Data Throughput*
RR = router to router,
RE = router to end device (non-sleeping),
ER = end device (non-sleeping) to router,
SE = security enabled.
4 hops = 5 nodes total, 3 intermediate router nodes
* Data throughput measurements were made setting the serial interface rate to 115200 bps, and
measuring the time to send 100,000 bytes from source to destination. During the test, no route
discoveries or failures occurred.
ZDO Transmissions
ZigBee defines a ZigBee Device Objects layer (ZDO) that can provide device and service discovery
and network management capabilities. This layer is described below.
ZigBee Device Objects (ZDO)
The ZigBee Device Objects (ZDO) is supported to some extent on all ZigBee devices. The ZDO is
an endpoint that implements services described in the ZigBee Device Profile in the ZigBee
specification. Each service has an assigned cluster ID, and most service requests have an
associated response. The following table describes some common ZDO services.
