Description
A promising next-generation version of service that could be availed from local exchange carriers (LECs) refers to streaming Internet protocol based television (IPTV) programs into subscriber premises via traditional copper pairs. The present study addresses provisioning economically-budgeted and optimally-engineered bit rates (EBRs) in implementing IPTV technology in the local-loop via copper-pairs using the so-called (ADSL2/ADSL2+) technology (with high-speed/large bandwidth considerations plus copper-bonding for bandwidth sharing capabilities). Also studied is the way to extend the backhaul transport of IPTV on copper-lines (plus any other local-loop transmissions that may co-exist) onto an "all-optical" trunk of the inter-office facilities (IOFs) in the edge/core network cloud of the telcos. A model of a core network topology is analyzed for traffic considerations so as to decide on blocking probability at a specified egress node under different conditions of burstiness. The problems posed are analyzed via computations/simulations on Matlab(TM) (v6.5). Inferential remarks are gathered, conclusions are drawn and open-questions yet to be researched are indicated.
