In the overlay model , the addressing scheme , the routing protocol and the signaling protocol at the customer layer run independently from those at the transfer layer 在重叠模型中，客户层的地址方案、路由协议和信令协议与传送层的地址方案、路由协议和信令协议各自独立运行。
In the peer model , both the customer and transfer layers use the common control plane and the general multi - protocol label switching ( gmpls ) . since they use the same addressing scheme , routing protocol and signaling protocol , there is no uni protocol 在对等模型中，客户层和传送层采用统一的控制平面，采用通用多协议标签交换（ gmpls ） ，地址方案、路由协议和信令协议相同，因此没有uni协议。
