摘要： Systems and methods for scheduling data for transmission over photonic switches are described herein. In one embodiment, an apparatus is provided that includes a node having M photonic interfaces. The node is configured to transmit a message having R requests. Each one of the R requests is a request to transmit data from the node to another node. R may be greater than M. Additionally or alternatively, each request may include a queue index corresponding to a respective queue in the node. The value of the queue index may be based on both a queue occupancy of the respective queue and a delay parameter.

摘要： Method and apparatus are provided for controlling an interface to a switch, for example a photonic switch. The method comprises communicatively connecting a controller to a source node and to a destination node; receiving from the source node information indicating a status of at least one input queue at the source node; allocating, based on the information, the at least one input queue to at least one interface of the source node; and aligning frames at the destination node when multiple interfaces of the source node are used for transmission of one input queue. Transmission of one input queue is coordinated via multiple interfaces of the source node. An ingress/egress chip for providing an ingress/egress interface to a photonic switch is also provided.

摘要： A method and apparatus for routing received connection demands through a photonic switch having multiple parallel instances of a switching plane is provided. Routing respects the constraint that each cell of the switch accommodates a maximum of one lightpath. Connection demands are routed one at a time via switching plane instances where it is possible without violating the constraint. When a demand cannot be routed, a re-arrangement step is performed. A previously routed demand that conflicts with the blocked demand is identified and de-allocated. The blocked demand is then routed in place of this de-allocated demand, which is now considered blocked. The process repeats until no blocked demands remain. Attempts to route additional demands of lower priority can also be made by checking whether each lower priority demand can be routed given the configuration of the switch to route existing demands.
摘要翻译：提供了一种用于通过具有开关平面的多个平行实例的光子开关来路由所接收的连接需求的方法和装置。路由方面遵循交换机的每个单元最多容纳一个光路的约束。连接需求通过可能的切换平面实例一次一个路由，而不违反约束。当需求不能路由时，执行重新排列步骤。与被阻止的需求冲突的先前路由的需求被识别和解除分配。阻塞的需求然后被路由替代现在被认为被阻止的这种去分配的需求。该过程重复，直到没有阻止需求为止。通过检查每个较低优先权要求是否可以通过交换机的配置路由现有需求，也可以尝试路由更低优先级的附加需求。
