Abstract: This disclosure describes techniques that include interpreting information about a smart contract so that the terms of the smart contract can be implemented across a diverse array of consensus networks or blockchain platforms. In one example, this disclosure describes a method that includes receiving, by a first computing device, information describing a smart contract, wherein the first computing device is included within a first plurality of computing devices, each on a first consensus network that maintains a first distributed ledger; performing, by the first computing device and in response to receiving the information describing the smart contract, operations to update the first distributed ledger; and interpreting, by at least one of the first plurality of computing devices, the information describing the smart contract to determine and perform at least one of a plurality of first smart contract operations on the first consensus network.

Abstract: In general, techniques are described for a hierarchical, distributed DHCP system for managing IP address assignment among distributed networks of computing devices. For example, a system may include a central DHCP server configured to manage a plurality of distributed DHCP servers, each distributed DHCP server configured to perform DHCP using IP addresses allocated from a common prefix for a tenant associated with computing devices managed by multiple DHCP servers. The central DHCP server allocates IP addresses to the distributed DHCP servers, e.g., on an on-demand basis from the common pool and may handle concurrent requests for IP addresses from distributed DHCP servers. Each of the distributed DHCP servers may store records for IP addresses and media access control (MAC) addresses for computing devices managed by that distributed DHCP server, and the DHCP servers may send these records to the central DHCP server to facilitate IP assignment coherency.

Abstract: This disclosure describes techniques that include use of a distributed ledger to arrange for and/or initiate provisioning of network services, and also to validate payment for such network services. In one example, this disclosure describes a method that includes modifying, by a computing system, a distributed ledger maintained by a consensus network to implement a smart contract that is configured to generate, in response to receiving a request for network services, a provisioning request; receiving the provisioning request, by the computing system and from a computing device on the consensus network that is executing the smart contract, wherein the provisioning request includes information describing requested network services; and provisioning, by the computing system and based on the information describing the requested network services, network services.

Abstract: The disclosure describes methods and systems for performing time synchronization in a heterogeneous system. In one example, a method includes evaluating, by a computing system, one or more network conditions of a network to determine whether to perform a time synchronization process with a secondary device in the network, wherein the one or more network conditions include a health score for the secondary device, and, in response to determining, based on the evaluation of the one or more network conditions, to perform the time synchronization process: determining based at least in part on a time indication for a clock on a master device and a time indication for a clock on the secondary device, a time synchronization offset for the secondary device; and sending the time synchronization offset for the secondary device to the secondary device in a data packet.

Abstract: The disclosure describes methods and systems for performing time synchronization in a heterogeneous system. In one example, a method includes, for each secondary device of a plurality of secondary devices in a network: determining, by a computing system and based at least in part on a time indication for a clock on a master device and a time indication for a clock on a secondary device in the network, a time synchronization offset for the respective secondary device; collecting, from the respective secondary device, one or more static parameters and one or more dynamic parameters; determining, based on the one or more parameters, a weight to associate with the time synchronization offset for the respective secondary device; determining, based on each of the respective time synchronization offset for each of the plurality of secondary devices and the respective associated weight, a universal time synchronization offset for the network.

Abstract: This disclosure describes techniques for delivering high-accuracy and high-precision clock synchronization in heterogeneous distributed computer clusters. For example, the disclosure describes a synchronization engine that sets efficient clock synchronization processes based on a cluster node's characteristics, pricing, precision, geolocation, and/or cluster topology, while in some cases using a combination of master clock data with internal atomic clocks of computers. The techniques described herein integrate the synchronization engine into a time synchronization process that may provide stability, versatility, precision and cost balance using technical improvements for characterizing timing system delivery channels.

Abstract: Techniques are disclosed for performing time synchronization for a plurality of computing devices without relying upon a minimum measured delay. In one example, processing circuitry obtains time stamp data in accordance with an iteration of a synchronization operation for a timing protocol, wherein the time stamp data describes one or more measured delays for a path between a first computing device and a second computing device, computes a skewness estimate from the time stamp data using a regression analysis, the skewness estimate comprising a frequency difference between a first clock at the first computing device and a second clock at the second computing device, computes an offset estimate between the first clock and the second clock by applying a prediction model to the skewness estimate; and corrects at least one of the first clock or the second clock based at least on the offset estimate.
