Research of campus high-speed net model

With campus networks business growing, the networks are asked to meet real-time and half real-time business performance and the quality of services such as VOIP and IPTV. Through the measurement and analysis of campus network´s primary service, association deduce the self-similarity model and queuing model, and the correlation value ρ is calculated. This paper sets up a suitable multi-port input queuing model, and calculates the network bandwidth of this model which satisfies the need of real-time and half real-time.
