TLDR
This paper introduces IMS (IP Multimedia Subsystem) and then looks at implementation agreements, methods and protocols for transport of voice over MPLS (multi protocol label switching) networks.Abstract:
In this paper, we discuss currently evolving technologies for packet based real-time voice communication Packet based voice has gained popularity in the toll-quality market due to its flexibility and cost effectiveness IMS (IP Multimedia Subsystem) is being developed for converged voice and data services While initially it was intended for mobile networks, it has been expanded to include support for fixed networks In the wired network, the quality of service needed for media traffic can be provided by MPLS and related protocols The traffic engineering and quality of service mechanisms of MPLS and Diffserv allow the differential treatment of premium traffic on predefined LSPs (Label Switched Path) Recently T-MPLS has been introduced as the transport network for connection oriented packet switched traffic, dropping some of the MPLS features that were irrelevant for connection oriented applications We introduce IMS and then look at implementation agreements, methods and protocols for transport of voice over MPLS (multi protocol label switching) networksread more

OPNET simulation of voice over MPLS: With Considering Traffic Engineering
TL;DR: By using voice packet end-to-end delay performance metric an approach is made to estimate the minimum number of VoIP calls that can be maintained, in MPLS and conventional IP networks with acceptable quality.

A comparative study of in-band and out-of-band VOIP protocols in layer 3 and layer 2.5 environments.
TL;DR: Evaluating different VoIP signalling protocols in terms of their key performance metrics and the impact of security and packet transport mechanisms shows that in-band signalling protocols are highly optimised for VoIP telephony and outperform out-of-band signaling protocols in certain key areas.

Performance analysis of video on demand and video streaming on the network mpls traffic engineering
TL;DR: This paper evaluated the performance measures such as transfer time, delay, throughput using OSPF as routing protocol and tunneling to determine the inside path the process of different types of traffic in their movement in a network MPLS-TE.
Performance Analysis of MPLS over VOIP
TL;DR: The simulation study is carried out to clarify the advantages of employing MPLS-TE for multimedia applications and measured the performance matrices i.e. delay, delay variation, throughput, page response time and packet loss for various kinds of traffic in their motion in a congested network.
