Performa Protokol Routing OSPF dan BGP pada Jaringan VOIP MPLS dengan Tunelling L2TP/IPSec
Voice communication can be achieved through IP-based networks, be it Internet, Intranet or Local Area Network. Multiprotocol label switching (MPLS) is a convergence of connection-oriented forwarding techniques and Internet routing protocols. This paper discusses the performance of OSPF routing protocols on MPLS VPN-based VOIP networks. The routing protocol applied to this research is Open Shortest Path First (OSPF). The VPN used in this research is L2TP / IPSec. MPLS VPN network is built using three LSR routers and two LER routers. The LSR router is responsible for carrying out packet forwarding while the LER router is responsible for adding or removing labels on packets that go to or leave the MPLS domain. L2TP / IPSec is responsible for securing VOIP communication channels by tuning. Evaluation is done by measuring the quality of VOIP service either without using MPLS or by using MPLS VPN. Based on the research results can be concluded that with the application of VPN on MPLS network able to improve the security of communication channel on VoIP network.
