Twin Labeled Virtual Private Network Above Multi-Protocol Label Switching Network for VoIP

— Multi-protocol label switching network (MPLS)is implemented in Virtual Private Network (VPN) to effectively fulfill the demands o f Voice Over Internet Protocol (VoIP) services in a secure and effective way. The proposed idea is to differentiate the clients with in a network by adding them to a virtual private network by enabling different t e c h n i q u e s l i k e virtual routing and forwarding system. The need of high security within the network along with better transmission speed for sharing data and information is achieved by enabling Multi-protocol label switching within the network of a big organization. Going Forward, the configurations of the network are controlled by assig ning an IP address to route itself within the network using a unique identity by enabling Open Shortest Path First (OSPF) protocol. The initial proof of the proposed network is built using a simulator commonly known as the GNS3. In which we use the Border gateway protocol (BGP) to create MPLS–VPN network between customer end and edge router in the server end. This established a premeditated network that proves to enhance the virtual routing in an efficient way which is clearly demonstrated by the simulation outputs
