Abstract

Systems and methods are provided for efficient communication through a fabric network of devices in a home environment or similar environment. For example, an electronic device may efficiently control communication to balance power and reliability concerns, may efficiently communicate messages to certain preferred networks by analyzing Internet Protocol version 6 (IPv6) packet headers that use an Extended Unique Local Address (EULA), may efficiently communicate software updates and status reports throughout a fabric network, and/or may easily and efficiently join a fabric network.
