摘要： 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.

摘要： A method and system of data communication, switching network board are disclosed. The data communication system includes multiple line card chassis, each including multiple line cards, at least one switching chip and at least one relay chip. The line card is respectively connected to the switching chip and the relay chip of the same line card chassis. The switching chip of one line card chassis is connected to the relay chip of at least one of other line card chassis. The relay chip of the one line card chassis is connected to the switching chip of the at least one of other line card chassis. The switching network board includes a switching chip and a relay chip. By implementing the above embodiments, the networking complexity is reduced, the networking cost is saved and the system reliability is enhanced in the case that a few line card chassis are cascaded.
