MTRP

MTRP is a lightweight multi-transport routing protocol for MOSH-class embedded nodes.

• Support small embedded nodes with limited RAM and flash.
• Allow multiple transport backends under one routing layer.
• Prefer simple, explainable behavior over hidden complexity.
• Scale from direct-neighbor messaging to multi-hop forwarding.

MTRP currently includes:

• neighbor discovery
• learned route advertisement
• forwarding table maintenance
• route-selection policy behavior
• preferred-route tracking at send time
• compact-header support for constrained transports

• Neighbor table: direct peers heard on a local transport
• Forwarding table: learned route candidates for destinations
• Preferred route table: route choices actually selected during forwarding
• Path: a registered transport instance
• Metric: lower is better
