Multiprotocol Label Switching (MPLS) was originally designed with the intention of improving the speed with which routers could forward packets in Internet Protocol (IP) networks. Due to significant improvements in packet forwarding, this is no longer an advantage, but the technology has found large-scale industry-wide acceptance because of its greatly widened scope and application. Multiple extensions and enhancements to the protocol make it capable of solving an array of current service provider and customer network requirements for a converged network in an IP dominated world. The chapter considers the use of MPLS for the provisioning of a virtual private network over a shared physical infrastructure, and discusses the logic and functionality of key protocols associated with MPLS. It then goes on to explore the problems, protocols, and possibilities of these technologies in current environments.

Los routers de borde del proveedor de servicios establecen VPNs (Virtual Private Network) realizando el enrutamiento entre los usuarios y la red de núcleo (Core) por medio de Routers Virtuales (VR). Los routers virtuales establecen el enrutamiento a las redes MPLS/VPN/BGP por medio de las tablas VRF (Virtual Router Forwarding), las cuales utilizan el algoritmo de enrutamiento Borde Gateway Protocol (BGP) para sus anuncios. Las sesiones BGP son del tipo malla completa en donde se establecen mayores costos en los anuncios, por ello se realiza un análisis comparativo con rutas reflejadas, obteniendo un 31% de mejora a nivel de los costos del algoritmo, en la configuración de rutas reflejadas en la función de encapsulamiento MPLS (Multiprotocol Label Switching).

Multiprotocol Label Switching (MPLS) is a switching technology. MPLS-TP is a progressive version of MPLS in the field of packet switched data network. MPLS-TP is a high-end technology which implements network methodologies in a transport layer. For managing virtual private network(VPN) services, MPLS is of developing enthusiasm to the service providers (SPs) and furthermore to VPN customers. MPLS-enabled routers allot a few labels to the packets, and in view of these allocated labels it produces sending decisions. The prime expectation after the MPLS technology is to eliminate the need of OSI model data link layered (layer-2) technology i.e. frame relay, Ethernet, asynchronous transfer mode (ATM). This paper gives data about the components of Multi-Protocol Label Switching (MPLS), correlation of MPLS with traditional Routing and Packet Switching, MPLS label format and MPLS operation.

Data communication network, part of the information technology, becomes so important in communicating information and transferring data. Most companies in the world, including companies operating in Indonesia, have used data communication networking technology for their day-to-day operation. However, transferring data through network has some security problems. Therefore, accountants should be familiar with and have knowledge about it in order to ensure high quality work that they provide. Based on IETF – Internet Engineering Task Force a (RFC (Request for Comment)-3031), it is stailea that information technology used to communicate and transfer information as well as data should be efficient and safe.  Multiprotocols Label Switching (MPLS) is a new technology used in virtual private network is one of the solutions in making data transfer efficient and safe.

This exploratory study analyzed the current complications in the Manufacturing organizations for transferring files between two or more sites in-between an organization over an unsecured network communication. Based on the analysis we provide reliable implementation by an appropriate solution to improve and develop the performance of the network communication to help the company to progress the quality of work. The initial phase of the study analyses about Virtual Private Network (VPN) based on the network layers and identifies the underneath difficulties in VPN while data travels over the network in the form of encapsulation and the traffic of the fundamental network. Because of such an encapsulation technique used in VPN, it increases the network traffic which affects the bandwidth of a low-speed internetworking communication. By analyzing various case studies, it was identified Multiprotocol Label Switching (MPLS) technology gives a feasible solution to put the network communication on the right track. It creates secure and reliable connectivity between organization sites and was effectively implemented in the place where slow speed network for connectivity between organizations are found. The recommending this MPLS solution, it helps organizations to share and effectively utilize the servers and service between organizations for secure, reliable and effective communication. Also by considering network security factor as a very significant factor for any network, we have also implemented the Firewall which provides appropriate defense for networks that prevents from internal and external threats. At the same time, the solution also provides support to Wireless LAN Controller (WLC) for providing easy manage and control all wireless access point.     Keywords: Firewall, Multi-protocol Label Switching (MPLS), Servers, Virtual  Private Network (VPN), Wireless LAN Controller (WLC).

VoIP (Voice over Internet) dikenal juga dengan sebutan IP (Internet Protocol) Telephony saat ini semakin banyak digunakan karena memiliki beberapa keunggulan, salah satu diantaranya yaitu tarif yang jauh lebih murah daripada tarif telepon tradisional sehinggapengguna telepon dapat memilih layanan tersebut sesuai dengan kebutuhannya. VoIP dapat mereduksi biaya percakapan sampai 70%. Selain memiliki beberapa keunggulan di atas,VoIP juga memiliki kelemahan yang sangat vital yaitu dari segi keamanan transfer suarakarena berbasis IP, sehingga siapapun bisa melakukan penyadapan dan perekaman terhadap data VoIP. Ganguan yang terjadi pada sistem VoIP ada berbagai macam diantaranya, transferdata yang lewat pada suatu jaringan seperti misalnya dapat disalahgunakan (abuse), dapatdibajak isi data tersebut (sniffing), dan tidak dapat mengakses server dikarenakan server yang kelebihan muatan (Denial of Services).Ada beberapa cara untuk mengamankan komunikasi data VoIP, antara lain, dengan mengamankan jalur yang digunakan pengguna untuk melakukan komunikasi VoIP denganmenggunakan metode VPN (Virtual Private Network) dan juga dapat dilakukan suatu metode kriptografi pada aplikasi VoIP tersebut sehingga data yang dikirimkan dapat dilindungidengan baik. VPN adalah teknik pengaman jaringan yang bekerja dengan cara membuat suatu tunnel sehingga jaringan yang dipercaya dapat menghubungkan jaringan yang ada diluar melalui internet. Titik akhir dari VPN adalah tersambungnya Virtual Channels (VCs)dengan cara pemisahan. Kenyataannya koneksi sebuah end-to-end VPN tergantung dari sebuah nilai dari hubungan daripada titik-titiknya. VPN mempunyai dua metode dalampengamanan yakni IPSec dan Crypto IP Encapsulation (CIPE). Selain itu dapat dipergunakan teknik Kriptografi (cryptography) yang merupakan ilmu dan seni penyimpanan pesan, data,atau informasi secara aman.Sistem VoIP menggunakan VPN ini diharapkan dapat memberikan keamanan transfer data pada jaringan internet maupun intranet.

Now-a-days the significance of security has been greater than before because of the fact that data has been accessed and transferred through public network. The data which has been transferred could be sniffed which may be a loss for us. When data is transferred in to public network we need confidentiality, integration and authentication. In this review paper we will discuss all these factors that keep our data safe enough. In order to provide this factor a site-to-site virtual private network has been designed which provide more security to data and made the public network into private network. The virtual private network hides the source and destination address as well as it also hides the internal network so that our network would be safe enough.
