Abstract: PTN (Packet Transport Network) can be compatible with a variety of networks,such as ATM,SDH,Ethernet,PDH,PPP/HDLC,and is widely used in various networking communications.PTN can organically combine data technology and transmission technology,enabling the operator’s basic network advantages to be greatly improved.At present,PTN cannot meet the needs of users in terms of multi-network communication,transmission bandwidth,traffic and information security.This paper designs a new PTN network security architecture.It selects the architecture type according to service and traffic,and introduces the OTN core networking and p-Cycle protection algorithm.By using the OTN core networking solution,the bandwidth and data transmission capability of the aggregation room is greatly improved.The device has a strong capacity to expand.By using the p-Cycle protection algorithm and building a network topology map,the security performance of PTN network information data transmission is improved.This paper also designs the PTN networking software architecture,which is convenient for users to apply and query.Experiments show that the designed scheme greatly reduces the difficulty of networking,improves network speed and service quality,and has better network scalability and security.
