摘 要:现代生活中,几乎每个人离不开网络,其中,有线网络一直扮演着至关重要的角色。总结一下周围的有线通信访问网络,可以划分为接入层、汇聚层、核心层。处于每一层上的每一个网络节点(例如汇聚节点)又组成了整个不同层次的环网(例如汇聚环),虽然基站分布(指基站机房设备,例如PTN设备)较为杂乱,但其都在各自的网络下,各司其职。而光纤通信的发展也使得基站与基站之间、基站与用户之间建立起了千丝万缕的联系。

Abstract:In modern life,almost everyone can’t do without the network. Among them,the wired network has always played a vital role. To sum up,the wired communication access network around us can be divided into the access layer,the aggregation layer,and the core layer. Each network node (such as a sink node) on each layer constitutes a ring network of different levels (such as an aggregation ring). Although we see that the base station distribution (referring to the base station equipment room,such as a PTN device) is messy,they are all under their respective ring networks and perform their duties. Due to the development of optical fiber communication,the base station and the base station are full of inextricable links between the base station and the user.
