Planning of OTN and PTN Transmission Networks in Electric Communication Network
With the continuous development of network services,SDH devices in power communication networks have be-come inadequate for the demand on high bandwidth and IP.To solve this problem,this essay puts forward the planning of joint construction of networks using OTN and PTN equipment.According to the different needs of cities with various geo-graphical locations,three kinds of networking schemes are proposed,in which the scheme using OTN to form aggregation layer and core layer and using PTN to form access layer through the aggregation node after the access ring decentralized aggregation,has the highest generalization and is suitable for most cities.
