一、融合趋势融合将成为下一代通信技术发展的“主旋律”。随着网络应用加速向IP汇聚,网络将逐渐向着对IP业务最佳的分组化网的方向演进和融合。下一代网络将是电信网与因特网的融合和发展。融合将体现在“话音与数据”、“传输与交换”、“电路与分组”、“有线与无线”、“移动与WLAN”、“管理与控制”、“电信与计算机”、“集中与分布”、“电域与光域”等多个方面。二、交换技术从电路到分组随着业务从话音向数据的转移,从传统的电路交换技 First, the convergence of converging trends will become the “main theme” of the next generation of communications technologies. As network applications accelerate converging to IP, the network will gradually evolve and converge in the direction of the best packet network for IP services. Next-generation networks will be the convergence and development of telecommunications networks and the Internet. The convergence will be reflected in the “voice and data”, “transmission and exchange”, “circuit and packet”, “wired and wireless”, “mobile and WLAN”, “management and control ”,“ Telecommunications and computer ”, “ concentration and distribution ”, “ electric domain and light domain ”and other aspects. Second, the exchange of technology from the circuit to the packet As the business from voice to data transfer, from the traditional circuit-switching technology
