Abstract :
Virtual Private Network (VPN) which is a technology that connects two or more
different local networks in the encrypted public network (internet). VPN networks without
additional packet security mechanisms can be dangerous because VPN networks use public
networks so that one of them implements Multiprotocol Label Switching Virtual Private
Network (MPLS VPN), which is a combination of two technologies: MPLS and VPN. MPLS
VPN offers a variety of reliability and speed of packet data delivery, it is this that encourages
many companies that have branch offices to use the technology. In this research is used
MPLS-VPN network, to connect two different VPN in order to communicate with each other.
The research method used in this network design is done to simulate MPLS VPN network is
using EVE-NG simulator application. MPLS VPN network there are two data packet
delivery path that is primary or strict path and secondary or loose path. QoS parameters
that are tested are delay, jitter, packet loss and throughput. The simulation is done by using
2 computers and a VOIP server. From the results of measurement and testing on the MPLS
VPN network and without MPLS VPN obtained that when the network has not implemented
MPLS VPN better than after implemented MPLS VPN. Voice and video call services result
in lower value gains than after MPLS VPN implementation. In the MPLS VPN network
obtained the value of QoS when MPLS VPN implemented on two layers of L3VPN and
L2VPN obtained the highest delay value at L3VPN that is equal to 20,578 ms, the parameters
obtained the greatest value obtained 23,421 ms, packet loss for both the second network
obtained the largest obtained by L2VPN is 2.06% and the largest thrughput obtained by
L2VPN is 0.713 Mbps. So it can be concluded that L3VPN is better than L2VPN seen from
the result of QoS parameters obtained.
