PROBLEM TO BE SOLVED: To provide a method of processing frames received at a sending port of a switching device for communication to a destination port. SOLUTION: The method includes the steps of: storing an offset value, a comparator value and an expectant value; comparing information on a frame position with the comparator value; and processing the frame. The frame processing step may include the step of communicating the frame or setting the priority of the frame. The offset and the comparator values may be part of a filter that also includes an anchor value from which the offset value is measured and a mask value that masks the frame information. The method may include the steps of combining filter results and processing the frame. The filter result combining step may include logically combining their results. Further, the method may also include the steps of merging the results and processing the frame. COPYRIGHT: (C)2010,JPO&INPIT |
