  • Patent number: 11082203
    Abstract: Various embodiments relate to a method for accelerating blockchains, the method comprising the steps of waiting for an event to occur, receiving a block, determining whether the block is valid, adding the block to a block tree, determining whether the block is a singular candidate, starting a timer for the block, determining whether the timer has expired for the block, determining whether the block is still singular after the time has expired for the block and processing the singular block.
    Type: Grant

  • Patent number: 9979628
    Abstract: The invention is directed to providing cloud-based services using dynamic network virtualization. Embodiments of the invention provide a cloud-based service over a system that has a dynamic network virtualization architecture. The architecture includes a set of distributed forwarding elements with centralized control, and at least one virtual machine that is bound to one of the forwarding elements. These features enable the virtual machine to be migrated across a wide area network while maintaining its original IP address and service continuity.

  • Patent number: 9843535
    Abstract: Various exemplary embodiments relate to a method for processing data packets by a first-hop switch in a data network, including: receiving a first data packet associated with a flow; determining whether the flow associated with the first data packet is found in a flow table in the first-hop switch; modifying the first data packet by replacing a packet header field with flow definition information; and transmitting the modified first data packet based upon the flow definition information.

  • Publication number: 20170171084
    Abstract: Various exemplary embodiments relate to a routing device used for routing via a valiant load balanced (VLB) intermediate node from a source node i, to a destination node j, the device including a memory, and a processor configured to: for each pair of nodes, (ij), find a cost of using node k?i as the Shortest Route (SR); for each node i, compute a cost ?(i) of using node k as the VLB intermediate; and compute a node i* that has the minimum ?(i) value.

  • Patent number: 9641459
    Abstract: Various embodiments relate to a method, network node, and non-transitory machine-readable storage medium including the following: receiving a packet; evaluating a flow processing table comprising a plurality of rules to determine whether a rule of the plurality of rules is applicable to the received packet, wherein: a rule of the plurality of rules includes a matching rule that identifies one or more flows to which the rule applies and at least one action that identifies at least one action to be taken when the rule applies; generating a new rule to be added to the flow processing table when the after failing to identify a rule of the plurality of rules as applicable to a received packet, including: evaluating at least one flow rule generation table to identify a first set of packet header fields and a set of processing actions; installing the new rule in the flow processing table.
