Concepts

There are several layers that enable lightyear to act as a games networking library. Let's list them from the bottom up (closer to the wire):

• transport: how do you send/receive unreliable-unordered packets on the network (UDP, QUIC, etc.)
• connection: abstraction of a stateful connection between two peers
• channels/reliability: how do you add ordering and reliability to packets
• replication: how do you replicate components between the client and server
• advanced replication: prediction, interpolation, etc.
