Distributed Multi-Link Trunking (DMLT) or Distributed MLT is a computer networking protocol designed by Nortel used to load balance the network traffic across connections and also across multiple switches or modules in a chassis. The protocol is an enhancement to the Multi-Link Trunking (MLT) protocol.

| DMLT between 2 stacked 5530 switches to a ERS 8600 switch |
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.
