摘要： A communication system which consists of several modules—operating in parallel on segments of a packet—to increase speed and handling capacity. One module acts as master, the others are slave modules controlled by control signals derived by the master module. It is important that in each module the data segment and the respective control signal of each packet are correctly synchronized, because in large systems the data paths carrying packet segments and the control signal paths may have substantially different delays. The invention provides for measurement of the propagation delay differences and for introducing a controlled delay in each slave module, so that data segments and control signals can be correctly correlated by delaying either the one or the other. Synchronization packets are transmitted besides normal data packets, for obtaining time stamps which are used to determine the delay difference.

摘要： A method for selecting packets to be switched in a collapsed virtual output queuing array (cVOQ) switch core, using a request/acknowledge mechanism is disclosed. An egress location for an ingress port is selected based on degrees of freedom for the selection mechanism. The degree of freedom can be derived from the collapsed virtual output queuing array by determining a number of egress locations to which an ingress port may send packets and determining a number of ingress ports from which an egress location can receive packets. Analyzing all the queued packets for assignment to an egress location, starting with a lesser degree of freedom and ending with a greater degree of freedom provides efficient switching allocations and acknowledgements.

摘要： A method and a system to adapt the load balancing of the incoming traffic over the planes of a parallel packet switch (PPS) on the basis of the monitoring of requests and acknowledgments exchanged between ingress port adapters and arrays of collapsed virtual output queues (cVOQ) situated within the plane switch cores is disclosed. According to the invention, at least one counter is associated, in each ingress port-adapter, to each individual switching plane or device to be monitored. Each of these counters is incremented when a request is sent to the corresponding individual switching plane or device and decremented when an acknowledgment is received from this individual switching plane or device. When the range of values taken by the counters of a same ingress port-adapter reaches a predetermined threshold, less (or none) incoming traffic is further transmitted to the individual switching plane or device associated to the higher value counter. An alarm signal is possibly raised too e.g., for replacing the defective individual switching plane or device.

摘要： A method for selecting packets to be switched in a collapsed virtual output queuing array (cVOQ) switch core, using a request/acknowledge mechanism. According to the method, an efficient set of virtual output queues (at most one virtual output queue per ingress adapter) is selected, while keeping the algorithm simple enough to allow its implementation in fast state machines. For determining a set of virtual output queues that are each authorized to send a packet, the algorithm is based upon degrees of freedom characterizing states of ingress and egress adapters. For example, the degree of freedom, derived from the collapsed virtual output queuing array, could represent the number of egress ports to which an ingress port may send packet, or the number of ingress ports from which an egress port may receive packets, at a given time. Analyzing all the ingress ports holding at least one data packet, from the lesser degree of freedom to the greater degree of freedom, the algorithm determines as many virtual output queues as possible, in the limit of the number of ingress ports (an ingress port may send only one packet per packet-cycle).
摘要翻译：一种用于使用请求/确认机制来选择在折叠虚拟输出排队阵列（cVOQ）切换核心中切换的分组的方法。根据该方法，选择一组有效的虚拟输出队列（每个入口适配器最多有一个虚拟输出队列），同时保持算法足够简单，以允许其在快速状态机中实现。为了确定每个被授权发送分组的一组虚拟输出队列，该算法基于入射和出口适配器状态的自由度。例如，从折叠的虚拟输出排队阵列导出的自由度可以表示入口端口可以发送分组的出口端口的数量，或出口端口可以从其接收分组的入口端口的数量，给定时间分析至少一个数据包的入口端口，从较小的自由度到较大的自由度，该算法在入口端口数量的限制中尽可能地确定尽可能多的虚拟输出队列（入口端口可能每个分组周期只发送一个分组）。
