正好我也在查这个概念 把我查到的给你说下吧

业务节点（service node）指的就是提供业务的实体。个人认为像ATM交换机，IP路由器都是业务节点。以下是我查到的其他的相关说法，你看下，应该不会错。

webopedia上说业务节点就是edge switch，而维基上对edge switch的定义如下（PS：edge switch肯定是edge device的一种了）

Edge devices are routers, routing switches, integrated access devices (IADs), multiplexers, and a variety of metropolitan area network (MAN) and wide area network (WAN) access devices that provide entry points into enterprise or service provider core networks. Edge devices also provide connections into carrier and service provider networks.

业务节点就是业务实体网元。交换节点就是负责交叉和汇接的设备
