Virtuelne privatne mreže - moguće rešenje pouzdanih komunikacija / Virtual private networks: Possible solution of reliable communications

U radu su prikazane osnovne karakteristike virtuelnih privatnih mreža (VPN - Virtual Private Networks). Analizirane su VPN mreže na drugom i trećem sloju sistema otvorenog za povezivanje (OSI - Open System Interconnection). Objašnjena je realizacija internet protokola (IP - Internet Protocol) VPN mreže i VPN mreže u okruženju višestruke komutacije labela (MPLS - Multi-Protocol Label Switching). Posebna pažnja posvećena je sigurnosti MPLS VPN mreža, naročito sa stanovišta upotrebe u funkcionalnim sistemima veza, kao što je sistem veza Vojske. / In this paper the basic characteristics of the VPN networks are presented. The VPN networks on the second and the third level of the OSI reference model are analyzed. The realization of the IP VPN and VPN networks within MPLS environment is presented as well. Security in MPLS networks is one of the most important characteristics, especially in military communication systems, which is shown in the second part of this paper.
