  2. Attach an input stream to the BPipe object.
  3. Attach one or more output streams to the BPipe object.
  4. Add to or change the data in the header.
  5. Select the fields in the data packets that you want transferred to the output streams. Create new data packet fields.
  6. Map the core and output data packet images.
  7. Process the data packets.
  8. Close the BPipe.
