Abstract
A method and system for data delivery from a server to a client is provided. The server maintains a session counter and transmits data to a client at a transmission speed. The server receives a message from the client indicating a percentage of packets lost in a current session and compares the percentage of packets lost to a predefined range of packet loss, and modifies the transmission speed based on the comparison. Forward Error Correction (FEC) may be used to reconstruct the lost packets.
