Abstract：MAN carries many services such as home broadband，internet TV，internet private line，voice and so on. With the rapid development of video service，MAN is facing many problems such as insufficient equipment capacity，insufficient upload bandwidth and so on. The analysis and research of MAN traffic model and the planning of network capacity in advance are very important for the later business development of operators，and are also the focus of current research. In this paper，the current network services and traffic situation of a city are analyzed and analyzed. Combining with the business development trend，the traffic models of home broadband and interconnected television in the next two years are predicted to guide the construction of MAN.
Keywords：MAN；home broadband；internet TV；traffic model
