MPLS VPN Tunneling Using IPv4 And IPv6

Parth J. Trivedi, Prof. Rinkal Shah

Abstract :

<p>&nbsp;Advancement and innovation in internet networking field is reaching to remarkable milestones rapidly. So far Frame Relay is being used for exchanging information through internet, Frame Relay uses a packet switching methodology for faster delivery of packets but has much more disadvantages such as higher error rate, no guarantee of data delivery, need of special equipment and protocol dependent. Lately MPLS a label switching technology which ensure faster and guaranteed delivery of data with lesser delays has been in internet networks. MPLS is a protocol independent technology which works on label switching for faster routing and switching compared to ATM and Frame Relays providing flexibility of inter-networks without compromising scalability. MPLS provides a carrier grade transport platform, pseudo wires for separate virtual paths and much more. Implementing MPLS in the core network will reduce the overheads at service providers providing load balance reducing traffic congestion at service stations, pseudo wire paths for different kinds of data can be allotted, Traffic engineering and shaping, security, Backup paths are additional features of MPLS. MPLS can be applicable to ISP&lsquo;s, Large Enterprises, huge Railway networks etc</p>
