WTFC BASED INTEGRATION OF VOICE AND DATA TRAFFIC

Integration of voice and data traffic in packet switching networks is facing problems of admission control, resource reservation, scheduling, flow control and flow conformance control. WTFC (Window-Time Flow Control) technology offers a method for efficient end to end packet rate and window regulation, keeping the network at the working point of on average empty packet queues. This property makes WTFC a promising technology in the area of voice and data integration, solving several common problems: data flow regulation, voice coding and rate selection, and outbound queue scheduling. In this paper, the approach to the WTFC usage in voice-data integration is proposed. Experimental realization is tested in simulation environment. Conclusions are developed.
