Hi All

Please help me to confirm these problem:
The fucntion "cn_send()" in file "abrconnection3.c"  has some problem like
this:
1. The assignment  " Number_of_Cells=
(int)(pval(cn,cn_burst_length)->u.i);"   is it right ?
2. This loop is not  exact  !?

for (j=0;j<Number_of_Cells;j++)
   {
           ev_enqueue(MY_SENDCELL,(Component *)cn,
                     (Component *)cn,
                     ev_now(),
                 abrconnection3_action,
                     (Cell *)NULL,NULL,
                    (caddr_t)NULL);
         
           cn->cn_num_sent++;
     
   }

Send  some Cells nearly at the same time! I think that the function call 
ev_enqueue(, , ,ev_now(), , , , ,)    must be 
ev_enqueue(, , ,ev_now() + "interval to send 424 bits of a cell", , , , ,) 
Thanks you very much

This is function cn_send()
static caddr_t
cn_send(cn)
   register BATCHConnectiont *cn;
   {
   VPI vpi=cn->cn_vpi;
   register Cell *cell[1000];
   tick_t interval,increment;
   int i,j,time_now;
   int Number_of_Cells,length;
   tick_t time;
   Neighbor *n;


if (USECS_TO_TICKS(pval(cn, cn_start_time)->u.i) <= ev_now() )
     {

      if (cn->cn_num_sent < (pval(cn,cn_trans_size)->u.d*1000000/424))
        {

         cn->cn_cbr_vbr=1;

        /* if the # of cells sent is less than transmission size, 
           increment the # of cells sent and send a cell to the
           bte */
  
          Number_of_Cells= (int)(pval(cn,cn_burst_length)->u.i);

          if (cn->cn_simple_connection == 0)
          {
           for (j=0;j<Number_of_Cells;j++)
             {
           ev_enqueue(MY_SENDCELL,(Component *)cn,
                     (Component *)cn,
                     ev_now(),
                 abrconnection3_action,
                     (Cell *)NULL,NULL,
                    (caddr_t)NULL);
         
           cn->cn_num_sent++;
     
              }
          }
           /* Then schedule an EV_SENDCELL for the next cycle */
          
 
           ev_enqueue(EV_DONE_ON, (Component *)cn, (Component *)cn,
                      ev_now()+2*j, abrconnection3_action, (Cell *)NULL,
                      NULL, (caddr_t)NULL);

          }
      }
      else {
 
        interval = USECS_TO_TICKS(pval(cn, cn_start_time)->u.i);
        ev_enqueue(EV_START, (Component *)cn, (Component *)cn,
         ev_now()+
                   interval, cbrconnection_action, (Cell *)NULL, NULL,
                   (caddr_t)NULL);
       } 


          return ((caddr_t)cn)
}
