Therefore, there is a possibility for improving the performance of non-real-time data traffic while still meeting the QoS of service requirement for real-time CBR traffic. The DOCSIS is established as the primary HFC network data communication standard. The intended service allows transparent bi-directional transfer of Internet Protocol traffic between the Cable Modem Termination System in cable system headend and Cable Modem in customer locations with significantly high data rate.

DOCSIS HFC网络的宽带性能使得传输高质量的实时音视频数据成为可能，实时可变比特率视频业务是宽带HFC网络的主要应用之一，实时VBR视频业务具有严格的延时和延时抖动要求，然而当前的DOCSIS HFC网络只能提供高速Internet接入，只支持有限的服务质量保证，现有的协议和方法不适合上行传输实时VBR视频业务。
