The client request must be redirected to the most appropriate one among these replica servers. In this paper, we proposed Ant Colony Optimization (ACO) based routing algo­rithm to solve this problem. The </span><span lang="EN-US">ants in </span><span lang="EN-US">ACO-based routing algo­rithm will release phero­mone when </span><span lang="EN-US">they</span><span lang="EN-US"> go through the path. The routing decision is based on the cumulative pheromone of the path. The ACO-based routing algorithm not only can find the most appropriate path but also can suit for dynamic topology. When the topology changes frequently, the ACO-based routing algorithm will always find a optimized path. The simulation results show that the ACO-based routing algorithm can achieve higher performance than the other mechanisms.</span></p> ER -
