 ((("architecture, Lightning Network","protocol suite")))((("protocol stack")))The Lightning Network is composed of a complex collection of protocols that run on top of the internet. We can broadly classify these protocols into five distinct layers that make up a _protocol stack_, where each layer builds upon and uses the protocols in the layer below. Also, each protocol layer abstracts the underlying layers and "hides" some of the complexity.
 
-The architecture diagram shown in <<lightning_network_protocol_suite>> provides an overview of these layers and their component protocols.
