Defined in:
lib/cosmos/tools/cmd_tlm_server/routers.rb

Overview

Controls the routers as defined in the Command/Telemetry configuration file. Routers are just interfaces which receive command packets from their remote connection and send them out to their interfaces. They receive telemetry packets from their interfaces and send them to their remote connections. This allows them to be intermediaries between an external client and the actual device.
