Patent number: 10420167Abstract: Techniques for sharing a cellular network connection amongst multiple devices over a local area network are provided that reduce cellular network load during crowded events. In an aspect, a devices is configure to perform operations that include scanning an area for another device that has established a first wireless cellular connection with a cellular network device of a cellular network and that enables an indirect connection of the device to the cellular network device via a direct connection of the device to the other device via a local network device. The operations further include, in response to identifying the other device as a result of the scanning, sending a request to the other device to connect to the other device via the local network device and to receive the indirect connection to the cellular network device.Type: GrantFiled: January 13, 2017Date of Patent: September 17, 2019Assignees: AT&T INTELLECTUAL PROPERTY I, L.P., BOARD OF TRUSTEES OF MICHIGAN STATE UNIVERSITYInventors: Lusheng Ji, Jeffrey Pang, Jia Wang, Shobha Venkataraman, Muhammad Zubair Shafiq, Xiang-Yang Alex Liu

Patent number: 9270565Abstract: A system for passive estimation of throughput in an electronic network is disclosed. The system may include an plurality of mobile devices configured to operate in the network and may further include an electronic data processor. The processor may be configured to access flow records for data flows associated with the mobile devices during a predetermined time interval. Additionally, the processor may be configured to annotate the flow records with an application field and a content provider field. The processor may also be configured to determine a flow type of each data flow based on the application field and the content provider field of the flow records. Furthermore, the processor may be configured to generate a throughput index that only includes non-rate-limited flow types. Moreover, the processor may be configured to estimate maximum throughput for each data flow having non-rate-limited flow types in the throughput index.Type: GrantFiled: June 11, 2013Date of Patent: February 23, 2016Assignee: AT&T INTELLECTUAL PROPERTY I, L.P.Inventors: Jeffrey Pang, Karen Schoonover, Dinesh Chachidhanandam, Alexandre Gerber, Michael Salmon, Oliver Spatscheck, Shobha Venkataraman

Patent number: 8671183Abstract: A system for visualization of performance measurements is disclosed. The system may include an electronic data processor configured to receive a stream of the performance measurements and select a maximum number of leaf nodes of a plurality of nodes for use in an adaptive decision tree. Additionally, the electronic processor may be configured to determine a depth of each branch in the adaptive decision tree needed to differentiate performance among internet protocol addresses in an internet protocol prefix of each node. Each of the plurality of nodes may be annotated with a predicted latency category and the processor may be configured to generate the adaptive decision tree based on the maximum number of leaf nodes selected, the depth of each branch determined, the predicted latency category, and on the stream of performance measurements associated with the network. Moreover, the processor may display the adaptive decision tree.Type: GrantFiled: December 14, 2010Date of Patent: March 11, 2014Assignee: AT&T Intellectual Property I, L.P.Inventors: Shobha Venkataraman, Jeffrey Pang, Subhabrata Sen, Oliver Spatscheck

Publication number: 20090113016Abstract: Disclosed are email server management methods and systems that protect the ability of the infrastructure of the email server to process legitimate emails in the presence of large spam volumes. During a period of server overload, priority classes of emails are identified, and emails are processed according to priority. In a typical embodiment, the server sends emails sequentially in a queue, and the queue has a limited capacity. When the server nears or reaches that capacity, the emails in the queue are analyzed to identify priority emails, and the priority emails are moved to the head of the queue.Type: ApplicationFiled: October 24, 2007Publication date: April 30, 2009Inventors: Subhabrata Sen, Patrick Haffner, Oliver Spatscheck, Shobha Venkataraman
