This paper analyzes MPLS signaling protocols for traffic engineering, shows the capability of providing traffic engineering in MPLS compared to the conventional routing protocol, and explains the MPLS LSR operations based on the basic LSR functionality of classification, queue, and scheduling. CR-LDP, RSVP and RSVP-TE are summarized and analyzed based on how to set up LSP for TE with help of protocol messages. In addition, the comparisons of CR-LDP, RSVP, and RSVP-TE are conducted based on the aspects of LSP reliability and LSP adaptability. A performance metric such as throughput is adopted in order to measure the capability of MPLS traffic engineering based on computer-based simulation.
