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.

The paper must have abstract. The rapid growth of networks base on IP, and the current challenge posed by the technological deployment of IPv6 and annexed applications, challenges that must confront the Internet Service Provider and have stimulated the development for rigorous researches on the topic. The Internet Service Providers ISP offer infrastructure for implementation of virtual private network VPN, where is fundamental the definition of routing schemas between the border route of client CE and the provider PE. In this sense, have been proposed different schemas where the new protocols as Open Short Path First version 3 OSPFv3 have a key role. In the context of VPN, the routing protocol BGP is used to distribute the client’s path, the multi-protocol label switching MPLS is used to send the information packages through the network core in tunnel mode. Originally, only IPv4 was supported and expanded after support OSPFv2 and VPN IPv6. Based on the new specifications in order to support OSPFv3 as a routing protocol PE-CE and the current technological infrastructures begin the process of IPv6 deployment, these elements driving this research which evaluate the performance of routing protocol OSPFv3 on border scenarios MPLS/VPN/IPv6.

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) 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.
