摘要
IP与光技术的融合要求底层光网络具有高度的灵活性和可扩展性，产生了全新的ASON（自动交换光网络），智能OXC（光交叉连接）设备是ASON中的最关键的设备。文中简单介绍了智能自动交换光网络的概念、网络结构，详细分析了ASON中智能OXC矩阵硬件结构和OXC控制平面信令路由功能，最后讨论了智能OXC相关协议及扩展的GMPLS技术。智能OXC强大的光交换能力结合智能信息路由协议，必将与现有网络融合向全智能光网络发展。
The syncretizing of IP with optical technology requests the optical network layer to own high agility and expansibility. A fire new automatic switched optical network(ASON) comes into being. Intelligent optical cross connection(OXC)is the key equipment. This paper first introduces the conception, international standardization status in quo and structure of automatic switched optical network simply, then analyzes the intelligent OXC matrix hardware structure and signaling routing function of intelligent OXC controlling plane in ASON, finally discusses the relative protocol and GMPLS technology of intelligent OXC. The combination of intelligent OXC mighty optical switching capability and intelligent information routing protocol must syncretize with existed network tightly and develop to all intelligent optical network.
