光传送网中多厂商设备PCE互联互通方案研究

In the construction of intelligent optical network the ASON/OTN equipment is widely used.The full commissioning of the intelligent control plane dramatically increased the network scheduling ability and survivability.Usually the equipment belongs to different vendors and because of the independent development it can't achieve the control plane and management plane interworking. It's still unable to solve the existing problems within the whole network, in particular, the problem of unified managements and administrations.These problems have become increasingly prominent with the construction of networks, so it is particularly important to solve the interconnection problems between different vendors'devices and between different domains.This paper proposed a multi-vendor interconnection scheme based on PCE. The main idea is to connect the software platform with the hardware control plane directly through a network cable. Through the format conversion of signaling message packets on the software platform, the physical node device can identify the message packets to realize the internetworking between the hardware and the software platform.
