Patent number: 7774380Abstract: The present invention discloses a data structure which, given an identifier for a Representational State Transfer (REST) resource, can rapidly yield a configured target and simultaneously yield all configured pattern based rules and constraints for the target. The disclosed data structure is a tree structure including nodes for URL portions. Each node is associated with a hash tree specifically grown in a manner that ensures collision occurrences are non-existent. The tree structure is effectively two or more superimposed trees; one for URL pattern matching to determine a target, another for determining constraints. A single tree traversal, which can be based on a progressive hash, can be used to concurrently determine a target and a set of constraints, which represents improved performance over conventional implementations that require multiple, distinct query/response operations to produce equivalent results.Type: GrantFiled: December 21, 2007Date of Patent: August 10, 2010Assignee: International Business Machines CorporationInventors: Thomas C. Burke, Annapureddy S. Reddy, Aravind Srinivasan

Patent number: 7543069Abstract: Session state affinity is maintained in a workload balancing system that includes a hypertext transfer protocol (HTTP) routing server and a plurality of application servers. The application servers maintain backup session state information for a first session to a first server of the plurality of application servers at fewer than all of the plurality of application servers, detect the unavailability of the first application server at an application server of the plurality of application servers other than the first application and determine a second server that continues the first session. An identification of the second server and the first session is sent from an application server of the plurality of application servers to a HTTP routing server responsive to detecting the unavailability of the first server.Type: GrantFiled: October 18, 2004Date of Patent: June 2, 2009Assignee: International Business Machines CorporationInventors: Srinivas Hasti, Gabriel Garcia Montero, Aravind Srinivasan, Renganathan Sundararaman, Kevin Edward Vaughan

Patent number: 7523171Abstract: A mechanism by which URLs are progressively hashed character by character and clauses of the URL are used to traverse a tree data structure for matching of the URL to resources/rules is provided. The hash code for a single character is appended to a prior hash code for a preceding character in the URL portion. At the time that the entire portion of the URL is hashed, as determined based on the presence of a delimiter character, the particular node in a tree data structure associated with the resulting hash code is identifiable within a hash table of a current node of the tree data structure. Each node in the tree data structure includes a multidimensional hash table for a portion of a URL. The multidimensional hash table is established and grown in a manner that ensures there are no hash collisions.Type: GrantFiled: September 9, 2003Date of Patent: April 21, 2009Assignee: International Business Machines CorporationInventors: Erik John Burckart, Aravind Srinivasan

Patent number: 7427497Abstract: Disclosed herein is a microfluidics device that can be used to prepare natural products and their analogs. The device comprises the enzymes of a biosynthetic pathway immobilized thereon and a means for sequentially directing a starting material and each ensuing reaction product to the enzymes of the biosynthetic pathway in the order corresponding to the steps of the biosynthetic pathway. The device can thus be used to prepare the natural product using the natural starting material of the biosynthetic pathway or analogs of the natural product using an unnatural starting material. Alternatively, artificial pathways can be created by immobilizing an appropriate selection of enzymes on the device in an order whereby each subsequent enzyme can catalyze a reaction with the product of the prior enzyme. Novel chemical entities can be prepared from these artificial pathways.Type: GrantFiled: November 1, 2002Date of Patent: September 23, 2008Assignees: Rensselaer Polytechnic Institute, Darpa, The Regents of the University of CaliforniaInventors: Jonathan S.

Method and Apparatus for Preserving Isolation of Web Applications when Executing Fragmented Requests
Publication number: 20080028086Abstract: A Fragment Aggregator utilizes an application independent surrogate to dispatch fragments and receive responses between isolated web applications. Clients send web application requests to the surrogate, which forwards the request to an isolated web application. When a web application requires other isolated web applications to execute the request, the web application responds to the request with a deferred response. The deferred response includes request fragments for the other isolated web applications. The Fragment Aggregator dispatches the fragments to the other isolated web applications. After receiving responses from the isolated web applications, the Fragment Aggregator combines the response and sends them to the client.Type: ApplicationFiled: July 27, 2006Publication date: January 31, 2008Inventors: Madhu K.
