    • In a free space communication network in which different communication nodes are linked together by directed beams, a method for dynamically configuring the topology of the network allows the transmission directions of the communication nodes to be autonomously changed to communicate with a new node as dictated by the needs of the network. Moreover, the nodes can be switched from directional to broadcast and back again on an as-needed basis. The network consists of a topology that can be rapidly and physically reconfigured as required to provide multiple connectivity, a desired quality of service, or to compensate with the loss of communication links between nodes. The loss of direct communication between any two nodes in an optical network can occur because of obscuration of the atmospheric path between the two nodes. The directed beam which provides the communication channel between the two nodes can, in this situation, be steered to direct its energy towards another accessible node.
    • 在通过定向波束将不同的通信节点链接在一起的自由空间通信网络中,用于动态地配置网络的拓扑的方法允许通信节点的传输方向被自主地改变以与新的节点进行通信,如 网络需求。 此外,节点可以根据需要从方向切换到广播,并重新进行重传。 该网络包括可以根据需要快速和物理地重新配置以提供多个连接性,期望的服务质量或者为了弥补节点之间的通信链路的损失而进行补偿的拓扑。 由于两个节点之间的大气路径的遮蔽,可能会发生光网络中任何两个节点之间的直接通信丢失。 在这种情况下,提供两个节点之间的通信信道的定向波束被引导以将其能量引向另一可访问节点。
