Performance Evaluation of Audio Distribution System over Ethernet using a L 1 / L 2 Hybrid Switching

In this paper, we propose an Ethernet based audio distribution system with a new L1/L2 hybrid switching scheme and evaluate its performance. The proposed scheme not only offers guaranteed low latency and jitter characteristics that are essentially required for the distribution of high-quality uncompressed audio traffic and but also provide an efficient transmission of data traffic on the Ethernet environment. For verifying the feasibility of the proposed L1/L2 hybrid switching scheme, we use OMNeT++ as a simulation tool with various parameters. One can see that proposed scheme can provides outstanding characteristics in terms of both jitter characteristic for audio traffic and transmission efficiency of data traffics.
