Abstract: A novel method, called DPDP(default path and dedicated path)is introduced and an experiment is carried out to demonstrate the possibilities and rationality of node design, working process and corresponding communication protocol implemented by DPDP. The problems related with DPDP are also discussed at last.

摘要： 设计了一种新的骨干网中实现IP波长路由的方法，称为DPDP(缺省波长和专用波长)，设计实验验证了节点结构设计、工作流程和相应通信协议设计的合理性，最后对相关问题进行了讨论。
