Quality of Service Test by Codec Performance
نویسندگان
چکیده
Quality of Service (QOS) test is a process of verifying the system's acceptability of a given QOS specification. Although the result of a QOS test depends on such system performance factors as the available reSOllfces, it is also influenced by the implementation of a codec scheme involved. In this paper, we argue that a good knowledge about the performance of the compressor and decornpressor can provide solutions to QOS test. We present OUf approach to QOS test based on the performance of a .lPEG compressor and decompressor and discuss various policies under which QOS negotiation process can follow if a QOS test fails.

Modeling the Effects of Burst Packet Loss and Recency on Subjective Voice Quality
A. INTRODUCTION Voice over IP networks differ from conventional telephone networks in that voice quality is affected by a wider variety of network impairments and can vary from call to call and even during a call. It is therefore desirable to monitor call quality in order that service providers can properly provision networks and that network resources are properly allocated. Passive monitoring...

متن کاملEvaluation of ITU-T G.728 as a Voice over IP codec for Chinese Speech
Voice-over-IP is expected to become a popular service offered by the internet. Thus, it is important to ensure high quality of service. In this paper, we look at two standards proposed for evaluating the intelligibility of Chinese speech. Adopting the philosophy and methodology of the Diagnostic Rhyme Test (DRT) for testing English speech, the Chinese Diagnostic Rhyme Test (CDRT) evaluates the ...
