    ABSTRAKSI: Video streaming merupakan suatu layanan yang memungkinkan sebuah server untuk mengirimkan video ke beberapa user yang berada pada suatu jaringan. Sebagai contoh layanan video streaming dapat dimanfaatkan untuk long distance learning. Untuk menyediakan layanan long distance learning dibutuhkan suatu jaringan yang dapat menjaga privasi client dan menyediakan jaminan QoS. Hal ini dapat diatasi dengan teknologi tunneling pada jaringan Virtual Private Network (VPN). Tetapi tunneling ini memiliki kelemahan karena kompleksitas jaringan dan mahalnya perangkat yang digunakan. Sehingga lahirlah teknologi Virtual Private LAN Service (VPLS) yang dapat mengatasi masalah tersebut. Dengan penambahan teknologi multicast pada VPLS diharapkan dapat meningkatkan QoS layanan yang bersifat point-to-multipoint seperti video streaming. Pada tugas akhir ini dilakukan pengujian jaringan Multicast VPLS untuk layanan video streaming. Skenario pengujian yang dilakukan antara lain untuk melihat perbandingan performansi dari jaringan OSPF dan VPLS, dan pengaruh implementasi multicast pada VPLS, pengaruh variasi bandwidth, variasi bitrate, dan variasi jumlah client yang mengakses layanan video streaming. Dari hasil pengujian dan analisis implementasi sistem Multicast VPLS didapatkan hasil yaitu jaringan VPLS memiliki QoS yang lebih baik daripada jaringan OSPF karena dapat mengurangi delay sampai 20.03%, meningkatkan throughput sampai 23.13%, dan mengurangi packet loss sampai 79.91%. Penambahan teknologi multicast terbukti dapat meningkatkan performansi jaringan VPLS yaitu dapat mengurangi delay sampai 25.66%, meningkatkan throughput 34.27%, tetapi packet loss yang dihasilkan oleh multicast lebih besar yaitu memiliki selisih sampai 3.54% dibandingkan unicast. Kemudian bandwidth, bitrate, dan juga jumlah client yang mengkases layanan video streaming terbukti mempengaruhi performansi dari jaringan multicast VPLS untuk layanan video streaming. KATA KUNCI: QoS, MPLS, VPLS, Multicast, TunnelingABSTRACT: Video streaming is a service that allows a server to send video to multiple users in a network. For example, video streaming services can be used for long distance learning. To provide long distance learning requires a network that can maintain client privacy and provide QoS guarantees. This can be overcome by tunneling on the network technology of Virtual Private Network (VPN). But this has the disadvantage of tunneling network complexity and high cost of the device used. Thus was born the technology of Virtual Private LAN Service (VPLS) which can solve the problem. With the addition of multicast in VPLS technology is expected to improve the QoS services that have point-to-multipoint characteristics such as video streaming. In this final project, Multicast VPLS network for video streaming service is tested. Scenario of the testing is conducted, among others, to compare the performance of the OSPF network and VPLS, and the effect of implementation of multicast in VPLS, the influence of variations in bandwidth, bitrate variations, and variations in the number of clients that access the streaming video service. From the results of the testing and analysis of system implementation Multicast VPLS, VPLS network is obtained which has a better QoS than OSPF network because it can reduce the delay up to 20.03%, increase throughput up to 23.13% and reduce packet loss up to 79.91%. The addition of multicast technology is proven to increase the performance of the VPLS network can reduce the delay up to 25.66%, increase throughput up to 34.27%, but the packet loss generated by multicast is larger that has up to 3.54% difference compared to unicast. Then the bandwidth, bitrate, and also the number of clients that access a streaming video service shown to affect the performance of multicast VPLS network for video streaming service.

    Virtual Private LAN Service is already very popular among the enterprise industry which is a point to point network or multipoint to multipoint l2VPN service, VPLS provides transparent bridge between customers connected to geographically dispersed locations delivered via MPLS backbone by utilizing features such as MPLS Fast reroute and traffic engineering. Redundant paths can be applied to the VPLS service on the access side and backbone to maintain link performance that aims to minimize down time during network fails on the VPLS service. In this research, the implementation of redundant path using RSTP to prevent forwarding loop switching network in VPLS service to protect end-to-end data traffic with VPLS mesh-pseudowire and spoke-pesudowire with RSTP is the most optimal result compared to STP and build reliable network System with high performance for use in modern industry

    On forwarding state control in VPN multicast based on MPLS multipoint LSPs

    This work is at: 2012 IEEE 13th International Conference on High Performance Switching and Routing took place June 24-27,2012 in Belgrade, Serbia. Web to event: http://hpsr2012.etf.bg.ac.rs/index.phpThe demand for multicast-capable VPN services, like Virtual Private LAN Service (VPLS), has grown quickly in the last years. In order to save bandwidth, MPLS point-to-multipoint LSPs could be used, but the VPN-specific state information to be handled inside the network may exceed the capacity of core nodes. A well-known solution for this is to aggregate the multicast/broadcast traffic of multiple VPNs into shared p2mp LSP trees. In shared trees, although some bandwidth is wasted because a fraction of the packets are delivered to non-member leaves (either not in the VPN broadcast or multicast group), there is wide working range where a good state vs. bandwidth trade-off is achieved. In this paper we enhance and improve previous works that analyze this trade-off. We propose new techniques for multicast traffic aggregation of VPNs in MPLS-based networks, with the objective of observing the behavior of the aggregation philosophy for different aggregation degrees, which should be very useful for network design and deployment purposes. We assess the aggregation heuristics over different reference networks and VPN geographic distributions. Simulations give a quantitative indication of the relevance of intelligent aggregation, of geographical distribution and group sizes.The work described in this paper was carried out with the support of MEDIANET PRICIT 2009/TIC-1468, from the Community of Madrid; and Fundación Carolina, Spain.Publicad

    This article gives an overview of the current practical approaches under study for a scalable implementation of multicast in layer 2 and 3 VPNs over an IP-MPLS multiservice network. These proposals are based on a well-known technique: the aggregation of traffic into shared trees to manage the forwarding state vs. bandwidth saving trade-off. This sort of traffic engineering mechanism requires methods to estimate the resources needed to set up a multicast shared tree for a set of VPNs. The methodology proposed in this article consists of studying the effect of aggregation obtained by random shared tree allocation on a reference model of a representative network scenario.Publicad

    Virtual closed networks: A secure approach to autonomous mobile ad hoc networks

    Get PDF
    The increasing autonomy of Mobile Ad Hoc Networks (MANETs) has enabled a great many large-scale unguided missions, such as agricultural planning, conservation and similar surveying tasks. Commercial and military institutions have expressed great interest in such ventures; raising the question of security as the application of such systems in potentially hostile environments becomes a desired function of such networks. Preventing theft, disruption or destruction of such MANETs through cyber-attacks has become a focus for many researchers as a result. Virtual Private Networks (VPNs) have been shown to enhance the security of Mobile Ad hoc Networks (MANETs), at a high cost in network resources during the setup of secure tunnels. VPNs do not normally support broadcast communication, reducing their effectiveness in high-traffic MANETs, which have many broadcast communication requirements. To support routing, broadcast updates and efficient MANET communication, a Virtual Closed Network (VCN) architecture is proposed. By supporting private, secure communication in unicast, multicast and broadcast modes, VCNs provide an efficient alternative to VPNs when securing MANETs. Comparative analysis of the set-up overheads of VCN and VPN approaches is provided between OpenVPN, IPsec, Virtual Private LAN Service (VPLS), and the proposed VCN solution: Security Using Pre-Existing Routing for MANETs (SUPERMAN)
