In this paper, we focus on the design and analysis of a torus-based backbone architecture which targets to meet both the low delay and high reliability requirements of avionic time-critical communications. Reliable optical connection between arbitrary source-destination pairs is proposed by enabling four non-overlapping lightpaths between the source and destination, which makes the network tolerant...
Communication systems for use in commercial aircrafts are becoming increasingly complex and bandwidth intensive to meet the needs of multimedia users, as well as perform system management functions. The various avionics sub-systems have varied requirements for services that generate a wide range of traffic patterns. Wavelength Division Multiplexing (WDM) provides a robust way to offer such services,...
This paper documents the early efforts to create a fiber optic networking prototype for naval avionic systems, based on the scalability and determinism specified by the SAE. We propose a priority-based ring-hybrid WDM LAN architecture based on the ring-ring approach. The ring-ring architecture consists of a global ring, where each controller is assigned a WDM wavelength at which it can receive incoming...
In this paper, we consider the problem of determining primary and backup paths for survivable optical wavelength-division multiplexed mesh networks. We propose a distributed routing mechanism, which is called Least Resource Consumption Routing, that tries to minimize the combined cost of the primary and the backup paths. The proposed cost model includes the effect of various factors such as mean load,...
In this paper, we consider a circuit-switched optical wavelength division multiplexed (WDM) network that offers protection services to the connections established in the network. A dynamic traffic model, where connection requests arrive based on some stochastic arrival process, is considered. In earlier work, the notion of partial protection was introduced for a WDM network with sub-wavelength capacity...
In this paper, we consider the problem of traffic grooming in optical wavelength division multiplexed (WDM) mesh networks under static traffic conditions. The objective of this work is to minimize the network cost and in particular, the electronic port costs incurred for meeting a given performance goal. In earlier work, we have shown the benefits of limited grooming switch architectures, where only...
