TEXT | When using an imaging workstations, a user can view images that are linked The network transmission works by sending a message first. During the exchange of message protocol data units, information is exchanged about the [BLOB] that is going to be sent via FTP. The sender indicates that there is a BLOB to send. The receiver replies with the IP address to send the message to and the directory to put it in. The sender then constructs a series of commands that will access the FTP software running on that machine, stores in as a file that can be executed in batch mode and puts an entry MUMPS global to indicate that the file needs to be executed. A background process in MUMPS (XMRTCP), polls this file every few seconds and when it sees an entry, it makes a request to the to a message on a second screen. This works using standard calls to the imaging API to move the appropriate image into the export directory. When the image is in the export directory the aforementioned file is executed and the image is FTP'd to receiver of the message. API of the imaging product. Images are brought off of a file server on the local area network via ethernet and displayed. Network transmissions of messages are performed from a platform that has both NFS capabilities and TCP/IP. Images are delivered off of the file server that is on the local area network into a directory that is mounted via NFS onto this platform, again by a call to the imaging API. The relationships of multimedia [HARDWARE] must be setup correctly. |
