Yang Zhang · Computer System Networking and Telecommunications · 2018
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.
