Elastic Optical Networks (EON) have emerged as a promising solution to meet the demands for flexible and high-capacity communication. However, due to spectral contiguity and continuity constraints, the efficient allocation of resources, such as bandwidth, in EONs remains a challenging task, especially for multicast connections. Indeed, in dynamic traffic scenarios, frequent establishment and teardown of requests lead to the formation of isolated spectrum fragments that cannot be allocated to other requests. Several reallocation approaches exist to aggregate these fragments by reconfiguring already established connections in the network to accommodate new connection requests. All these approaches aim to minimize disruptions for users by minimizing the number of reconfigured connections in the reallocation process. We propose a new approach called Dynamic Bandwidth Reallocation for Multicast Connections (RDBM), which is specifically designed for multicast connections. The RDBM algorithm primarily aims to minimize disruptions during the process of reallocating bandwidth for multicast connections while reducing the blocking probability for dynamic multicast traffic.

Abstract
Elastic Optical Networks (EON) have emerged as a promising solution to meet the demands for flexible and high-capacity communication. However, due to spectral contiguity and continuity constraints, the efficient allocation of resources, such as bandwidth, in EONs remains a challenging task, especially for multicast connections. Indeed, in dynamic traffic scenarios, frequent establishment and teardown of requests lead to the formation of isolated spectrum fragments that cannot be allocated to other requests. Several reallocation approaches exist to aggregate these fragments by reconfiguring already established connections in the network to accommodate new connection requests. All these approaches aim to minimize disruptions for users by minimizing the number of reconfigured connections in the reallocation process. We propose a new approach called Dynamic Bandwidth Reallocation for Multicast Connections (RDBM), which is specifically designed for multicast connections. The RDBM algorithm primarily aims to minimize disruptions during the process of reallocating bandwidth for multicast connections while reducing the blocking probability for dynamic multicast traffic.
