* TODO:
* Implement next:
* - add (more) logging
- * - change transport-core API to specify transmission preferences (latency,
- * reliability, etc.) per message!
+ * - realize transport-to-transport flow control (needed in case
+ * communicators do not offer flow control). Note that we may not
+ * want to simply delay the ACKs as that may cause unnecessary
+ * re-transmissions. => Introduce proper flow and congestion window(s)!
* - review retransmission logic, right now there is no smartness there!
* => congestion control, flow control, etc [PERFORMANCE-BASICS]
