摘　　要：近年来,随着互联网的迅速发展,IP业务呈现出爆炸式的增长。由于IP业务自身所具有的特点(如自相似性、收发数据不对称性等),对于承载光网络来说,下一步不仅仅要提高传输链路的带宽和容量,还需要提高光网络的智能性,以满足IP业务对信息传输和交换系统的要求。从下一代光网络的发展趋势入手,分析了两种向下一代光网络演进的模型,并对下一代光网络中引入的关键部分MPLS/GMPLS控制平面作了介绍,在文章的最后对全文进行了总结。Rece n tly, with the development of Internet rapidly, IP services have been taking on t he sense of volatile improvement. Because of the self character of IP services, such as self comparability and asymmetry, the development of optical network w hich transfers the IP services focus on not only the bandwidth and capacity of l inks of transmission, but also the enhancement of network's intelligence. This paper starts with the direction of the optical network development, analyses tw o models evolving into the next generation optical network, and introduces the k ey component of next optical network MPLS/GMPLS. At last, the author summarizes this paper.
