Drag and drop the MPLS concepts from the left onto the descriptions on the right.


正解:

Explanation:
+ allows an LSR to remove the label before forwarding the packet: penultimate hop popping
+ accepts unlabeled packets and imposes labels: label edge router
+ group of packets that are forwarded in the same manner: forwarding equivalence class
+ receives labeled packets and swaps labels: label switch router
Explanation:
A label edge router (LER, also known as edge LSR) is a router that operates at the edge of an MPLS network and acts as the entry and exit points for the network. LERspush an MPLS label onto an incoming packet and pop it off an outgoing packet.
A forwarding equivalence class (FEC) is a term
