Abstract:

A device can be configured to receive a transmission control protocol (TCP) packet from a user device and determine, based on data included in a header portion of the TCP packet, that the TCP packet includes a toll-free token.

International Classification:

H04L 12/14
H04L 29/08
H04L 29/06
G06Q 30/02

Abstract:

A device may receive network traffic. The device may determine that the network traffic includes a hypertext transfer protocol (HTTP) message. The device may determine, based on the HTTP message, that the network traffic is associated with a toll-free data service. The toll-free data service may cause a first party to be billed for data usage associated with the network traffic by a second party. The device may perform validation operations, based on validation information included in the HTTP message, to determine whether to provide the network traffic or drop the network traffic. The network traffic may be provided when the validation operations are successful, and may be dropped when the validation operations are unsuccessful. The device may cause the first party or the second party to be billed for the data usage based on the network traffic being associated with the toll-free data service.

International Classification:

H04L 29/06

Abstract:

A device may determine a resource identifier for accessing a segment of streaming media content. The device may determine that a signature associated with the resource identifier is not stored in memory. The signature may be generated based on a character string of the resource identifier. The device may request validation of the resource identifier based on determining that the signature is not in memory. The device may receive the signature associated with the resource identifier based on requesting validation. The device may store the signature based on receiving the signature. The device may request the segment of streaming media content using the resource identifier and the signature, stored in memory, to receive toll-free access to the segment of streaming media content.
