Abstract
A method and device for delivering multimedia data using IETF QoS protocols. MPEG media data can be transmitted in packet units through a network using the IETF QoS protocol by mapping MPEG media traffic factors onto IETF QoS traffic factors. By encoding or transcoding MPEG media traffic according to a double leaky bucket model indicated by the four factors, a maximum bit rate, a first buffer size, a guaranteed bit rate, and a second buffer size, the MPEG media traffic factors may be transmitted using the IETF QoS protocol without having to go through the process of being mapped onto QoS traffic factors.
