摘　　要：网络技术的不断发展,促使交换网和传送网技术、结构、功能彼此渗透、不断融合,这就需要在光网络中实现灵活高效的智能控制,在接入平台上提供丰富快捷的接入手段。多业务传输平台(M STP)和自动交换光网络(ASO N)分别代表了不同层次网络边缘设备的融合和传送网的智能化发展趋势,有效整合这些技术,形成智能化的M STP技术,可满足未来网络发展的需要。文章讨论了智能化的M STP设备的构造模型对等模型和重叠模型,并给出了一个为满足数据和多媒体业务的带宽动态变化需求,利用自动连接功能和链路容量调整(LCAS)协议动态带宽分配的解决方案。With the development of network technologies, the switch network and the transport network are penetrating each other in respects of technology, architecture and functionality and gradually evolving towards convergence, which requires flexible and effective smart-control in the optical network and diversified quick access methods at the access platform. The Multi-Service Transport Platform （MSTP） and the Automatically Switched Optical Network （ASON） respectively represents the convergence of network edge equipment at different layers and the intelligentized development of transport networks. The integration of these technologies can intelligentize the MSTP associated technologies in order to satisfy the requirements of network development in the future. In the paper, two structure models of intelligent MSTP, i.e., the peer-to-peer model and the client-server model, are presented and analyzed. A solution to dynamic bandwidth allocation, by using the automatic connection function and the Link Capacity Adjustment Scheme （LCAS） protocol, is also provided, which can meet the demands of dynamic bandwidth requirements for data and multimedia services.
