Aplicatii in retele virtuale private

Autor/autori: Dr. ing. Stefan-Victor NICOLAESCU

Rezumat: Articolul prezinta o sinteza a principiilor de configurare si de lucru in retele virtuale private, VPN. Sunt puse in evidenta problemele specifice ale retelelor virtuale si se comenteaza protocoalele de transmisie prin tunel a informatiilor. Se subliniaza ca exista mai multe moduri de configurare a tunelurilor si se pun in evidenta protocolul de comutare cu etichete multiple, MPLS, care apare ca cel mai bine adaptat pentru transmisia VPN. Articolul analizeaza mai multe servicii si aplicatii realizabile prin VPN.

Abstract: The paper presents a synthesis of configurations and working in virtual private networks. The specific problems of virtual networks are emphasized and some comments on the tunneling protocols for data transmission are presented. The paper emphasizes that there are some protocols for tunnel configurations. The MultiProtocol Label Switching seems to be the best adapted for VPN transmission. The paper analysis some main services and applications in virtual private networks.
