Abstract
A semi-reliable multicast transport protocol uses multiple channels for communication between a server and multiple client devices. A join channel allows the sever to negotiate with client devices to join and exit a transmission session. A communication channel allows the server to communicate with client devices about a status of the transmission session. A polling channel initiated by a content transfer protocol, which runs on top of the transport protocol, transmits polling queries received from the content transfer protocol, receives client device responses to the polling queries, and passes the client device responses to the content transfer protocol. A data channel transmits data to client devices over a network.
