Nowadays multiple types of services in carriers have made the great challenges in transport bandwidth and network flexibility. The fundamental network

such as OTN

must meet the needs of more services and new applied technologies and also must be suitable of the scenario of upcoming 5 G network

still hot broadband access network

increasing business private line services and etc. Based on the above services and OTN features

this paper first analyzes service types to conclude the bottle necks of existed network planning method. Secondly

the band-new method of network resources allocation

based on SDN and AI

is introduced to solve the planning troubles mentioned above. Finally

through the application of this system

the real local network in some city is showed as an example

to verify the efficiency of data processing

the precision of network simulation

and the value of applying.
