PEOTN is the further integration of the packet and optical transport technology, which is the mainstream technology to deal with the transmission network development trend of large capacity, packet, intel igence in the future. It briefly introduces the current technical situation and equipment of PEOTN, and then introduces the local communication net infrastructure layout, how to realize the business of comprehensive carrying based on the existing multiple transmission network, and its evolution direction in the future. Taking one local network as example, it explains the calculation method of network model of PEOTN. It mainly introduces PEOTN network application in the core layer, convergence layer and access layer, based on the communica-tion net infrastructure.
