Load-balancing will now occur over the two serial links, but
the mechanisms will be different, depending on whether the routers
are process-switching or fast-switching. For process-switching, the
load-balancing occurs with each packet using a round-robin method.
Also, the packet counts on each link will be the same. For
fast-switching, load-balancing occurs with each multicast flow
because an (S,G) flow will be assigned to one of the physical
interfaces. |
