VOICE COMMUNICATION THROUGH ETHERNET:--- STUDY OF VOICE PACKETIZATION STRATEGIES

摘要

Voice communication requires the real time transmission performance. The delay of packetization takes a main part of the end-to-end delay for voice transmission in packet switching systems. When Ethernet is used for voice/data integration, to find a suitable choice of packetization methods for voice traffic, we have compared the delays of packetization under two strategies: one with variable packet length like in Ethernet for data; the other with fixed packet length. After having given a general analysis, some numerical results are presented with different voice coding and speech activity detection techniques.
