Transparent optical network dimensioning for self-organizing routing

While transparent optical networks become more and more popular as the basis of the next generation Internet (NGI) infrastructure, such networks raise many security issues, which do not exist in traditional optoelectronic networks. The existing protection schemes which rely heavily on fault detection with the use of network monitoring performed by optoelectronic conversion at the switching nodes, is not sufficient to provide security assurance for all optical networks that lack the massive use of optoelectronic monitoring and require timely protection from malicious sabotage as well as inadvertent faults. In order to increase the security of future networks, they will need to use reactive mechanisms and self-organize through multipath routing (MPR) to protect themselves from potential failures caused by malicious new attacks and ordinary reliability problems. In this paper we are proposing a method for network dimensioning when self-organizing routing as MPR is used as an instinct immediate network reaction to failures and attacks in transparent networks.
