Abstract

A multi-stage switch fabric (SF) is provided. The multi-stage SF includes a line card chassis (LCC) and a fabric card chassis (FCC). The FCC includes a stage-1 switch element (S1), a stage-2 switch element (S2), and a stage-3 switch element (S3), where the S3 corresponds to the S1, and the S2 is coupled to the S1 and S3 respectively. The LCC includes an interface component and a line card (LC) coupled to the interface component, where the interface component is coupled to the S1 and S3 in the FCC respectively. Through the technical solution under the present invention, when a switch element generates flow control information and requires another switch element or an LC to respond to the flow control information, a timely response can be received.
