Abstract:
3GPP Long Term Evolution (LTE) and Evolved Packet Core (EPC) are the most advanced technologies in the wireless and mobility field, since they provide high speed data and various sophisticated applications to Mobile Users. LTE is a key technology to various high speed applications, which require efficient performance. Packet Jitter is one of the most important performance parameters for those applications. Thus, several researches have been conducted in the LTE radio layer to study the Jitter performance, but they lack the EPC core network layer effect. This paper presents intensive simulation study of LTE-EPC traffic Jitter performance over Multiprotocol Label Switching (MPLS) core network using a Poisson Process traffic generator. MPLS is proposed in conjunction with the EPC to provide better efficiency in modern integrated networks in terms of packet Jitter variations, which is shown to be much better than IP routing trends. The simulation investigates both of the IP and MPLS models, and evaluates the end-to-end performance. The MPLS Model is simulated by MPLS core routers attached to the Packet Data Gateway (P-GW) EPC data plane, while the IP model uses IP core routers instead. These two models are fed by a Poisson traffic source, which matches the statistical properties of real-time IP internet traffic. The Jitter performance of the two LTE-EPC models shows the enhancement caused by MPLS.
