Application and Development of PTN Technology

Yang Zhang


The packet transmission network (PTN) technology, which combines the advantages of packet technology and
synchronous digital system (SDH) technology, is more suitable for multi-service bearer and exchange, and satisfi es
fl exible network scheduling and multi-service transmission. It can provide network protection function. PTN technical
characteristics determine that he can better use the existing network, can provide more with the current network
interface. This paper analyzes the characteristics of PTN technology and the existing networking methods, and
proposes a network improvement method of IP + PON + PTN.
