Research on Load Balancing Algorithm of Multicast Services Based on EON

The spectrum grid of the traditional wavelength division multiplexing (WDM) network is fixed, so it has the shortcomings of low spectrum utilization and poor flexibility. Based on this, elastic optical network (EON) came into being. Compared with the traditional WDM network, the EON has a flexible spectrum grid with high network flexibility and can provide different spectrums for different services. But the EON still has the problem of load balancing. In order to further optimize the EON, this article uses the Least Connections algorithm to solve the EON load balancing problem, taking into account the different server load capacity to improve it. In addition, to further improve the performance of EON, this paper combines genetic algorithm, improved least connections algorithm and ant colony algorithm to propose a new algorithm LC-GAACO. The simulation results show that the LC-GAACO algorithm will consume more optical transceivers while taking into account load balancing, but the network load balancing effect, network spectrum utilization, and blocking rate are better than traditional algorithms.
