Internet is not a single network.The Internet is a collection of netw orks, each controlled by different administrations. Traffic engineering is an important mechanism for Internet network providers seeking to optimize network performance and traffic delivery. Routing optimization plays a key role in traffic engineering, finding efficient routes so as to achieve the desired network performance. BGP is the de facto protocol used for inter-autonomous system routing in the Internet. BGP has been proven to be secure, efficient, scalable, and robust. In proposed introduced A MPLE ¨C an efficient traffic engineering and management system that performs adaptive traffic control by using multiple virtualized routing topologies in MT-BGP. The proposed system contains three complementary co mponents: offline link weight optimization that takes as input the physical network topology and tries to produce maximum routing path diversity across multiple virtual routing topologies for long term operation through the optimized setting of link weights in BGP (Border Gateway Protocol) with admission traffic control algorithm. In our proposal, AMPLE (Adaptive Multi-toPoLogy traffic Engineering), a holistic system based on virtualized BGP routing topologies for dynamic traffic engineering. This paper also concentrates creates new path with help of ADC algorithm. This scheme allows a network to operate in the region of low delay, no packet loss and high throughput
