Publication number: 20160212116Abstract: Authentication of devices to receive services provided by service providers over communications networks such as open access networks, wherein the provider of the network need not have access to secret information shared between the devices and the service providers. A request is received from a device to receive services from a service provider and is forwarded to the service provider. A challenge and an expected response is received from the service provider and the challenge is forwarded to the device. A response to the challenge is received from the device the device is authenticated to receive services from the service provider if the response received from the device matches the expected response provided by the service provider.Type: ApplicationFiled: January 18, 2016Publication date: July 21, 2016Inventors: Christopher D.

Patent number: 8943193Abstract: A service model, integrated system, and method for enabling a service provider to deliver an integrated web hosting and content distribution service offering, which affords assured operational performance service levels, regardless of whether the customer's web site is served by the service provider's hosting center, the service provider's content distribution network (CDN), by a third party web host, or by a third party CDN. A monitoring system of the primary service provider receives detailed capacity and health statistics from any CDN under the operational control of the primary service provider, receives aggregate capacity and health statistics from other CDNs not under the operational control of the primary service provider. A redirection system then decides to which web host, content distribution network, or combination thereof, user requests for content are directed in order that operational performance service levels are maintained.Type: GrantFiled: April 4, 2012Date of Patent: January 27, 2015Assignee: Marlow Technologies, LLC.Inventors: Frederick Douglis, David H.

Patent number: 8855147Abstract: A method includes receiving, at a transmit site, a first stream of packets addressed to an end user device in a first address space. The first stream of packets is encapsulated to form a second stream of packets addressed in a second address space. A first packet of the second stream of packets is assigned to a first radio frequency channel of a plurality of radio frequency channels. A second packet of the second stream of packets is assigned to a second radio frequency channel of the plurality of radio frequency channels. The first packet is transmitted via the first radio frequency channel and, in parallel, the second packet is transmitted via the second radio frequency channel.Type: GrantFiled: July 6, 2011Date of Patent: October 7, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: Bhavesh N.

Patent number: 8813213Abstract: An application provisioning device may be used to manage a profile of a host and provide data corresponding to a selected application for installation at a host. A reverse firewall may use the profile of the host to determine whether to allow or block particular network communication from an application running on the host. An indication of a selected application may be received at the application provisioning device. Configuration information may also be received at the application provisioning device. The application provisioning server may request an update to the profile of a host and transmit such a request. The profile may be updated to reflect the configuration information and/or information of the selected application. Data corresponding to the selected application may be updated and transmitted to a host computer, where it may be installed. Therefore, the installed application running on the host may operate without being prematurely blocked by the reverse firewall.Type: GrantFiled: May 24, 2013Date of Patent: August 19, 2014Assignee: AT&T Intellectual Property II, L.P.Inventors: William A. Aiello, Charles Robert Kalmanek, Jr., William J. Leighton, III, Patrick McDaniel, Subhabrata Sen, Oliver Spatscheck, Jacobus E. Van Der Merwe
