An Overview of Routing and Allocation of Equalized Wavelength or Power Distribution in Optical Network Security

چکیده
Optical networks play an important role in information communication supporting both small-scale and large-scale networks through its capacity of seamless transmission of massive volume of data within a short time period. Some of the issues related to information communication using optical networks are routing, assignment of the wavelength and minimizing lightpath attack radius. By using adequate security measures and routing the lightpaths in an appropriate manner, we can decrease the potential damage like jamming attacks, flooding attacks occurred in the physical layer and we can overcome the congestion problems also. Routing in the optical networks needs to be dynamic as the wavelengths and its parameters are changing frequently. This paper presents a brief survey about the existing approaches in the Routing and Wavelength Assignment (RWA) using Wavelength Division Multiplexing (WDM) and optical cross connect switches which also provides solutions for the security threats in the physical layer of optical fiber networks. Based on the analysis carried out over the existing solutions we are proposing an equalized wavelength or power distribution using Wavelength Division Multiplexing (WDM), optical crossconnect equalization at the network nodes and power equalization placement in order to prevent jamming attacks and reducing LAR with minimum cost.

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...
