Abstract: A method for specialized processing of data in a port-extended network comprises receiving, by the control node of the port-extended network, a data frame that includes, at a first field of the data frame, information indicative of an incoming port at which the data frame was received, the first field having been inserted by a satellite node associated with the port. The method also comprises determining that one or more packets of a frame require specialized processing, and replacing the information contained in the first field with information indicative of the specialized processing. The method further comprises replacing information contained in a second field with information indicative of an outgoing port of a second satellite node of the port-extended network. A modified data frame is transmitted onto the port-extended network, the modified data frame that includes the information indicative of the specialized processing in the first field.
