System & Network Architecture Diagrams

A printable companion to the AETHER specification. ASCII diagrams are intentionally text-based so they render cleanly in PDF, on paper, and inside academic submission portals.

3. Multi-path routing topology

                    [SRC]
                   /  |  \
                  /   |   \
              hop1a  hop1b  hop1c
               |  \   |     /
               |   \  |    /
              hop2a  hop2b
                  \   |
                   \  |
                    [DST]

Each packet is forwarded along top-K paths weighted by softmax(score).
Lost-link reroute uses pre-computed backup arcs (sub-second).

4. Layered radio stack

Layer	Range	Use case	Power profile
BLE / UWB	0–30 m	Personal / proximity	Ultra-low
Wi-Fi Direct / 6E	30–250 m	Urban density	Low–medium
LoRa / Sub-GHz	1–15 km	Rural & telemetry	Low
Drone / vehicle relays	5–50 km	Mobile gap bridging	Variable
LEO satellite fallback	Global	Last-resort uplink	High
