Dear all,

As we are going to have RELOCATE command in sixtop draft, then we will need
add a specific format for RELOCATE. Though the format is not discussed yet,
but I think finally it will ends up something with two list of cell in the
packet and having (a) fields to indicate where the cell list to be added
and list to be removed are. Of course , with RELOCATE command byte in the
frame. I think this format can be a general format for ADD , DELETE  and
RELOCATE.

With such format,

   - if there is only list of cell to be added, then the frame can be
   represented as ADD command
   - if there is only list of cell to be removed, then DELETE  command
   - if there are both two list of cell, and they have the same number,
   then RELOCATE command..

The benefit of using this two cell list format is that:

If the node wants to relocate one cell and at the same time add some cells
OR delete some cells, with single sixtop transaction, which is

   - there are two list of cell, one for adding, one for deleting, but
   length of adding list is longer than deleting list (Add command+Relocation
   command)
   - there are two list of cell, one for adding, one for deleting, but
   length of adding list is shorter than deleting list (Delete
   command+Relocation command)

Let me know your thought.
