Support as a co-author. This draft provides a solution of data label based loadbalancing for BUM traffic, it can effectively compact multicast forwarding table space for each RB, the space in chipsets is normally very precious.



Thanks,

weiguo

Abstract for: TRILL: Data Label based Tree Selection for Multi-destination Data

   TRILL uses distribution trees to deliver multi-destination frames.
   Multiple trees can be used by an ingress RBridge for flows regardless
   of the VLAN, Fine Grained Label (FGL), and/or multicast group of the
   flow. Different ingress RBridges may choose different distribution
   trees for TRILL Data packets in the same VLAN, FGL, and/or multicast
   group. To avoid unnecessary link utilization, distribution trees
   should be pruned based on VLAN and/or FGL and/or multicast
   destination address. If any VLAN, FGL, or multicast group can be sent
   on any tree, for typical fast path hardware, the amount of pruning
   information is multiplied by the number of tree; however, there is a
   limited capacity for such pruning information.
