| Abstract | The premise of multiprotocol label switching (MPLS) is to speed up packet forwarding and provide for traffic engineering in Internet protocol (IP) networks. To accomplish this, the connectionless operation of IP networks becomes more like a connection-oriented network where the path between the source and the destination is precalculated based on user specifics. To speed up the forwarding scheme, an MPLS device uses labels rather than address matching to determine the next hop for a received packet. To provide traffic engineering, tables are used that represent the levels of quality of service (QoS) that the network can support. The tables and the labels are used together to establish an end-to-end path called a label switched path (LSP). Traditional IP routing protocols (e.g., open shortest path first [OSPF] and intermediate system to intermediate system [IS–IS]) and extensions to existing signaling protocols (e.g., resource reservation protocol [RSVP] and constraint-based routing–label distribution protocol [CR–LDP]) comprise the suite of MPLS protocols. |
