 ==== Lightning Network Transport and Routing
 
-((("Lightning Network", "transport and routing")))All communications between LN nodes are encrypted point-to-point.

 Whenever a node wishes to send a payment to another node, it must first construct a _path_ through the network by connecting payment channels with sufficient capacity. Nodes advertise routing information, including what channels they have open, how much capacity each channel has, and what fees they charge to route payments. The routing information can be shared in a variety of ways and different routing protocols are likely to emerge as Lightning Network technology advances. Some Lightning Network implementations use the IRC protocol as a convenient mechanism for nodes to announce routing information. Another implementation of route discovery uses a P2P model where nodes propagate channel announcements to their peers, in a "flooding" model, similar to how bitcoin propagates transactions. Future plans include a proposal called http://bitfury.com/content/5-white-papers-research/whitepaper_flare_an_approach_to_routing_in_lightning_network_7_7_2016.pdf[Flare], which is a hybrid routing model with local node "neighborhoods" and longer-range beacon nodes.
