Internal and External Clock Synchronization in a Power Line Network

Abstract:	The nontrivial problem of distributing time in communication networks is not only limited to the Internet world, where this is nowadays solved by NTP. As the digital divide gap has not only to be closed between the last mile to the end user’s PC and the nearest service point, also other systems like substation automation or energy meter management can benefit from a global notion of time as a service. As the usual high-performance Ethernet is, for the simple cost reasons of the cabling, not the most promising candidate to reach such nodes, other technologies such as power lines have to be investigated. This paper proposes a hierarchical clock synchronization scheme for power line networks.
