Abstract: A set of routing rules is receiving at a networking device in a data communication network from a controller in the data communication network implemented using the software-defined network architecture. A condition is detected at the networking device. A subset of the set of routing rules is selected in the networking device. The selecting is responsive to the condition. The subset of routing rules is applied in the networking device at a first time such that the networking device uses a first routing rule to route data traffic in the data communication network, and omits using a second routing rule received from the controller to route data traffic in the data communication network. A second subset of routing rules from the set of routing rules responsive to a second condition is applied autonomously at a second time at the networking device.

Abstract: An aspect includes deadlock-free routing on arbitrary network topologies using edge-disjoint sub-networks. A network topology of a network is identified. The network includes a plurality of links between a plurality of switches. Each of the links is identified as an edge. A plurality of edge-disjoint sub-networks is constructed from the network topology of the network by routing configuration logic. The plurality of edge-disjoint sub-networks is formed by edges between the switches such that the edges are disjoint relative to each of the edge-disjoint sub-networks. The switches are configured to route traffic on the network with each route staying entirely within one of the plurality of edge-disjoint sub-networks within the network.

Abstract: An all-optical transmission system includes an optical switch matrix, a plurality of optical components communicating over the optical switch matrix, and a top of rack (ToR) switch coupled to each optical component. Each ToR switch communicates with the optical components and with other ToR switches. The optical component includes a send circuit and a receive circuit with the send circuit having a ToR transceiver to receive data, a multiplexer coupled to the ToR transceiver, a Wavelength Selective Switch (WSS) coupled to the multiplexer, and a circulator coupled to the WSS.
