    MPLS VPN
    (UMT, Lahore, 2016) MUHAMMAD SHAHZAD, HAYAT ULLAH and ZAKI NAWAZ
    MPLS is proposed to replace the frame relay technology. MPLS use for forwarding the traffic on the basic of Labels so that effectively increase the efficiency of device and easy to manageable. MPLS give support of load balancing (if two ISP are connected one is active and other is standby but in MPLS we can use both link for traffic). MPLS use for geographical area (connectivity of different sites of same company located at different even countries).MPLS support Quality of service (voice, video etc). Virtual private network can be make in MPLS.MPLS belongs to layer 2.5 layer mid between network (Routing) and data link (Switching) layer. MPLS work for speedy network of labeling increase reliability and easy to manage. MPLS can work for same subnets of sites means every sites contain the same IP address MPLS run between them by creating VPN tunnels through which they can communicate with each other like they are directly connected. Traffic engineering application of MPLS is used for manage the traffic through which you done for specific route passes through specific link of having mention bandwidth if bandwidth increase then not allow the specific route to carry on that specific link. MPLS can be use for ATM on bridge purpose like in banking sector ATM link if ATM one link goes down MPLS have standby link immediately up that standby link. So MPLS have a lot of benefit over other technology in recent years.
