what is diffrence betwwen mpls and frame really
The Multiprotocol Label Switching (MPLS) protocol is a
relatively new technology (less than 10 years old), and many
organizations have been actively replacing their frame relay
networks with MPLS service when their contracts expire.
"MPLS is a mechanism for labelling traffic flows to define a
path through a complex network
When using frame relay, you configure Layer 2 on your
router, ending up with a WAN network with a connection to a
central cloud. Through that cloud, you have connections
(permanent virtual circuits or PVCs) to whichever remote
sites you've requested and are paying for. If you have a
fully meshed network (where every site has a connection to
every other site), you pay for every one of those PVCs,
which can become quite expensive.
