摘　　要：选路技术是保证网络QoS的一个重要因素。基于蚂蚁网络的QoS选路算法,来源于蚂蚁群落的生物行为特性。这种选路技术存在蚂蚁群数量过多、控制复杂的问题。文中提出了基于较大带宽的业务流呼叫驱动人工蚂蚁发射的新算法,以减少网络中蚂蚁的数量,并使用可后退的、智能型的选路算法,确保较高的呼叫成功率。Routing technology is an important aspect to guarantee QoS of networks.The routing algorithm based on AntNet originates from biological behavior of ant colonies,but there are too many artificial ant colonies in networks and it is difficult to manage.This paper provides a new algorithm which emits artificial ants based on calls with the higher bandwidth requirement.The new algorithm can reduce the colonies of artificial ant and guarantee higher call success probability combined with a smart routing algorithm which can go back to the last node.
