Impact of Background Traffic on VoIP QoS Parameters in GPON Upstream Link

摘要

The transmission of multimedia services over IP networks has highly increased in recent years. Multimedia services can be imagined as e.g. VoIP (Voice over IP), video telephony or video streaming. It is expected that amount of transferred data will also grow in upstream, because a lot of multimedia services is interactive. Generally, most of the services are sensitive to bandwidth which can be utilized itself. Decreased given bandwidth means degradation of QoS (Quality of Service). Many research teams have investigated an impact of various effects on QoS parameters of multimedia services [1-14].
