MTRP is a lightweight multi-transport routing protocol intended for resource-constrained embedded systems and MOSH-class nodes.

MTRP is designed to:

• provide a common routing layer across heterogeneous transports
• support direct-neighbor and multi-hop forwarding behavior
• operate within constrained RAM and flash budgets
• favor explicit and inspectable state over opaque internal behavior

The current documented scope of MTRP includes:

• neighbor discovery
• route advertisement and learning
• forwarding table maintenance
• route selection policy
• send-time preferred-route selection
• support for compact operation on constrained transports
