Research of Multipath Routing Processes in Software Defined Networks Based on Ant Colony Optimization

Currently, the data in the network is increasing in both size and complexity, while network resources are limited, leading to network management becoming more difficult. Traditional network architectures are becoming increasingly unsuitable for the network requirements to respond to rapidly changing parameters of bandwidth, latency, security, etc. Software defined network (SDN) has become a new approach, changing the current network architecture to meet the needs of network resource management and traffic control. The purpose of the work is to study and analyze the multipath routing processes in the software defined network based on ant colony optimization. The simulation results show that the proposed algorithm is effectively used to find the shortest paths. The paths found can be used at the same time to transmit data, instead of just using a single path. From there, the performance of the network is improved, limiting congestion, reducing latency and packet loss.
