A modified optical network for interactive video-on-demand services

In typical proposals for video-on-demand (VOD) networks, customers are serviced individually by allocating and dedicating a transmission channel and a set of service sources to each customer. An interactive VOD optical network is proposed that can offer video, TV, banking and shopping services (among others) to a large number of users. Several network parameters are studied using computer simulation taking into account effects like fiber dispersion, node distance and network usage. The studied parameters include maximum overall fiber transmission rate, average user waiting time, and fiber percentage usage time.
