Method and system for routing and filtering network data packets in fibre channel systems |
摘要 |
A fiber channel switch element with an alias cache is provided for routing and filtering frames. The alias cache includes plural entries including a control word having plural fields including an action code for routing frames; an alias word that is compared to incoming frame data using a frame byte compare block; and a bit mask generator for filtering bit combinations from the frame byte compare block; and a depth match block for determining equality between a control word depth field and incoming frame depth field. Frame data comparison is performed on a bit by bit or byte-by-byte basis. An alias cache entry also includes prerequisite data to determine if results of a different entry are to be used to determine an entry match. The action code routes a frame to a processor, discards a frame, sets a status for inspecting a frame or routes a frame based on a standard Fiber Channel addressing scheme.
