当前基于 MPLS-TP(多协议标签交换-传送架构)的光网络普遍存在网络动态变化并且不能充分感知上层业务的多样化需求的问题。针对这个问题，文章提出了一种基于多维感知的信令机制。该机制充分利用业务感知技术和网络感知技术，以期实现光网络对上层业务多样化的支持能力。仿真结果验证了该机制的有效性，证明该机制降低了业务连接建立时的冲突率和时延，提高了光网络的光路分配与业务需求之间的匹配效率。

There commonly exist dynamic variations in current MPLS-TP-based optical networks,which cannot be fully aware of the diversified demands for upper-level services.To solve this problem,this article proposes a multi-dimensional perception-based signaling mechanism,which makes full use of the service perception technology and network awareness technology in or-der to realize the network supporting capability for upper-level service diversification.Simulation results verify the effectiveness of this mechanism as it reduces the collision rate and time delay in service connection establishment and enhances the efficient matching between the light-path allotment and service requirements.
