In 3G, ATM will be replaced by AllIP, which is determined by the superiority of the All-IP technology and interfaces, the All-IP interface protocol stack is different from IPoA. The All-IP protocol features higher efficiency and easier networking. In terms of internal architecture, All-IP is also quite different from ATM. The internal architecture of All-IP shows obvious superiority in its throughput, industrialization and networking flexibility. CDMA2000 of ZTE is a real All-IP product, as it externally provides All-IP interfaces as well as the traditional interfaces; while internally, since it is based on the All-IP switching architecture, it is in a position to better and faster construct customeroriented large-capacity networks.
