摘　　要：MPLS技术的发展和全光网络核心技术的突飞猛进产生了一种更紧凑的 IP/DWDM集成方案 MPλS.它综合了 MPLS控制能力和光交换机的大容量交换传输优势 ,允许业务层通过现有的控制平面动态地向传输层申请带宽 .文中首先介绍了 MPλS网络结构 ,随后详细分析了 MPλS路由和波长分配方案 ,讨论了 MPλS局限性和相关协议及扩展的The development of Multiprotocol Label Switching technology and the rapid advance of core technology all optical networking produce a sort of even more tight Internet Protocol over Dense Wavelength Division Multiplexing integrated scheme :Multiprotocol Lambda Switching. It combines the advantage of controlling capability of MPLS and large capacity switching and transmitting of optical switching device. It allows the service layer to dynamically apply to transmission layer for bandwidth through the existing control plane. First, this article introduces MPλS network structure ,then labors MPλS routing and wavelength distributing scheme and discusses the limitation of MPλS and its related protocol including the extended GMPLS technology.
