U2BB(Ubiquitous Ultra Broadband), the future-oriented architecture of communication network, it can support the ubiquitous 20-100M internet access end to end, and have the ability of long-term evolution. The traditional network was designed based on 1-4M access, and mainly for triple play, while the OTT and cloud computing application developed rapidly in recent years, the broadband access have to reach 20-100M to fulfill the basic requirement of people, and corresponding traffic will grow more than 100 times in next 5 years. With current architecture, the cost of upgrade of network increased fast,while the reliability reduced as more and more complicated network, obviously, the current architecture can not support coming ubiquitous ultra-broadband era. The U2BB is characterized by the following fundamental aspects: * Any media access(Fiber,Cooper,Cable,etc) * 20-100M bandwidth for each terminal. * Flexible and intelligent adapting to business and service change. * QoS assurance for IP Video end to end. :
