What To Do Instead
New application protocols that don’t rely on in-order delivery of byte streams.
New bundle-oriented protocols at the transport and network layers.
- Store-and-forward operation.
- Concurrent transmission, out-of-order delivery.
New reliable link layer protocol.
- Point-to-point retransmission over interplanetary distances.
- Sub-layer of underlying CCSDS protocols for coding and forward error correction, to minimize the need for retransmission.
