In this paper, the authors study the performance of Multi-Protocol Label Switching (MPLS) networks for VoIP applications when applying both Traffic Engineering (TE) signal protocols and Quality of Service (QoS) algorithms. The used QoS algorithms are First-In First-Out (FIFO), Priority Queuing (PQ), and Weighted Fair Queuing (WFQ). The study addresses different audio codec's including PCM (64Kbps), GSM FR (13Kbps), G.723.1 (5.3Kbps), G.726 (16Kbps), G.728 (16Kbps), G.729 (8Kbps) and IS-641 (7.4Kbps). In term of number of maintained calls, the results show that applying QoS algorithms improves the performance of the MPLS network with RSVP TE signal protocol more than that with CR-LDP TE signal protocol.
