12. © China Mobile Communications Corporation www.chinamobile.com  2-level structure including nation-wide backbone network and provincial network.  Provincial networks are interconnected through the nation-wide backbone.  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. Structure of CMNet

13. © China Mobile Communications Corporation www.chinamobile.com Structure of CMNet  Backbone nodes are connected through core nodes.When necessary, the connection between two backbone nodes are permitted.  Two types of provincial nodes: aggregation node and common node.  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.
