e' un post confuso che mischia dati, "si dice" e commenti il costo della banda per cliente aggiuntivo e' praticamente 0 ma questo non significa che il costo della rete sia 0 significa che una rete ha un costo che e' largamente indipendente dal numero di utenti effettivi. il prezzo di una rete per utente e' sostanzialmente una allocazione dei costi complessivi secondo un criterio arbitrario (ogni criterio di allocazione e' arbitrario). invito a leggere qui: http://bit.ly/ifq5zG sembra difficile, ma in 7 minuti ve la cavate
Where congestion does exist, it occurs at the central office — usually because the company inadequately provisioned a sufficiently large data pipe to handle the traffic. Since these circuits are increasingly fiber-based, congestion issues disappear when AT&T uses technology from this century instead of the last.
nel post di cui sopra, al punto "alcune dimensioni della rete italiana" si spiega perche' talvolta si usa la tecnologia del secolo scorso...
AT&T argues heavy users are overburdening their DSL lines, but their prescription makes no sense. The company says, despite the alleged traffic jam, it is more than willing to sell users additional capacity for $10 per 50GB increment. If AT&T’s aim was to cut congestion, they would be unwilling to sell additional capacity they don’t have to customers who need it.
questa e' ovviamente una cavolata. il prezzo e' una tecnica di allocazione delle risorse. sul tema u-verse ho commentato qui http://bit.ly/ihssVH in realta' poi qualcuno mi ha scritto dicendo che la rete che alimenta i dslam e' separata, sostanzialmente monodirezionale, spesso non in fibra ma in coax nel qual caso e' possibile che IP sia congestionato e il video di at&t invece sia fluido. non ho elementi per ritenere se sia vero o falso, non ne so abbastanza sulla loro architettura di rete, per cui tenderei a non cambiare giudizio tra qualche giorno dovremmo uscire con un bell'articoletto sulla net neutrality che tocca questi temi... ciao, s.
