| This protocol is UDP and bi-directional. It can be thought of as another layer within an application's network layer. [[Subgame]], [[ASSS]], [[Continuum]], VIE's [[SubSpace]] client, the [[Directory server]], and the [[Billing Server]] utilize this protocol, though [[Grelminar]] has designed a TCP Billing Server protocol.

| *The maximum packet size is 520 bytes
| |
| *All integers are little endian
| |
| *All core packets begin with the type byte 0x00
