Remote Power Control and Monitoring of Cross-Platform Devices Using Magic Packets Across Network Boundaries

This paper compares online device discovery and remote startup and shutdown solutions for an enterprise network. As some of for these solutions do only work in a local network and the enterprise network consists of several subnetworks with different firewalls setting, a concept to communicate securely across subnetworks is required. For an evaluation, a prototype is implemented using Wake-on-Lan for startup, Address Resolution Protocol for online detection and Secure Shell for shutting down. Bridged MQTT-brokers are used to communicate across subnetwork with a service in every subnetwork. The central hosted prototype is able to switch on or off computers remotely in every subnetwork.
