Architecture Map

This page explains how the major MOSH subsystems relate to one another.

MOSH describes what the node wants to do.

IMC describes how MOSH hands that intent to a communication carrier.

MTRP describes how packets are routed, forwarded, and delivered across one or more transports.

The transport layer describes how bytes move over a specific link.

A typical message path looks like this:

1. MOSH creates or requests an action
2. IMC hands that action to a carrier
3. the carrier uses MTRP to route or deliver the message
4. MTRP selects a path and uses a transport
5. the receiving side processes the message and returns it upward

MOSH and MTRP solve different problems.

• MOSH is application behavior
• MTRP is network behavior

IMC exists so those layers can evolve without being tightly coupled.

This structure allows:

• MOSH logic to remain transport-independent
• multiple transport backends to exist under one routing model
• constrained and full-capability nodes to participate in one system
• bridge nodes to connect different transport classes

• MOSH Architecture
• Carrier Model
• MTRP Protocol
• Supported Platforms
