For example, in a 3 3
IM, suppose that one cell is enqueued into the first VOMQ,
two cells are enqueued into the second VOMQ and no cell
has arrived at the third VOMQ. Then this IM will send a message
“101,100” to the scheduler. The first “1” indicates that
one cell has arrived at the firstVOMQfollowed by the separator
“0”.
