多重业务的宽带承载

多重业务的迅速发展和其拥有的多媒体、互动等新特征，使宽带网络难以有效地实现统一承载，并进而成为多重业务发展的障碍。要实现在宽带网络中可运营、可管理、可增值地承载多重业务，需要全面采用新技术。在各种新技术中，高宽带的网络技术使网络资源更丰富；服务质量（QoS）技术实现多重业务的差异化服务，从而保证业务的服务质量；强大的组播技术有效地控制和保障多媒体业务的开展；安全保障技术为多重业务提供高质量、完善的安全运营机制；高可靠性技术为宽带网络承载多重业务提供可靠、不间断地运营机制。

Technologies for Broadband Network to Bear Multi-play Services

With the rapid development of multi-play services with new characteristics like multimedia and interactivity, it is difficult for the present broadband networks to carry them effectively. The bearer has become a bottleneck for the further development of multi-play services. All-around new technologies are necessary to be used in the broadband network for its operable, manageable and value addable bearing of multi-play services. The network technologies for broad bandwidth help enrich network resources. QoS technologies guarantee QoS by implementing differentiated services. Powerful multicast technologies effectively control and guarantee applications of multimedia services. Security technologies provide a high quality and perfect security operation system for multi-play services. High reliability technologies provide a reliable and uninterrupted operation system for the broadband network to bear multi-play services.
