RFC: Robust stable connection. #8
Description
Now stable has two connect type.
- Direct (EndpointStream) - listen the transport's stream. like Tcpstream.
- Relay (SessionSend) - use other session's channel address as endpoint.
If listen, need handle two way.
- build stable connection table, add other connect type and keep stable connect the remote peer. (by relay).
- If current connection is lost, use other channel to it. and then rebuild stable connection table.
If lost connection.
- If now is Directly, reconnect. (if not ok, change to Relay way.).
- If now is Relay, if relay session is closed, choose other closest peer in DHT and send Ping to check.
