MPLS is the core of any service provider in the world. Almost all the ISPs uses MPLS as its backbone technology to take data from one provider edge to other provider edge. Benefits that MPLS brings for the ISPs are making other competitive technologies of MPLS fade way in a short time and made MPLS so popular. Some of the benefits which makes it a clear winner is that it makes the core of ISP totally BGP free and the ability to create Layer 2 and Layer 3 VPNs. Internet is rising at a very rapid pace and millions of internet enabled devices are connected with the internet every day,With the advent of IOT and cloud, it is getting more fast and contains different challenges to the ISP engineers. QoS and Traffic engineering are some of the challenges that ISP faces with new traffic types like Voice, Video, Cloud, IoT etc. This paper explains the importance of MPLS in ISP network and describes how MPLS plays an important role in taking the traffic from source to destination on the internet when traffic moves within ISP. Different QOS models are compared and a new policy is proposed which can be used in large scale ISPs to have much better traffic management than before. This paper explains a method with which different types of traffics can be transmitted from ingress provider edge to egress provider edge in best possible manner.
