MiniUDP: A Simple UDP Layer for Shipping and Receiving Byte Arrays

Alexander Shoulson, Ph.D. - http://ashoulson.com

Based loosely on MassiveNet, and LiteNetLib.

Supported Networking Tasks:

• UDP traffic I/O for byte[] arrays with very little overhead
• Connection establishment and time-out detection
• Reliable-ordered and unreliable-sequenced message channels
• Traffic statistic collection for ping, remote/local packet loss, and remote/local packet drop
• Noise-based bidirectional latency and loss simulation with configurable parameters

Three delivery modes:

• Connection Token: A custom string attached with an opening connection request. Will be delivered to the host when the connection is established and made available via an event. Intended for session token authorization.
• Payloads: Sent immediately upon request as unreliable-sequenced. MiniUDP will not re-send but will drop payloads on arrival if they're older than the latest. Intended for synchronizing delta-encoded game state data.
• Notifications: Queued and sent at regular intervals as reliable-ordered. MiniUDP will ensure the arrival of these messages and will re-send if necessary. Intended for extra-game messages like chat, authentication, and other bookkeeping tasks.

Wishlist:

• Encryption and authentication

Not Supported:

• Fragmentation/reassembly (MiniUDP enforces a hard MTU for its payload size)
• Data serialization (MiniUDP expects a byte[] array and int length for all data)
• RPCs
