A New Internet-Draft is available from the on-line Internet-Drafts directories. This draft is a work item of the Transparent Interconnection of Lots of Links Working Group of the IETF. Title : TRILL: Data Label based Tree Selection for Multi-destination Data Authors : Yizhou Li Donald Eastlake Weiguo Hao Hao Chen Naveen Nimmu Somnath Chatterjee Sunny Rajagopalan Filename : draft-ietf-trill-tree-selection-01.txt Pages : 19 Date : 2015-07-05 Abstract: 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 trees; however, there is a limited capacity for such pruning information. This document specifies an optional facility to restrict the TRILL Data packets sent on particular distribution trees by VLAN, FGL, and/or multicast group thus reducing the total amount of pruning information so that it can more easily be accommodated by fast path hardware.
