'''Distributed Multi-Link Trunking''' ('''DMLT''') or '''Distributed MLT''' is a proprietary [[computer networking]] [[Protocol (computing)|protocol]] designed by [[Nortel|Nortel Networks]], and now owned by [[Avaya]],<ref>{{cite web

DMLT allows the ports in a trunk (MLT) to span multiple units of a stack of switches or to span multiple cards in a chassis, preventing network outages when one switch in a stack fails or a card in a chassis fails.
