The Geometry Service Network (GSNet) Protocol is a TCP/IP based protocol designed to facilitate socketed communications between Geometry Service Nodes on a network. A Geometry Service Node is defined as any softwares that supports communication via the GSNet Protocol.

GSNet Msg Description[edit]
Header[edit]
The header of the GSNet Msg contains the information necessary for quickly determining authenticity, type and length. Geometry Service's network library, libNetwork, has a header byte layout that looks like this:
| Element | Length | Value |
| MsgType | int16 (2 bytes) | |
| MessageLength | int32 (4 bytes) | Does *NOT* include the type or length, so is packet size - 6 |
| MessageUUID | String (Variable bytes) | |
| HasRegardingUUID | Boolean (1 byte) | |
| RegardingMessageUUID | String (Variable bytes) |
- MsgType: 2 byte integer value that tells what type of message this is.
- MessageUUID: Standard UUID for this message. Currently stored as a string.
- HasRegardingUUID: Boolean flag that indicates whether there is a Regarding UUID or not.
- RegardingMessageUUID: Standard UUID that indicates this NetMsg is a response to another NetMsg.
Data[edit]
The Data load of a NetMsg is, obivously, the important and unique part. Data Loads can be as small as zero (in the case of a TypeOnlyMsg) or many kilobytes long.
Here is a list of NetMsg types and here is a list of Common NetMsg Exchanges.
