6. Existing System(contd) It satisfy the needs of user and internet service provider TRUMP Advantage A new traffic management protocol that is distributed, adaptive, robust, flexible and easy to manage. Packet-level simulations show TRUMP behaves well with realistic topologies, feedback delays, capacities, and traffic loads. Disadvantage 1. They are also inflexible in differentiating the control at different links. 2. Convergence is not guaranteed 3. Numerical level simulation is not possible.
