摘要：
A mechanism is provided for providing reliable redundant data communications. The mechanism issues a request for data to a set of powered elements using a set of secondary communication channels in response to a reduction in a level of communications being detected. The set of secondary communication channels comprises one or more alternating current power lines and the request is sent as data injected onto the alternating current power lines to the set of powered elements. The mechanism receives the data using the set of secondary communication channels from the set of powered elements, analyzes the data to determine a set of recovery actions to restore the level of communications, and issues the set of recovery actions to the set of powered elements using the set of secondary communication channels.
