IP network optimization by software defined networks

Nowadays IP network optimization is one of the main priorities of service provider, and here Software Defined Networks (SDN) integration together with corporate network infrastructure is a very promising approach. This work is concerned with a problem of ARP protocol using under 2nd layer IP network operation and optimization of those networks by solutions based on SDNs. We demonstrated ability of ARP server integration under particular network infrastructure based on SDN. This ARP server may to reduce risks of ARP message spoofing, and therefore it improves network infrastructure security and fault tolerance. Optimization of broadcast messages mailing also affects to access control and segmentation over one broadcast domain. It is an additional tool for network management. In addition, we considered a positive trend of ARP server using with SDN solutions.
