Abstract: Fault-tolerant request routing routes request to service hosts without using a central routing authority to processes each request and without applying a consensus protocol to each request. In order to route requests, a routing authority distributes updated routing tables to request routers or clients while the request routers or clients continue to route requests according to a previous version of the routing table. Each request router or client includes a logical clock and refrains from using the next version of the routing table until receiving an indication to transition its logical clock. The routing authority indicates to a first request router to transition its logical clock to the next moment in logical time and an epidemic algorithm transitions other ones of the request router to the next moment in logical time without direct involvement by the routing authority.

Abstract: We disclose a method for controlling access to an optically switched network, which connects N end-nodes, and is organized into a virtual data plane and a virtual control plane, which both communicate through the same underlying physical optical network. The virtual data plane provides any-to-all parallel connectivity for data transmissions among the N end-nodes, and the virtual control plane is organized as a ring that serially connects the N end-nodes, wherein a control token circulates around the ring. During operation, an end-node in the ring receives the control token, which includes a destination-busy vector with a busy flag for each of the N end-nodes. If the end-node has data to send and the busy flag for the destination end-node is not set, the system: sets the busy flag; commences sending the data to the destination end-node; and forwards the control token to a next end-node in the ring.

Abstract: A switching device includes a plurality of ports and a switching core, which is coupled to transfer data packets between ingress and egress ports. Switching logic maintains a descriptor queue containing respective descriptors corresponding to the data packets that have been received and queued by the ports, and responsively to the respective descriptors, instructs the switching core to transfer the queued data packets between the ports. Port logic, which is associated with each port, is configured, upon receipt of a data packet from the network at the port, to signal the switching logic to place a descriptor corresponding to the data packet in the descriptor queue and, upon identifying the data packet as meeting a predefined criterion, to convey a request to the switching logic, bypassing the descriptor queue, to instruct the switching core to transfer the data packet immediately to an egress port.

Abstract: Two (or more) client devices engage in a chat session. Packets associated with the chat session are numbered using a predetermined pattern. When the packets are received, the receiving client device extracts signals from the packet metadata to determine whether the primary cause of packet loss during transit is network congestion or link losses. Based on the extracted signals, the receiving device sends a control message back to the other client device indicating how one or more chat parameters should be updated. On receiving the control message, the other client device updates the chat parameters accordingly.
