Patent number: 10594581Abstract: A system includes first and second cache servers, a domain name server, and a route controller. The cache servers respond to an anycast address. The first and second cache servers respond to first and second unicast addresses respectively. The router controller determines if the first cache server is non-overloaded, overloaded, or offline. The route controller instructs the domain name server to provide the second unicast address when the status is overloaded or offline, and modifies routing of the anycast address to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server receives a request from a requestor, and provides an anycast address to the requestor when the status of the first cache server is non-overloaded, and provides the second unicast address to the requestor when the status of the first cache server is offline or overloaded.Type: GrantFiled: July 23, 2018Date of Patent: March 17, 2020Assignee: AT&T Intellectual Property I, L.P.Inventors: Mario A. Santoro, Herani Brotman, Alan L. Glasser, James Miros, Oliver Spatscheck, Jacobus E. Van der Merwe

Publication number: 20170304711Abstract: A variation of the casino game of blackjack which is played between players and without dealing a dealer's hand. Each player places an ante wager into a pot. Two cards are dealt to each player and the player with a hand closest to 21 without going over 21 wins the pot, minus any commission taken by the house. In another variation, a side wager can be offered on a standard game of blackjack (which uses a dealer's hand) which pays based on how many cards of a particular rank (e.g., ace) are present in a combined hand comprising both the player's and the dealer's hand.Type: ApplicationFiled: March 1, 2017Publication date: October 26, 2017Inventor: Mario Santoro

Patent number: 9667516Abstract: A system including first and second servers, a domain server, and a route controller is disclosed. The first and second servers are configured to respond to an anycast address and to first and second unicast addresses respectively. The route controller is configured to determine whether the first cache server is non-overloaded, overloaded, or offline, and may instruct the domain name server to provide to provide the second unicast address when the status is overloaded or offline. Routing of the anycast address may be modified so as to direct a content request sent to the anycast address to the second cache server when the status is offline. The domain name server may receive a request for a cache server address and provide the anycast address to the requestor when the status is non-overloaded, and provide the second unicast address when the status is offline or overloaded.Type: GrantFiled: October 2, 2015Date of Patent: May 30, 2017Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Mario A.

Patent number: 5416862Abstract: The capacity of a multi-mode optical fiber system, such as a local area network, is increased by selectively propagating only higher-order modes through the multi-mode fiber. Because only a small number of higher-order modes are propagated, pulse spreading induced by modal dispersion is minimized, and the bandwidth of the multi-mode fiber is increased. Because of the reduced modal dispersion, higher-order modes are recovered from the multi-mode fiber in accordance with the invention without filtering the output of the fiber. This renders the system less vulnerable to mechanical perturbations that are known to reduce the bit error rate of systems requiring filtering. Thus, by propagating only higher-order modes in this manner, the "bandwidth-distance" product of the multi-mode fiber is significantly increased.Type: GrantFiled: April 7, 1993Date of Patent: May 16, 1995Assignee: AT&T Corp.Inventors: Zygmunt Haas, Mario A.

Patent number: 5311346Abstract: The polarization-dependent distortion of an optical signal transmitted through an optical fiber is reduced by aligning the polarization of the optical signal to minimize the received signal distortion. A polarization controller (a device which can change the polarization of light in an optical fiber) may be located at either the input or output end of a long haul optical fiber system and is used to align the polarization of the signal to minimize the received signal distortion. Automatic operation of the polarization controller can be obtained by using a steepest-descent method based on a distortion measure of the received signal for the optical signal transmitted through the optical fiber to generate control signals which are used to control the polarization controller.Type: GrantFiled: June 17, 1992Date of Patent: May 10, 1994Assignee: AT&T Bell LaboratoriesInventors: Zygmunt Haas, Craig D. Poole, Mario A. Santoro, Jack H. Winters

Patent number: 5175640Abstract: A plurality of M receivers are utilized to receive a plurality of N channels from various incoming multiplexed data signals, N.gtoreq.M, where each incoming data signal arrives on a separate wavelength and comprises several channels. Each of the M receivers, in sequence, receives a separate one of the N channels, thereby M of the N channels. The process then repeats for the next M channels, in the same sequence as the first M channels. The repetitions continue until all N channels are received.Type: GrantFiled: April 25, 1990Date of Patent: December 29, 1992Assignee: AT&T Bell LaboratoriesInventors: Kai Y. Eng, Richard D. Gitlin, Mario A. Santoro

Patent number: 5093743Abstract: An interconnect fabric is constructed from a plurality of fixed wavelength transmitters which are used to transmit arriving data packets through a star coupler, and a plurality of tunable receivers which tune to whatever frequency necessary to receive the desired data from the star coupler. A control network, constructed from a plurality of fixed wavelength receivers and a plurality of tunable transmitters, determines what frequencies the tunable receivers should tune to, and sends a signal to effectuate such tuning.Type: GrantFiled: December 28, 1990Date of Patent: March 3, 1992Assignee: AT&T Bell LaboratoriesInventors: Kai Y. Eng, Mark J. Karol, Mario A. Santoro
