Abstract: Methods, apparatus, systems and articles of manufacture to reflect routes from a virtual route reflector are disclosed. An example method includes requesting, at a virtual route reflector remote from an autonomous system, topology information and external route information from the autonomous system. The external route information identifies a plurality of border routers through which a remote destination can be reached. The example method also includes selecting, using the topology information, a first path from among a plurality of paths emanating from a selected node in the autonomous system, the plurality of paths exiting the autonomous system at respective border routers of the plurality of border routers. The example method further includes advertising, from the virtual route reflector to a client router in the autonomous system, a route to the remote destination, the route including a first border router at which the first path exits the autonomous system.

Abstract: Techniques described herein generally include methods and systems related to circuit switching in a network-on-chip. According to embodiments of the disclosure, a network-on-chip may include routers configured to pre-reserve circuit-switched connections between a source node and a destination node before requested data are available for transmission from the source node to the destination node. Because the circuit-switched connection is already established between the source node and the destination node when the requested data are available for transmission from the source node, the data can be transmitted without the delay or with reduced delay caused by setup overhead of the circuit- switched connection. A connection setup message may be transmitted together with a memory request from the destination node to facilitate pre-reservation of the circuit-switched connection.

Abstract: The present disclosure describes techniques for hardware acceleration for routing programs. In some aspects communications between a routing determination program and a packet router are monitored in a router, both the routing determination program and the packet router being part of a software layer of the router. The communications include the routing determination program providing configuration data to the packet router. Based on the monitored communications, a packet processor is changed to reflect the configuration data, the packet processor being part of a hardware layer of the router. The packet processor performs packet routing operations of receiving packets, determining the next routers in the paths to the target destinations of the packets, and sending the packets to the next routers independent of the software layer.

This system allows direct and indirect communication between a source node and a destination node. In direct communication, data propagates via links connecting the source and destination nodes. In indirect communication, data is first sent to an intermediate node via links connecting the source and intermediate nodes. The intermediate node sends the data either to the destination node via links connecting the intermediate node and the destination node. A passive device with replaceable plugs connects the plurality of nodes in full mesh. The passive device facilitates setting up and updating a network.
