This paper describes the implementation and demonstration of local networks for the hyper-media photonic information network (HM-PIN), a candidate for the information service platform offering broadcast and telecommunication services. In addition, the feasibility of the HM-PIN is also demonstrated using prototype local network systems. This local network adopts architecture based on wavelength-division-multiplexing (WDM) and broadcast-and-select (B&S) switching, and supports all HM-PIN services except inter-local-network communication. The major issues of this proposed network are the technologies that support many broadcast channels and reduce channel selection cost. This paper also considers the combination of WDM technology and three alternatives: electrical TDM, subcarrier multiplexing (SCM or electrical FDM), and optical TDM (O-TDM). Three 128 ch (8 wavelengths 16 channels) WDM B&S prototype systems are built to demonstrate the feasibility of the proposed HM-PIN. In WDM/SCM, 30 and 20 Mb/s channels are realized as 16-QAM and 64-QAM, and 155 Mb/s channels are realized by WDM/TDM. Moreover, these three prototypes were connected to form a small HM-PIN and applications such as video distribution and IP datagram cut-through are demonstrated. Furthermore, the delay and throughput of the HM-PIN are evaluated by connecting a local network to a 200-km WDM-ring backbone network. Our discussions and demonstrations confirm the impact and feasibility of the proposed hyper-media photonic information network.

This paper presents a queueing analysis method for the M/M/1 queue with service interruptions. The queueing model considered here is applicable to voice/data communication systems, communication swiching systems and so on. Assuming that both on- and off-periods of the server are generally distributed, the steady-state distribution of the number of customers in the system, including one unknown function, is derived by using the supplementary variable technique. The mean number of customers in the system is obtained by approximating one unknown parameter. The proposed approximate formula requires only the first two-moment input parameters, which is simple enough for numerical calculations. Some numerical examples are compared with the exact and simulated results and show good accuracy of the proposed formula for a practical situation.
