The rapidly developing multi-play services, with new features as multimedia and interaction, create a difficult task for the present broadband networks to carry them effectively. Complete new technologies must be adopted, as the bearer became a constriction factor of the further development of multi-play services. These new technologies will make the bearer effective to be able to operate, manage and add value to multi-play services over the broadband networks. Among all new technologies, the high-bandwidth network technologies enrich network resources; QoS technologies guarantee QoS by implementing differentiated services; powerful multicast technologies effectively control and guarantee the deployment of multimedia services; security guarantee technologies provide a high-quality and perfect security operation system for multi-play services, and high-reliability technologies provide a reliable and uninterrupted operation system for the broadband network to carry multi-play services.
