IP / MPLS Technologies



  • MPLS stands for “Multiprotocol Label Switching”. In an MPLS network, incoming packets are assigned a “label” by a “label edge router (LER)”.
  • Packets are forwarded along a “label switch path (LSP)” where each “label switch router (LSR)” makes forwarding decisions based solely on the contents of the label.
  • Label Switch Paths (LSPs) are established by network operators for a variety of purposes, such as to guarantee a certain level of performance, to route around network congestion, or to create IP tunnels for network-based virtual private networks.
  • MPLS network is widely deployed & used by all the service providers.
