Adaptive session reliability over multiple transports
Methods, systems, and computer-readable media for providing reliable switching between different transport protocols (e.g., TCP and UDP) are presented herein. In some embodiments, a computing platform may stop transmission over a transport protocol. Subsequently, the computing platform may synchronize buffers between a client and a host.

In some embodiments, when establishing an initial connection between a client and a host, connections may be attempted in parallel over multiple transport protocols. After a connection over a first transport protocol is established, if a connection is later established over a second transport protocol, the connection may be transitioned to the second transport protocol. Also, ticketing semantics may be preserved in the switch between the different transport protocols. |

Asset synchronization systems and methods
The present invention relates to IoT devices existing in a deployed ecosystem. The various computers in the deployed ecosystem are able to respond to requests from a device directly associated with it in a particular hierarchy, or it may seek a response to the request from a high order logic/data source (parent). The logic/data source parent may then repeat the understanding process to either provide the necessary response to the logic/data source child who then replies to the device or it will again ask a parent logic/data sources for the appropriate response. This architecture allows for a single device to make one request to a single known source and potentially get a response back from the entire ecosystem of distributed servers. |

Domain-based Raft consensus selection of leader nodes in distributed data services
Domain-based server-selection computer-implemented processes and machines implement an extension of RAFT consensus for leader selection based on patterns of update data proximity. Accounts involved in payment or other transactions are maintained as “sharded” data across data store instances that are split into shards according to their temporal activity. If the domain attributes for a node exceed a threshold and are greater than the other nodes, the node is designated as a leader node and the others are designated as follower nodes. This provides an additional optimization in network performance by introducing insights in normal operations within a domain in a distributed network. If the domain attributes do not exceed the threshold and/or are not greater than the other nodes, a traditional consensus algorithm is used to select leader and follower nodes. |

Technologies for high-precision timestamping of packets
Technologies for high-precision timestamping of data packets is disclosed. Several sources of errors that may arise when timestamping the arrival or sending of data packets may be determined and corrected, including variable latencies, semi-static latencies, and fixed latencies.

The phase difference between the edge of the clock on the network interface card and the edge of the clock of the system clock leads to an error in the timestamp value. Determining the phase difference allows for the error in the timestamp value to be corrected. |
