Abstract:
1. In a computing system where a media file resides within a network file server and the media file is accessed remotely by a first application via a data network, a non-transitory computer-readable storage medium including instructions that, when executed by a computing device, cause the computing device to request notification when the media file is accessed by performing the steps: receiving a first notification registration request at an intermediate node from a first upstream device for a media file residing within a network file server, wherein the first notification registration request includes a first file descriptor for uniquely identifying the media file within the file server; registering the first notification request that specifies the first file descriptor for uniquely identifying the media file within the file server; transmitting the first notification request to a downstream device via the data network; wherein the downstream device is configured to receive the first notification request and to transmit a notification message based on the notification request in response to an access being performed on the media file; receiving a second notification registration request at the intermediate node from a second upstream device for the media file residing within the network file server, wherein the second notification registration request includes a second file descriptor for uniquely identifying the media file within the file server; determining that the second file descriptor is the same as the first file descriptor; and updating the registered first notification request to transmit the notification message received from the downstream device to the first upstream device and the second upstream device in response to an access being performed on the media file.
