Actively learning PoPs to probe and probing frequency to maximize application experience predictions
Patent number: 11909618Abstract: In one embodiment, a device computes, for each of a set of points of presence (PoPs) via which traffic for an online application can be sent from a location, application experience metrics predicted for the application over time. The device assigns, for each of the set of PoPs, weights to different time periods, based on measures of uncertainty associated with the predicted application experience metrics. The device generates, based on the weights assigned to the different time periods for each of the set of PoPs, schedules for probing network paths connecting the location to the online application via those PoPs. The device causes the network paths to be probed in accordance with their schedules. Results of this probing are used to select a particular PoP from among the set of PoPs via which traffic for the online application should be sent from the location during a certain time period.Type: GrantFiled: April 6, 2022Date of Patent: February 20, 2024Assignee: CISCO TECHNOLOGY, INC.Inventors: Vinay Kumar Kolar, Jean-Philippe Vasseur, Michal Wladyslaw Garcarz -
