Comparison of MPLS- and IP-based Transport in Future RANs Under Varying QoS Requirements

چکیده
The paper provides a proposal for an MPLS-based transport network for future Radio Access Networks (RANs) and compares this with a regular IP-based transport network. Our MPLS-based approach takes into account the specific needs of current and future RANs especially with respect to QoS requirements and flexibility. In the paper we compare the MPLS-based solution with a regular IP-based network. Our simulation studies based on an extension of the network simulator 2 show that MPLS is able to fulfill the requirements of future RANs and vastly outperforms a regular IP-based solution. MPLS is able to deliver very stable figures for delay, jitter and packet loss even if the traffic mix within the network changes, which is not the case for an IP-based radio access network.

Currently we see a discussion on the transition from ATM-based transport to IP transport in the UMTS Terrestrial Radio Access Network (UTRAN). Issues that result from the transition to IP are QoS, esp. delay, jitter, loss, bandwidth guaranties and in sequence delivery of packets for voice traffic. The paper compares two solutions for future UTRANs, native IP multi-path transport and MPLS (Multi...
