| Abstract: | The link weight optimization method for MIRA(minimum interference routing algorithm) is proposed with a novel architecture for explicit routing computation.The proposed methods use a combination of centralized and distributed computing methods to deploy the explicit routing algorithm for MPLS traffic engineering system.Link weight is computed by PAWS(policy and weight server).LER(label switch router) executes distributed computing methods of MIRA,computers bandwidth guaranteed explicit routing.Through the treatments,the efficiency and accuracy of explicit routing algorithm are improved,and the scalability of the system is enhanced as well. |
