Abstract

In optical networks supporting multicast traffic, an optical tree is established for each request. The structure and efficiency of this tree significantly impact resource utilization. To date, researchers have introduced two types of trees, SPT-RSA and STA-RSA, both of which have certain limitations. This paper investigates routing and spectrum allocation (RSA) strategies in flexible optical networks (EON) for multicast traffic demands. A light tree is constructed for each incoming request, and the SMART-FIT allocation policy is employed to allocate the necessary spectrum efficiently. The proposed algorithm is evaluated against SPT-RSA and STA-RSA in terms of request blocking probability and bandwidth blocking probability. The results demonstrate that the proposed approach outperforms the existing algorithms in both metrics.
