Abstract(in English) Broadband access services such as Asymmetric Digital Subscriber Line (ADSL) and Fiber To The Home (FTTH) have become popular now in the Internet. In Internet service provider (ISP) networks, gains of statistically multiplexing traffic from broadband access users are likely to be much lower than that for narrow-band access users. Accommodation design methods considering users' access link speed are needed for ISP networks. ISP's edge routers are bottleneck, because they multiplex traffic from many users. In this paper, we model the traffic only using mean rate, burst length and access link rate, because input traffic from users to the router is unpredictable. And we evaluate buffer overflow probability of packet in the router queue by using discrete time analysis. Finally we evaluate broadband access impacts on user accommodation design.
