Grapple is a high level network layer. It's designed to remove the hard work from making applications multiuser and to allow the addition of multiplayer features to a game for as little as a dozen lines of code. However while also remaining fully featured, so if you want more from your networking, you can have it.[1]
Development started in 2006 by Michael Simms from Linux Game Publishing LTD and is released under the GNU LGPL.
Grapple supports simple development of networked applications using both TCP/IP and UDP/IP. Grapple keeps track of connections to a server, relays messages from client to client, all without the need to understand any complicated network code.
[edit] Features
The features grapple supports at this time is:
- Simple client-server networking
- Keeps all clients aware of all other clients
- Network messenging by either a push or a pull model, or a mixture of both
- Unlimited connections to multiple servers.
- Multiple methods of querying users
- Data transfer via TCP, UDP, or reliable UDP
- Passworded servers
- User Groups for client bandwidth saving
- Server security - server can disconnect any client
- Network load reacting data transmission and retransmission
- Background pinging to monitor network states
- A fully functional lobby system
- Server failover
- NAT traversal using STUN
