A Self-Aware Security Mechanism Based on PTN ECMP Network

This paper presents a generic self-aware solution to guarantee the security of PTN network on ECMP condition. This mechanism, called OAM detection and multipath switching (ODMS) has two points. The first one is sending specific OAM packets periodical to detect out of order status of data flow. The second is switching the routing paths in variable periods according to the flow’s out of order proportion and security level. The mathematical analysis and simulation results both show ODMS’ good performance on guaranteeing the network’s security and quality of services. And ODMS can be widely used in the next generation ECMP-based PTN network.
