| 摘 要： | 针对智能光网络(ION)中的层次结构，提出了DHBR和DHROG 2种分层路由算法. 2种算法均基于固定层备选路由策略，着重考虑了各层域间链路与网关节点处的资源协调与均衡. 离散事件仿真结果表明，2种算法均可以有效地提高网络性能，得到较低的阻塞率，并具有较好的时间特性.

| Abstract: | The hierarchical routing infrastructure in intelligent optical network(ION) is researched.Two algorithms called dynamic hierarchical balancing routing algorithm(DHBR) and dynamic hierarchical routing algorithm based on optimized gateways(DHROG) are proposed in which the resource coordination,the balance for inter-domain links and the gateway nodes are considered based on fixed alternate hierarchical routing.Simulation shows that the average block probability of the network can be reduced effectively with ac... |
