Abstract: Systems and methods of the present disclosure provide techniques to locate target devices. An electronic message is sent to a set of landmark devices, signaling each landmark device to transmit echo-request packets to a target device and to other landmark devices and measure network-communication delays. Indications of the network-communication delays are received from the set landmark devices. A first sequence is formed by sorting the set of landmark devices relative to the network-communication delays between the target device and each landmark device. For each respective landmark device, an additional sequence is formed by sorting other landmark devices relative to the network-communication delays between the respective landmark device and the other landmark devices. A sequence-matching operation is applied to the first sequence and the additional sequences to form a ranking of the set of landmark devices relative to the target device.

Abstract: Embodiments of the invention are directed to systems and methods for utilizing a cache to store historical transaction data. A predictive model may be trained to identify particular identifiers associated with historical data that is likely to be utilized on a particular date and/or within a particular time period.

The processing computer may utilize the identifier to retrieve historical transaction data from the cache. The retrieved data may be utilized to perform any suitable operation. By predicting the data that will be needed to perform these operations, and preemptively store such data in a cache, the latency associated with subsequent processing may be reduced and the performance of the system as a whole improved.
