In the Internet, Traffic management includes congestion control, routing protocols and traffic engineering.Traffic management is the adaptation of source rates and routing to achieve the goals of users and operators.The end hosts adapt their sending rates to network congestion, and based on that network operators adapt the routing to the measured traffic.Congestion Control is done by source node depending on the ICMP message sent by any intermediate node of the packet delivery path towards the end node.Routing protocols are implemented on the routers for routing purpose.Traffic engineering is an important mechanism for Internet providers seeking to optimize network performance and traffic delivery.As network grows in size and complexity network management needs the optimized protocols instead of existing protocols.There may be a question whether the joint system of congestion control (transport layer) and routing (network layer) is optimal and stable.By using the optimal traffic engineering and optimization model for TCP, the new algorithms can be implemented.The latest algorithms uniting the network and transport layers in a multi-layer approach and can be optimal and maximizes aggregate user utility.In this paper we present various distributed multipath routing protocols which are nearer to optimized and one of them Distributed Adaptive Traffic Engineering(DATE) is the joint system of congestion control and routing.
