Structure of CMNet2-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. China Mobile Communications Corporation www.chinamobile.com

Structure of CMNetBackbone 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. China Mobile Communications Corporation www.chinamobile.com

Structure of CMNetAggregation nodes are connected to the nation-wide backbone nodes directly. In principle, common nodes are connected to the nation-wide backbone through aggregation nodes. When necessary, the direct connection between common nodes and backbone/core nodes are permitted.
