That approach, of having the network provide only ''unreliable'' [[packet]]s (sometimes called [[datagram]]s) has several huge advantages:

* The network itself is much simpler, because it does not have to go to any extra work to ''guarantee'' that data is not lost. It just does its best (hence another name for the service it provides, 'best effort'), and focuses on its main job - moving data around.

* This approach allows ''all'' the intermediate [[packet switch]]es ([[router]]s) in the overall network to carry ''no'' [[state]] about the [[connection]]s travelling through them. This has been the single biggest reason why the Internet has been able to grow ('scale', in engineering jargon) to the stupendous size it has.

Louis Pouzin is the French computer scientist who made the key technical step in data networking between the ideas of the ARPANET and those of the later Internet. The network that he and his team built, using this new approach, CYCLADES, laid the technical groundwork for the Internet.
