Performance Evaluation of MPLS TE Signal Protocols with Different Audio Codecs for Voice Application
Sarmad Khaleel Ibrahim, Mahmoud M. Al-Quzwini · 2012
This paper studies the performance of MPLS networks with TE signal protocols in relation with voice codecs. Simulation were performed and compared for a multisite network with PCM and GSM based VoIP. Simulation results show that the MPLS network with CR-LDP TE signal protocol outperforms the MPLS network with RSVP TE signal protocol in terms of both the total amount of received voice packets and the number of maintained calls for both voice codecs.
