The problem of estimating rate plan settings on multiservice access networks is stated. Given the triple-play nature of broadband services we formulate the interconnection between the standard service set and available access port settings - output packet buffer capacity and bandwith. We discuss usual Internet Service Provider access network from the last uplink to the end-user customer equipment access port. As an industry standard we choose IP-Television, internet data transfer and streaming video as primary services. Baseline protocols of these services are stated along with respective quality of service requirements. IP-TV service is modeled according to DVB-IPTV standard with H.264 encoding using MPEG-TS multiplexing streams over RTP and UDP protocols with IP-multicast distribution. Using experimental data we show high burstiness of H.264 traffic patterns and take care of it cduring calculation of required bandwith parameters. Data transfer service represented by popular TCP-based internet applications. We are giving attention to TCP flow control algorithms and to Application level flow control. From experimental data and industry adopted baselines of internet applications we estimate quality of service parameters as a function of customer connection settings. Unlike usual ISP approximations of core links capacity, out method allows to estimate access port settings as a function of rate plan for required service set and quality of service.
