====== MTRP ======

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

===== Goals =====

  * 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.

===== Current Scope =====

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

===== Core Concepts =====

  * ''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
