ATM transport over multi-protocol label switching

摘要

User traffic of one type must traverse many diverse networks, each operating by different paradigms and requiring different protocol stacks, before it reaches the destination. MPLS (Multiprotocol Label Switching) is being developed to solve some of the problems which involve the existence of different protocols along the traffic path. There is currently no accepted way of transporting ATM cells over an MPLS domain. New ways of packetizing ATM cells into labeled MPLS packets for transporting over an MPLS domain are described.
