 Rezumat
Reţelele virtuale private (VPN) oferă mediului de afaceri o soluţie extrem de atractivă pentru transmiterea securizată a datelor. Totodată, VPN reprezintă şi cea mai eficientă cale de a satisface cerinţele clienţilor care necesita, pe langă transmisii securizate de date, şi capacitate mare de transmitere şi viteză ridicată.
Lucrarea prezintă o analiza a tehnologiilor proprii reţelelor virtuale private şi ale telefoniei prin Internet, cu evidenţierea avantajelor şi dezavantajelor asociate, precum şi a avantajelor şi dezavantajelor telefoniei prin Internet în comparaţie cu telefonia clasică. Studiul de caz pentru sistemul de videoconferință este efectuat pe echipamente dedicate, fiind evidențiate și detaliate toate elementele componente ale sistemului, precum si maniera de configurare.
