Quality of Service Test by Codec Performance
Shunge Li, Bharat Bhargava, Dawei Wang · Purdue e-Pubs (Purdue University System) · 1996
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 .lPEGcompressor and decompressor and discuss various policies under which QOS negotiation process can follow if a QOS test fails.
