(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/
MPLS
backbone. 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.
