A number of different technologies were previously deployed with essentially identical goals, such as frame relay and ATM. MPLS has evolved with the strengths and weaknesses of ATM in mind. It has agreed that ATM should be replaced with a protocol that requires fewer overheads, while providing connection-oriented services.
MPLS is currently replacing some of these technologies in the marketplace. It seems that MPLS will completely replace these technologies in the future, thus aligning these technologies with current and future technology needs.
At the same time, MPLS attempts to preserve the traffic engineering and out-of-band control that made frame relay and ATM attractive for deploying large-scale networks. Telrad's TAG-1120 product is a high-capacity-density MPLS-based Carrier Ethernet transport switch that provides high service availability and scalability and by its cost-effectively enabling any mixture of Ethernet and TDM traffic. TAG-1120 secures the investment and provides the service provider with an agile platform enabling the deployment of any application like Wireless Backhaul, Business Delivery, DSLAM
Backhaul, SDH Replacement or Smart Grid. MPLS Network can be built by using TAG1120 only or together with 3rd party MPLS Routers (many commonly used routers are already tested to be working with TAG1120).
TAG-1120 supports any service from point-to-point (VPWS) to multipoint-to-multipoint (VPLS) over any topology:

- VPLS: Virtual Private LAN Service is used for MPLS-based E-LAN and E-Tree services as defined by the MEF. E-LAN is defined for multipoint-to-multipoint connectivity and E-Tree for point-to-multipoint with hub and spoke connectivity where traffic is blocked between spokes.
- VVPWS: Virtual Private Wire Services is used for MPLS-based E-Line (point-to-point) service as defined by the MEF
