运营商中比较重要的网络有传输网,传输网的建设规模以及网络的质量对全业务的发展可以说是有着很重大的意义。随着网络不断朝着扁平化的方向进步,以往的传输网发生了改变,而这种改变主要是体现在承载层的渗透。所以市场上对于传送网又提高了需求。例如通过OTN技术使得宽带的容量得到扩充,使传输的速度也可以得到提高。本文主要是针对OTN和SDH传输网的相关技术进行论述。
Operators in the more important network transmission network, transmission network construction scale and the quality of the network for the development of the whole business can be said to be of great significance. As the network continues to move toward flattening, the transmission network has changed in the past, and this change is mainly reflected in the carrier layer infiltration. Therefore, the market has raised the demand for transport networks. For example, OTN technology enables the expansion of broadband capacity, so that the transmission speed can be improved. This article is mainly for OTN and SDH transmission network related technologies are discussed.
