Network controller design for SONATA, a large scale all-optical WDM network

چکیده
This paper describes the network architecture and provides a performance analysis of a passive optical network named SONATA, which has been proposed and will be demonstrated in the context of the European Union ACTS Program. In this nation-wide all-optical network, end-terminals access a single passive routing node via PONs using a TDMA/WDMA access scheme based on slot reservations. The centralized network controller runs resource allocation algorithms to avoid conflicts among end-terminals. Since the resource allocation problem at the network controller can be show to be in general NP-hard, we provide simple heuristic algorithms to solve the problem. The analysis of the algorithms is performed via both analysis and simulation.

PLI-Signal Quality RWA algorithm for Limited Range Wavelength Converter based Translucent Optical Wavelength Division Multiplexed (WDM) Networks
This paper formulates a framework for solving the offline physical layer impairment-routing and wavelength assignment (PLI-RWA) issue in translucent wavelength division multiplexed (WDM) optical networks. For network design, the PLI-Signal Quality Aware RWA (PLI-SQARWA) algorithm is employed that (a) guarantees zero blocking due to signal degradation and wavelength contention and (b) minimizes ...
متن کاملA Novel Protection Guaranteed, Quality of Transmission Aware Routing and Wavelength Assignment Algorithm for All-optical Networks
Transparent All Optical Networks carry huge traffic and any link failure can cause the loss of gigabits of data; hence protection and its guarantee becomes necessary at the time of failure. Many protection schemes were presented in the literature, but none of them speaks about protection guarantee. Also, in all optical networks, due to absence of regeneration capabilities, the physical layer i...

The current paper investigates the influence of packet losses in network control systems (NCS’s) using the model predictive control (MPC) strategy. The study focuses on two main network packet losses due to sensor to controller and controller to actuator along the communication paths. A new Markov-based method is employed to recursively estimate the probability of time delay in controller to ac...
