Optimization and Design of PTN Network Security Structure

分组传送网(Packet Transport Network,PTN)能够兼容多种网络,诸如ATM、SDH、以太网、PDH、PPP/HDLC等,被广泛地应用到各种组网通信,PTN能够有机地结合数据技术和传输技术,使运营商的基础网络优势得到很大程度的提高。目前,分组传送网(PTN)在多网络通讯、传输带宽、流量、信息安全等方面无法满足用户需求,文中设计出新型的PTN网络安全架构,根据业务及流量选择架构类型,并引入融入OTN核心组网和p-Cycle保护算法,通过使用OTN核心组网方案,使汇聚机房带宽和数据传输能力大大提高,具有较强的扩容能力,通过使用p-Cycle保护算法并构建组网拓扑图,提高了PTN网络信息数据传递的安全性能。文中还设计出PTN组网软件架构,便于用户应用、查询。实验表明,设计的方案大大降低了组网难度,提高了网络速度、服务质量,具有较好的网络可扩展性和安全性。

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.
