The derper sends an in-protocol keepalive every 60-65s, so frequent TCP keepalives are unnecessary. In this tuning TCP keepalives should never occur for a DERP client connection, as they will send an L7 keepalive often enough to always reset the TCP keepalive timer. If however a connection does not receive an ACK promptly it will now be shutdown, which happens sooner than it would with a normal TCP keepalive tuning. This re-tuning reduces the frequency of network traffic from derp to client, reducing battery cost. Updates tailscale/corp#17587 Updates #3363 Signed-off-by: James Tucker <james@tailscale.com> |
