoring the connection. Wouldn't a key renegotiation cause at least one round-trip? I'm probably being dense here...
- remram 5y agoIt probably would yes, though that might still be fewer round-trips than establishing a new TLS connection.
- touisteur 4y agoYoure right. I'd actually be really interested in a write-up on such ideas. SSH, TLS or wireguard (voluntary) 'takeover' or Checkpoint&Restore. I don't remember whether QUIC had multihoming (might help with checkpoint restore) but since most APIs are in userland and it's udp it might be faaar easier.
