Abstract

Along  with  the  development  of  bandwidth consuming  services,  fiber  optic  is  being  widely  used, especially  in  the  metro  core  networks.  Many  solutions have  been  proposed  for  designing  optical  network topology.  However,  these  solutions  designed  networks with  a  lot  of  fiber  redundancy.  This  paper  proposes  a solution for designing physical topology of optical metro core  networks with the  objectives of (i) ensuring traffic requirements  between  the  network  nodes,  (ii) minimizing  fiber  cost,  and  (iii)  assuring  the  network survivability.  The  numerical  results  show  that  the proposed  solution  satisfies  those  objectives  and  save more fiber than existing solutions.
