On the efficient design of network resilient to electro-magnetic pulse attack—elastic optical network case study

The telecommunication networks have become an indispensable part of our everyday life, providing support for such important areas as business, education, health care, finances, entertainment and social life. Alongside their continuous uninterrupted operation is required while numerous new threats attack scenarios emerge. international security organisations warn against increasing likelihood nuclear weapon or electro-magnetic pulse (EMP) attacks, which can be extremely harmful also transport networks. On that background, we study efficient design network resilient to EMP wherein the protection level provided by application multipath routing military grade bunkers (advanced radiation approaches protecting whole node) implementation. Formally, define problem location, spectrum allocation (BLRSA) in elastic optical (EON). In objective address two criteria - resilience (measured average lost flow per potential attack) usage. For propose integer linear programming (ILP) model dedicated heuristics 1S-RSA 2S-RSA. Then, perform extensive numerical experiments divided into three parts: (i) tuning proposed approaches, (ii) comparison with reference methods, (iii) realistic case EMP-resilient design. analyze benefits costs scheme. Moreover, vulnerabilities topologies attacks identify critical nodes. investigation proves high efficiency shows they allow save up 90% traffic no these types attacks.
