Conclusion
Sessionless networks can be really handy when you're just passing short messages
around and don't need a lot of acknowledgment. They involve a lot less work because
you don't have to maintain the connection. They also give you a lot more freedom
in how many devices you want to address at once.
By comparing the two projects in this chapter, you can
see there's not a lot of work to be done to switch from
directed messages and broadcast messages when you're
making a sessionless network. It's best to default to directed
messages when you can, which reduces the traffic for
those devices that don't need to get every message.
Now that you've got a good grasp of both session-based
and sessionless networks, the next chapters switch
direction slightly, covering two other activities of connecting
networks to the physical world: location and identification.
