switching chip on an LPU is fully connected with all of the level-2 switching chips on
SFUs. As a result, the same number of cells can be distributed to each level-2 switching
plane. This implements load balancing across switching planes and facilitates fault
tolerance.
After the cells reach the crossbar switching chips, the crossbar switching chips schedule
the cells to the corresponding outbound interfaces according to the destination interfaces
of the data packets. The cells are then sent to the level-3 switching chips on another LPU.
At this point, the switching of the cells by the level-2 switching chips is completed.
After the cells reach the level-3 switching chips on another LPU, the system searches for
the destination interfaces. Once found, the cells are reassembled and sent out through
physical interfaces. At this point, the switching of the data packets is completed.
