Thus all devices of the protocol can interact. ZigBee ensures that networks remain operable in the conditions of a constantly changing quality between communication nodes. ZigBee standard defines a multilayer structure of software. Usually this is called ZigBee protocol stack. Despite the declared simplicity ZigBee stack is not much simpler than TCP/IP protocol stack for small-class add-in devices.It is very costly to purchase the stack in source texts. The stack is usually offered in the form of compiled libraries, also at high prices.
Because address allotted to the network ID varies, depending on the address. Most IP addresses fall into the following address classes: Class A addresses: The first 8 bits of the IP address are used for the network ID. The final 24 bits are used for the host ID. Class B addresses: The first 16 bits of the IP address are used for the network ID. The final 16 bits are for the host ID. Class C addresses: The first 24 bits of the IP address are used for the network ID. The final 8 bits are for the host ID. Address Class and Network Type. More bits lead to more combinations.
