Abstract: In one embodiment, a device obtains path probing data for paths between a set of network nodes wherein a first subset of the set of network nodes are operated by a provider of an online application or service and a second subset of the set of network nodes operated by affiliates. The device generates, based on the path probing data, a performance model of path performances between clients in different geolocations and the online application or service via each of the set of network nodes. The device determines, based on the performance model, a particular node in the second subset should be used as a point of presence for clients located in a particular one of the different geolocations to access the online application or service. The device configures a network overlay including the first subset and the particular node as points of presence for the online application or service.

Abstract: A mobile device is provided that includes biometric sensor(s), and a processor that causes the biometric sensor(s) to acquire a physiological marker of a user, and identify and authenticate the user. The processor sends a message to an authentication server that indicates the user is authenticated, and receives a response from the authentication server that includes a unique authentication code. The processor receives selection of a thereby selected over-the-counter (OTC) drug, and communicates with a point-of-sale (POS) system with contactless payment capability. The processor sends a purchase message to the POS system that includes the unique authentication code, an identifier of the selected OTC drug, and payment information. And the POS system communicates with the authentication server to validate the unique authentication code, and with an authorization server to authorize payment for the selected OTC drug based on the payment information.
