CSMA/CD-based Ethernet over passive optical network for delivery of voice-over-IP traffic

摘要

This work investigates the applicability of a carrier-sense multiple access with collision detection (CSMA/CD)-based EPON to transport real-time voice-over-IP (VoIP) traffic to home and office users. Results show that a realistic Ethernet passive optical network (EPON) with 32 optical network units (ONU's) clustered within 100 m to 1 km of the SC can deliver VoIP packets with low delay and manageable jitter which comply to current standards for QoS requirements, and thus allowing cost-savings through integration with commercially available and installed devices.
