An agent-based routing system for QoS guarantees

This paper describes a new agent-based routing system (ARS) for a datagram network. The ARS supports QoS routing, resource reservation, and admission control functions using ant-like agents. The ARS works under the condition that every node in a network supports the weighted fair queueing algorithm and that network users require two service class deliveries: datagram and real-time flow. The ARS efficiently allocates network resources according to user requests. Simulation results show that more than 70% of network resources are effectively utilized and less than 10% of the resources are unnecessarily reserved when the load of user requests exceeds the network´s capacity
