Vojna akademija, Beograd Rezime: 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 Interconnnection). Objašnjena je realizacija internet protokola (IP -Internet Protocol) VPN mreže i VPN mreže u okruženju višestruke komutacije labela

Ključne reči: VPN, VPN na drugom sloju, VPN na trećem sloju, IP, MPLS, zaštita. Summary: 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.
