− | + | 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. | |

− | + | ===Main Sequence=== | |
+ | # App GS waits for incoming socket requests. | ||
+ | # App M creates a socket connection to App GS. | ||
+ | # 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. | ||
+ | # App GS checks its RemHostName list for duplicates. (Alt #1) | ||
+ | # App GS sends a RemHostNameSETOK NetMsg to App M. | ||
+ | # App GS sends a RemHostNameSET NetMsg to App M. | ||
+ | # App GS waits for App M to send a RemHostNameSETOK NetMsg. | ||
+ | # App M sends a RemHostNameSETOK NetMsg. | ||
+ | # App M is now connected to the Geometry Service network. | ||
+ | # App M sends a NewSessionREQ NetMsg. | ||
+ | # App GS creates a new Session. | ||
+ | # App GS sends a NewSessionREQOK NetMsg. | ||
+ | |||
+ | ===Alt Sequence #1=== | ||
+ | 6a. App GS finds that the incoming Host is already on the HostList. Either a duplicate name, or a duplicate connection. | ||
+ | 6b. App GS sends App M a RemHostNameSETFAIL NetMsg. | ||
+ | 6c. App GS drops socket connection to App M. | ||
+ | 6d. App M drops socket connection to App GS. | ||
+ | |||
+ | ==Application Request For Geometry== | ||
+ | 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. |
