Graph database based recommender system cluster architecture is described. The system is part of the VAS platform for smooth ads embedding to the mobile outgoing call progress phase. The software has to be deployed such way to has access to mobile operator central switching system. Two main hardware/software segments are defined: user data cluster owned by mobile operator and advertisement data cluster. The first one is very critical, as the information security object but the second segment has to be opened to multiple ads agencies. The problem is to support the platform necessary security level in this case. In the paper the new SDN based solution to interconnect two independent parts is proposed. Instead the particular VPN using the new method of permanent connection is described. The Fast IP Hopping protocol insulates the segments one from other using SDN implementation. The protocol based on the random IP address switching during every TCP session. The new quality of data access leads to high level of the system information security.
