Abstract: A connectivity device, such as a switch may consume lesser power by transitioning into stand-by mode in response to a command from an upstream connectivity device, such as another switch. In the stand-by mode the switch may power down circuitry of the switch that handles incoming messages. The switch may be powered up from the stand-by mode by using a PHY or Layer-1 components of the switch.

Abstract: A method for allocating port assignments for transmitting a reserved network stream across a network node comprises determining a cycle time associated with a network node. The method also comprises establishing, for at least one port of the network node, a plurality of virtual layers associated with the cycle time, wherein each of the plurality of virtual layers is divided into 2n equally-spaced slots per cycle (where n>0). The method further comprises receiving a reserved stream request associated with transmission of a reserved stream across the node, and determining a number of slots required to transmit the reserved stream. The method also comprises assigning one or more slots associated with a port of the network node to the transmission of packets associated with the reserved stream based on the determined number of slots. The method further comprises transmitting the stream according to the slot assignment associated with the port of the network node.

Abstract translation: 用于分配用于通过网络节点发送保留网络流的端口分配的方法包括确定与网络节点相关联的周期时间。 所述方法还包括为所述网络节点的至少一个端口建立与所述周期时间相关联的多个虚拟层，其中所述多个虚拟层中的每一个虚拟层每个周期被划分成2n个等间隔的时隙（其中n> 0 ）。 所述方法还包括：接收与所述节点之间的保留流的传输相关联的保留流请求，以及确定发送所述预留流所需的时隙数。 该方法还包括基于所确定的时隙数量，将与网络节点的端口相关联的一个或多个时隙分配给与保留流相关联的分组的传输。 该方法还包括根据与网络节点的端口相关联的时隙分配来发送流。
