(1) When written as AToM, it is short for Any Transport over MPLS, a technology developed
by Cisco for transporting Layer 2 packets over an
IP/MPLSbackbone. The
technology is designed to let
ISPs combine multiple disparate data networks -- such as
Ethernet,
ATM, Frame Relay,
and Serial/PPP networks
-- onto a single MPLS-based backbone to save operational costs. AToM is
sometimes called Layer 2 MPLS.
