Improve QoS (Quality of Service) by destructing Security Issues

VoIP services are scarifying, due to delay in transmission of voice packets (Latency), echo, jitter, packet loss and other Quality of Service (QoS) problems arrived in VoIP phones. The weakness on QoS is managing by voice and data service together on a VoIP network. In this paper we dedicated to studying the response of data transmission quality, characteristic of voice quality, the service quality and diagnoses the problem arrived on VoIP protocol suite. For this reason, we suggest, to manage the weakness of VoIP related protocol by design of measurement management process model also use to analyzed quality item driven per voice service that can increase the quality and come up the result of MOS, delay, jitter, packet loss value, voice processing, filtering, try to achieve Qos requirements, removing the m iscellaneous QoS security issues, Improving QoS, and obtained the idea about Software Queueing Mechanisms etc.
