On a multilink bundle, packet fragments from all queues except Q2 are transmitted to Q0 on constituent links. On the Q0s of constituent links, the packets are queued in a weighted round-robin fashion to enable per-fragment load balancing.
Figure 33 shows how queuing is performed on the constituent links.
Figure 33: Queuing on Q0 of Constituent Links
Packet fragments from the multilink bundle are queued to constituent links one by one in a weighted round-robin fashion. Packet 1 from Q0 on the multilink bundle is queued to Q0 on Constituent Link 1, packet 2 from Q1 on the multilink bundle is queued to Q0 on Constituent Link 2, packet 3 from Q3 on the multilink bundle is queued to Q0 on Constituent Link 1,and so on.
