Packet Loss Recovery and Control for VoIP
Dipak K. C., Babu Ram Dawadi
Voice over Internet Protocol (VoIP) is a technology to transfer voice signal over the internet (Network). The transmission of audio data over digital packet switched networks faces lots of issues and challenges basically due to the presence of network impairments such as packet loss, delay, echo, network security and throughput. The biggest issue in the digital voice and video communication is the loss of packets due to network congestion, delay, jitter and other network factors. Different protocols have been standardized to detect and recover the lost packets to overcome the issues and maintain the quality of communication. However, for a real time application it is too late before a lost intermediate packet is retransmitted. This paper evaluates the implementation of agood Packet Loss Concealment (PLC) techniques that must be in action to minimize the effect of packet loss during voice communication. PLC algorithm is an end-to-end bidirectional transmission control scheme that minimizes the effect of data loss to improve sound quality in voice communication.
