Evaluation of an Efficient Approach to Provide Qos to Voip

Voice over Internet Protocol (VoIP) offers a wide range of benefits to both enterprises and communications & network service providers. It provides an alternate way to make a telephone call as compared to the Public Switched Telephone Network (PSTN). The industry is slowly recognizing the potential of Voice over IP and many VOIP applications have been developed in the last ten years. This work aims at examining number of problems that causes major obstacles to VoIP. This paper proposes and presents a new model of packet building namely multiple frames into a single packet (MFSP). We first, have studied the way the VoIP packets are organized, then illustrated advantages and limitations of existing voice packet’s structures. Lastly, we have proposed a new model of packet building namely multiple frames into a single packet (MFSP). The new model mitigates the existing VoIP obstacles such as minimizing the VoIP traffic through out the network and drop of VoIP packets as well as packet headers. The proposed protocol will be focused specially on the variation of the delay (well known as jitter), which is vital for VoIP QoS (quality of service). Simulation was done using NS-2 simulator. Simulation results show the ability of MFSP to eliminate the packet dropping in VoIP.
