| + | Initial handshake: |
| − | This sequence of NetMsg exchanges represents the communications between an external application (App M) attempting to connect to a running Geometry Service (App GS). This sequence assumes success.
| + | * Server sends [GS Remote Nodename Set] |
| | + | * Client sends [GS Remote Nodename Set] |
| | + | * Client sends [NewSessionReqMsg] (login/passwd) |
| | + | * Server sends [SessionInfoMsg] (uuid of session) |

| − | # App GS waits for incoming socket requests.

| − | # App GS accepts the socket connection.

| − | # App M and App GS are now connected at the socket level.

| − | # App M sends a RemHostNameSET NetMsg to App GS.

| − | 6a. App GS finds that the incoming Host is already on the HostList. Either a duplicate name, or a duplicate connection.

| |
| − | This sequence of NetMsg exchanges represents the communications between an external application (App M) as it requests Geometry from the Geometry Service (App GS). This sequence assumes success.
