Transport network optimization methods of mobile operators in Ukraine

This work presented simplified transport network topology of the mobile operator with excretion of Ukraine regional centers. On its basis three-tier network architecture RRS over OTN over DWDM was built, which aims to minimize the total bandwidth for each routing and switching node. The proposed control method of transport network provided by the use of virtual transport switches OTS to create SDN-transport network, which will provide direct control of the backbone mobile operator network.
