C2 Router Switch TSM SATCOM As a “vertical” stack that provides the complete means for end-devices to communicate down to transport layer systems (e.g., through MODEM’s, gateways). This “system” is a type of dynamic or ad-hoc system, e.g., dynamic routing Within device-compatible “networks”, e.g., EPRLS. A network is a type of system in DM2 because it is a bunch of systems working together.
