Links and sessions

How encrypted links turn a destination into a reliable session for requests and transfers.

Why open a link

Why open a link

Single packets are enough for simple messages. Links add a cheap encrypted channel with forward secrecy, RTT tracking, keepalives, and helpers for requests, channels, buffers, and file resources.

  • Link setup costs only a few packets once a path exists
  • Initiator anonymity still applies for the described link modes
  • Resources and channels ride on top of an established link
