QoS in VoIP Networks Project Synopsis

Project Title: QoS in VoIP networks

Project Description:

Voice over IP (VoIP) technology is rapidly emerging in the telecommunication market. It enables a telecommunication company to employ a single network to transmit both data and voice traffic. The VoIP technology is gaining popularity in the enterprise and residential markets because the quality of the voice packets transmitted over the IP network is comparable to the quality of analog signals sent over the Public Switched Telephone Network (PSTN).

Aims and objectives:

To review, study, model and analyse some of the following:
• VoIP applications and architectures (Consumer, Enterprise, Service Provider)
• VoIP devices (telephones, gateways, servers)
• VoIP signalling protocols and codecs (H.323, SIP, MGCP, G711)
• Transport layer protocols (UDP,IP,RTP)
• VoIP performance metrics (Delay, Jitter, MOS)
• QoS mechanism for VoIP (Queueing, IntServ, DiffServ, MPLS-TE)
• Types of queuing systems (FIFO, Priority, ToS, WFQ)
• VoIP vendors and current trends

Product Details:

The primary aim of the project is use OPNET’s ITGURU modelling software to model and analyse the performance of a mixed traffic network with particular emphasis on the roll out of VoIP applications.

Resources Required:

OPNET ITGURU modelling software
