“…Independently in [7] and [8] it was proved that RWA problem is N P-complete. Formulations proposed in the literature ( [9], [10], [11], [12], [13], [14], [15], [16], [17], [18], [19], [20]) differ from formulation proposed in the following in terms of graph construction. Namely, in this paper it is assumed that each λ channel constitutes separate edge in the network graph.…”

Development of sophisticated photonic transmission systems enabled evolution of photonic data transport networks towards cost-efficient and energy-efficient platforms capable to carry enormous traffic. Given access to technologically advanced equipment, network operator faces a series of decision problems related to how to efficiently use this technology. In this paper, we propose a functional model of modern photonic network with wavelength division multiplexing (WDM). Proposed functional model is a basis for formulating corresponding flow design problem in terms of mathematical programming.

“…In [4] and [5], the expanded version of which is [6], the authors examined path and link protection, as well as restoration, in physically impaired optical networks under single-link failures. In order to quantify the resilience of these algorithms to failures, a new metric called the vulnerability ratio was defined [4], besides the standard measure of blocking probability.…”

“…The wavelength division multiplexing (WDM) technique divides tremendous bandwidth of an optical fiber into many non-overlapping channels (WDM channels) called wavelengths. This event is called quality of transmission (QoT) or physical blocking [2]. Therefore the WDM optical networks are considered as a suitable choice for exponential growth of broadband users and emerging bandwidth-intensive applications such as video on demand (VoD).…”
