Abstract
A method and a fiber channel switch element for processing receive-modify-send ('RMS') frames in a fiber channel network are provided. The method includes, determining if a received frame is a RMS frame; modifying the RMS frame without copying the RMS frame to a transmit buffer; and transmitting the modified frame. The RMS frame is modified in a receive buffer before being sent to the transmit buffer and a port state machine controls the receive buffer where RMS frames are modified. The switch element includes a port having a state machine that determines if a received frame needs to be modified before being transmitted, and if the frame is to be modified then such modification occurs in a receive buffer without being copied to a transmit buffer before such modification. A buffer select logic selects the appropriate buffer for modifying and transmitting frames from.
