MustardTree EAR99
MustardTree is XO Defense's multi-path adaptive transport protocol. It evaluates available communication channels — satellite burst, cellular, SMS, acoustic relay, LoRa, BGAN, Wi-Fi — and selects the optimal path based on availability, latency, cost, security posture, and mission priority. When the active channel degrades or fails, MustardTree automatically fails over to the next available transport without operator intervention. The protocol implements PACE planning (Primary, Alternate, Contingency, Emergency) at the software level, removing the requirement for manual channel switching during communication degradation events.
How XO Defense Addresses This
MustardTree is the transport management layer of the XO Defense protocol stack. It abstracts the physical transport from the application layer, allowing all other protocols (Mustard Envelope, Mustard Chain, Queue Burst, P139, SatPay) to operate transport-agnostically. MustardTree handles transport selection, failover, and path optimization automatically. In practice, this means an operator sends a message and MustardTree determines the best available path — if satellite is available, it uses satellite; if denied, it falls to cellular; if cellular is denied, it falls to SMS; and so on through the PACE hierarchy. The operator never needs to manually switch between communication modes.
