Abstract
Systems and techniques are provided for using a multi-threshold buffer model to smooth data transmission to a client. A client to receive data such as streaming media data may include a buffer. A server to transmit data to the client may transmit the data to the client at a first server transmission rate. The client buffer level may be determined at different times; for example, a first buffer level may be determined at a first time and a second buffer level may be determined at a second time. If the buffer level is at a threshold level or has passed a threshold level between the first and second times, server transmission rate information may be determined and may be sent to the server.
