Method And System For Directing Requests For Content To A Content Server Based On Network Performance

View page
US Patent:
7555542, Jun 30, 2009
Filed:
May 22, 2000
Appl. No.:
09/575839
Inventors:
Matt Ayers - Seattle WA, US
Benjamin J. Black - Seattle WA, US
Chris Brown - Issaquah WA, US
John Carlson - Seattle WA, US
Dan Cohn - Prairie Village KS, US
Scott Laird - Bothell WA, US
Jonathan Miller - Seattle WA, US
Stephen Ramsey - Seattle WA, US
Ophir Ronen - Seattle WA, US
Paul Schachter - Seattle WA, US
Oscar Stiffelman - Seattle WA, US
Assignee:
Internap Network Services Corporation - Atlanta GA
International Classification:
G06F 15/73
US Classification:
709223, 709220
Abstract:
A method and system for pointing a Internet user requesting access to content on a particular web site to one of a plurality of content servers associated with that web site based on one or more cost measurements associated with serving said content. The identification of the web site is mapped to the content servers associated with that web site. The user's IP address is then mapped to a particular content server based on a cost function and the IP address of the selected content server is provided to the user.

Method And Apparatus For Designing Structures

View page
US Patent:
8356000, Jan 15, 2013
Filed:
Apr 13, 2000
Appl. No.:
09/548637
Inventors:
John R. Koza - Los Altos Hills CA, US
Oscar Stiffelman - Seattle WA, US
International Classification:
G06N 3/12
US Classification:
706 13
Abstract:
A method and apparatus for the automatic creation of novel designs, specifically electronic circuits, controllers, antennas, and mechanical systems to satisfy prespecified design goals, using search procedures, such as genetic programming, genetic algorithms, simulated annealing and hill climbing is described. Further, the techniques include automatically creates designs which do not posses key characteristics of preexisting technology. The present invention uses a population of entities which may be evolved to generate structures that may potentially satisfy the design goals. The behavior of the structures is evaluated in view of the design goals, and the structures are compared to a preexisting structure. Those structures more closely meeting the design goals and not similar to the preexisting structure are favored further until a structure is generated that either meets the prespecified design goal or some other process completion criteria. In this manner, a novel structure may be obtained.

Pre-Computed Ranking Using Proximity Terms

US Patent:
20110022591, Jan 27, 2011
Filed:
Jul 26, 2010
Appl. No.:
12/804645
Inventors:
Oscar B. Stiffelman - San Francisco CA, US
William J. Mydlowec - San Francisco CA, US
International Classification:
G06F 17/30
US Classification:
707728, 707E17014, 707E17008
Abstract:
A method for searching the web comprising an off-line phase for generating a numerical score for at least one term within a document retrieved from the web, and an on-line phase comprising accessing the numerical score for the at least one term when the at least one term is used as a search term within a query. The numerical score is used to identify documents to include in a search result.

Method And System For Optimizing Routing Through Multiple Available Internet Route Providers

US Patent:
6981055, Dec 27, 2005
Filed:
Aug 22, 2000
Appl. No.:
09/644221
Inventors:
Abha Ahuja - Seattle WA, US
Matt Ayers - Seattle WA, US
Ben Black - Seattle WA, US
Chris Brown - Issaquah WA, US
Daniel T. Cohn - Prairie Village KS, US
Stephen Ramsey - Seattle WA, US
Ophir Ronen - Seattle WA, US
Paul J. Schachter - Seattle WA, US
Oscar B. Stiffelman - Seattle WA, US
Christopher D. Wheeler - Seattle WA, US
Assignee:
Internap Network Services Corporation - Atlanta GA
International Classification:
G06F015/173
US Classification:
709238, 709239, 370401
Abstract:
A method and system for optimizing routing traffic to a destination when multiple routes are available. A performance monitoring and inference component measures the performance of the available paths to a large set of subnetworks, and uses those measurements to infer the performance of all available paths to an even larger set of subnetworks. A routing optimization component uses a cost function that assigns a cost to a routing table based on information from the performance monitoring and inference component, as well as other path characteristics, and further uses a minimization methodology to find a routing table with a very low cost, as defined by the cost function. A BGP bridge takes the routing table generated by the routing optimization component and communicates that information to the routers using BGP, thereby ensuring that the routers will route traffic in accordance with the routing table.
