All ZigBee networks require a coordinator, which is responsible for NETWORK formation. In ZigBee 1.0 and in ‘ZigBee’ stack profile, the coordinator ADDITIONALLY hosts the binding table and this way BECOMES a weak POINT. Mechanisms to deal with coordinator breakdowns (such as duplication of the binding table) are IMPLEMENTATION issues and out of the scope of revision 1.0.

ZigBee 1.1 will host mechanisms to deal with coordinator failures and manage decentralized binding tables. The coordinator will not be any more at risk of becoming a single point of failure.
