This protocol is UDP and bi-directional. It can be thought of as another layer within an application's network layer.
There is support for reliable ordered packets, large packets and cluster packets.
- The maximum packet size is 520 bytes
- All integers are little endian
- All core packets begin with the type byte 0x00
