Abstract—IMS is an evolving definition of an architecture
that solves the continuing demands and frustrations of users and
enterprises. IMS is a whole new way to deliver multimedia
services (voice, video, data, etc.) regardless of the device (mobile
phone, landline phone, cable, Internet, etc.) and will change the
way all of us relate to our increasingly digital world. Real-time
applications such as voice and video have a great deal of demand
over IMS network. The QoS is the major concern for real-time
application such as voice and video. In order to fulfill the users
demand, it is necessary to improve the QoS.
In this work, we implement IntServ and DiffServ with MPLS which can have great potential in improving the QoS scheme in IMS for video conferencing. We evaluate the performance of QoS for video conferencing over that mechanism perform with IMS. The performance is evaluated based on some QoS parameters such as end-to-end delay, packet loss and jitter. In order to investigate the performance of QoS scheme in IMS, we analyze the simulation results. The investigation shows that proper adaptation of QoS provides qualitative transmission of video conferencing in wireline.
Finally on the basis of the simulation results, we study the QoS performance and propose difference schemes to enhance the QoS performance in IMS based on the QoS parameters.
Index Terms—IP multimedia subsystem (IMS), multi-protocol label switching (MPLS), video conferencing (VC), quality of service (QoS).
