摘要： A method of assigning capacity and routing flow in a bi-directional line switched SONET ring based upon ring topology and demand data defines for each pair of links of the ring a two-edge cut. Each two-edge cut divides the ring into two sets of nodes. For each two-edge cut, the capacity assignment method calculates a demand equal to the sum of all demands between nodes on opposite sides of the two-edge cut. The capacity assignment method then determines the maximum demand and sets the capacity of each link equal to one-half the maximum demand plus one-half of one demand unit. The flow routing method of the present invention calculates a cut difference for each two-edge cut. A critical cut is a two-edge cut having a cut difference equal to or less than one. If there is a critical cut with demands greater than zero on the same side of the critical cut, the method performs a first processing routine. If there is no critical cut with demands greater than zero on the same side of the critical cut, the method performs a second processing routine. The flow routing method performs the first or second processing routine until the occurrence of a terminating condition.
摘要翻译：基于环形拓扑和需求数据在双向线路交换SONET环中分配容量和路由流的方法为环的每对链路定义两边缘切割。每个两边切割将环分成两组节点。对于每个两边切割，容量分配方法计算等于两边切割相对侧的节点之间的所有需求之和的需求。然后，容量分配方法确定最大需求，并将每个链路的容量设置为等于最大需求的一半加上一个需求单元的一半。本发明的流程布置方法计算每个两边切割的切割差。关键切割是具有等于或小于1的切割差的两边切割。如果在临界切割的同一侧存在要求大于零的关键切割，则该方法执行第一处理程序。如果在临界切割的同一侧没有要求大于零的关键切割，则该方法执行第二处理程序。流程路由方法执行第一或第二处理例程直到发生终止条件。

摘要： A method and system for reducing congestion of real time data traffic on a multimedia communications network having a traffic control mechanism. The method comprises of first extracting from data traffic in the multimedia communications network information regarding congestion of the multimedia communications network. This extraction is performed by a network of monitors. Secondly, congestion is regulated by a central server which receives network information from the monitors and utilizes the network information to analyze congestion status and communicate instructions to the multimedia communications network to reduce congestion.
