However , in case of video or other bandwidth intensive media, the master arranges for all slave servers to send data in a synchronized fashion. The master server also maintains a one to many control connection to all the slaves, over which it sends control commands received from the client, and any other commands required for correct operation of the httpd server. The central manager handles client requests, dispatches data file requests to storage nodes, and coordinates multimedia stream transmission from storage nodes.
