Abstract: A method and system are disclosed for reliably distributing file data from a single server to multiple client computers using a cyclical multicast approach. By “cyclical,” it is meant that data is distributed repeatedly onto the network at a certain period. The server transmits metadata asynchronously onto the network via a first communication channel, and file data via a second communication channel. Both data sets are received by one or more client devices operating a data catch module, which listens for metadata and file data from the network via a first and second communication channel. Once the metadata is received, the first channel is disconnected, and the one or more client devices operating the data catch module listen for file data for which the metadata is associated. Any file data not received during one cycle can be received by the client device in a subsequent cycle.
