Loon Network Data

<strong>Loon sought to provide data connectivity to under-served regions via 4G LTE cell service hosted on free-floating, high-altitude balloons. To backhaul data, the balloons used point-to-point radio links to connect with each other and to transceivers connected to the network core on the ground (aka. "ground stations"). These links were selected &amp; commanded by a centralized Temporo-Spatial Software Defined Network (TS-SDN) controller running on the ground. More details about the system architecture and operation can be found in the Loon Library or in "SDN in the Stratosphere: Loon's Aerospace Mesh Network" from the proceedings of SIGCOMM 2022.</strong> <strong>The dataset provided here consists of internal state from the TS-SDN and network telemetry gathered from serving commercial traffic and R&amp;D experiments. Loon’s networking use case is unique in several ways:</strong> <strong>Balloons and their base stations/eNodeBs were located in the stratosphere and changed position as they were pushed by the wind.</strong> <strong>The network was comprised of a combination of LTE, WiFi, E-band, Wired technologies</strong> <strong>The topology of our E-band backhaul meshes spanned thousands of kilometers and changed frequently.</strong> <strong>eNodeBs entered and exited the cellular network depending on their position and the availability of power and backhaul connectivity.</strong> <strong>Loon collected data using system telemetry from Loon assets (balloons, ground stations, etc) in the field. These logs were extracted from various storage systems and processed for external publication. </strong>
