Abstract: A method for controlling packet routing in a network includes identifying segment identifications (IDs) for a number of switches and arranging a first number of the segment IDs into a multi-protocol label switching (MPLS) label field. The method further includes identifying an output port of a respective one of the number of switches located along a network path between source and destination nodes. The switches may route the packet based on corresponding ones of the segment IDs in the MPLS label field. In performing this routing operation, each switch may modify the MPLS label field with remaining ones of the segment IDs that have been shifted in position and padded with zeros, after the segment ID corresponding to the switch has been popped from the MPLS label field. The method therefore presents a technique for performing segment routing through network equipment designed to support MPLS routing.

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.

Abstract: Various embodiments relate to a method for managing information in a database. The method includes injecting a transaction into a first blockchain and injecting the transaction into a second blockchain, where the first blockchain and the second blockchain are in a same blockchain network. The first blockchain processes the transaction based on a first set of rules and the second blockchain processes the transaction based on a second set of rules different from the first set of rules. The second blockchain is a private blockchain that excludes one or more participants of the first blockchain.
