MediaNetwork Data Flow
29
The typical MediaNetwork editing client data flow consists of the following
steps:
1. The MediaNetwork client issues a request to the File Manager through the
MEDIASwitch 16-4G.
2. The File Manager locates the requested file in its cached copy of the file
system metadata and sends the file’s location to the MediaNetwork client.
3. Using the location information it received from the File Manager, the
client retrieves the data from the drive set through the MEDIASwitch 16-
4G.
All requests and responses between the MediaNetwork editing clients and the
File Manager are handled through a messaging mechanism:
• When a client makes a request, the request is stored as a message on the
File Manager. The File Manager polls for request messages at regular
intervals.
• When the File Manager finds a request, it processes a response and stores
it as a message.
• MediaNetwork clients poll for response messages and retrieve the
message information accordingly. Unlike the File Manager,
MediaNetwork clients poll only when they are expecting responses. The
entire process for data retrieval to begin takes less than 1 second.
