situation, but that's another article. The key to understanding the Zigbee routing algorithm is to understand how both addresses are used. The network source or destination address is what I'll call the absolute source or destination. This means that if a frame originated from address 0x1234, this will be the source address in the networking field no matter what. The same goes for the networking destination. On the other hand, the MAC address is used as a next hop address which could just be a stepping stone on the way to the destination. It's like if I wanted to go to Akihabara. I know where I came from, and where I want to go, but from a microscopic perspective, I have a couple of interim destinations (train platforms) I need to get to before I reach Akihabara. And one more thing about addressing, for the purpose of this series, I'm only going to be referring to the 16-bit short addresses used by the MAC layer. The MAC actually has a 64-bit address as well, but it would just confuse things.
