  • System for multi-chassis interconnection and method for chassis connection
    Patent number: 8619764
    Abstract: A system for multi-chassis interconnection and a method for chassis connection are disclosed. The system includes at least three chassis; each chassis includes a first switch fabric unit (SFU) and a second SFU; the first SFU in the first chassis is connected to the first SFU in other chassis; and the second SFU in the second chassis is connected to the second SFU in other chassis. In the embodiments of the present invention, different SFUs in the chassis of the multi-chassis interconnection system are connected to different main chassis, thus overcoming the technical defect in the prior art that other chassis in the multi-chassis interconnection system are unable to exchange data when the main chassis is faulty. Therefore, in the embodiments of the present invention, other chassis in the multi-chassis interconnection system can still exchange data normally when the main chassis is faulty.
