An ex ante forecast on economically engineered bit rates for IPTV service via xDSL transports of internodal access

摘要

Concerning broadband IPTV service (of 12/24 MHz bandwidth) on a digital subscriber line (xDSL), an algorithm (plus a numerical spreadsheet) that computes the required, economically engineered bit rates (EEBRs) of associated (aggregated) traffic is developed. The EEBR is decided by user (residential/business) behavior at a wire center and is essential for economic design/implementation/ expansion of xDSL infrastructure. Using an available set of (ex post) data on xDSL growth of services (collected over a period of semiannual terms) at a wire center, an ex ante forecast on EEBR is elucidated. An EEBR-based economic utilization of resources and connection admission control is indicated.
