Structure of CMNet 42 -level structure including nation-wide backbone network and provincial network. 4 Provincial networks are interconnected through the nation-wide backbone. 4 Two types of nation-wide backbone nodes: backbone node and core node. In principle, core nodes are connected fully-meshed, in order to save links, they are partly connected fully-meshed recently. © China Mobile Communications Corporation www. chinamobile. com
Structure of CMNet 4 Backbone nodes are connected through core nodes. When necessary, the connection between two backbone nodes are permitted. 4 Two types of provincial nodes: aggregation node and common node. 4 Aggregation nodes are used to connect common nodes to the nation-wide backbone. In principle, Aggregation nodes are connected fully-meshed, in order to save links, we use partly full-mesh connections recently. © China Mobile Communications Corporation www. chinamobile. com
