摘要： A network node includes a system enabling high-speed protection switching of traffic between respectively associated working and protection channels of a communications network. The node comprises a multi-stage switch fabric, an interface, and a toggle. The multi-stage switch fabric has a first stage including a respective plurality of stage-1 switch elements. The interface is operatively coupled to a set of one or more stage-1 switch elements, and is adapted to aggregate the working and protection channels of the communications network on a selected one of the set of stage-1 switch elements. Finally, the toggle is adapted to control the selected stage-1 switch element to map traffic between a middle stage of the switch fabric and a selected one of the working and protection channels.

摘要： An automated method of detecting, and provisioning connections between interconnected nodes in a consolidated network element involves sending messages between the nodes. The messages are inserted into data frames sent from respective transmit ports through inter-node links, to respective receive ports. The messages contain information used to provision the receive ports at which they are received, and information for identifying equipment that generated, transmitted, and conveyed the message, respectively, so that the connectivity of the interconnected nodes can be verified.
