Jointly launched four-month China MAN Trial' 2000. Taking IP technology as the theme, the trial involves metro optical transmission network, backbone routing switching broadband integrated access, IP value added services, broadband multimedia applications, network operation& maintenance, billing and other aspects.

This clustering strategy makes all the sub-cluster with the same size and distributed evenly, avoiding the potential failure caused by backbone routing.

该分簇方案形成的簇大小一致、位置分布均匀，避免了由移动节点担任骨干路由可能带来的失效。
