- * => communicators use selective ACKs for flow control
- * => transport uses message-level ACKs for RTT, fragment confirmation
- * => integrate DV into transport, use neither core nor communicators
- * but rather give communicators transport-encapsulated messages
- * (which could be core-data, background-channel traffic, or
- * transport-to-transport traffic)
