A method for expanding a cluster system is provided. The cluster system includes at least one Cluster Central Chassis (CCC), and a newly-added Cluster Line-card Chassis (CLC) connected with the CCC to form the cluster system. The method includes the following steps. A control plane is established. An equipment management right is switched to the CCC, so that the CCC manages the newly-added CLC. Meanwhile, a cluster line-card device, a cluster central exchange device, and a cluster system are further provided. In implementation, smooth expansion can be achieved without interrupting running equipment services in the CLC current network and without interrupting data services. Moreover, during the expansion process, hardware equipment needs not to be replaced, thus investment of users on the equipment is reduced.

A switching chassis includes more than one cascade unit and more than one switching unit, where: the cascade units have cascade interfaces to connect line processing chassis; the switching units have switching ports to connect the cascade interfaces; and any cascade interface of any cascade unit is connected to one switching port of any switching unit. A router cluster with the above switching chassis includes switching chassis and line processing chassis interconnected via optical fibers, where: any optical interface of any line processing chassis is connected to one cascade interface of any cascade unit; and any cascade interface of any cascade unit is connected to one switching port of any switching unit. With the present invention, the capacity of a router cluster can be expanded without the need to replace any component of the router cluster so that the expansion cost is lower.
