ABSTRACT:
Striped Multiplexing Download Queue software facilitates and increases throughput for client-server downloads through a limited communication device. In the “DS Download Station” application, this is used to queue many requests and to broadcast download segments to requesters seeking the same data. This works by employing a “download stripe” on both the server and client. The download stripe on the server side tracks acknowledgements from clients per download segment. On the client side, the stripe tracks received segments to account for duplicate data. Requesters are queued on a first-come first-serve basis. Requesters in the queue may receive segments of downloads while waiting in queue, if the client at the front of the queue is downloading the same file. This recursively saves waiting time for clients in the queue.
