Patent number: 11736915Abstract: The subject disclosure relates to ways to ensure vehicle network connectivity. In some aspects, a process of the technology includes steps for receiving local network measurement data including one or more connectivity metrics for at least one network provider (e.g., an ISP), and updating a geo-connectivity database using the received local network measurement data. In some aspects, the process can include additional steps for transmitting a geo-connectivity request to a remote Intelligent Vehicle Connectivity Analytics (IVCA) gateway, and for receiving a geo-connectivity reply from the remote IVCA gateway, the geo-connectivity reply including information regarding network availability for the at least one network provider along a vehicle path. Systems and machine-readable media are also provided.Type: GrantFiled: July 1, 2022Date of Patent: August 22, 2023Assignee: Aspen Networks, Inc.Inventors: Sajit Bhaskaran, John Tong-Kin Yu

Patent number: 10230570Abstract: A Multi-Homing System is equipped with an Adaptive JSP Access Cloud State Detection apparatus (ACSD) that improves the reliability of the availability of digital connections (links) between computer sites, such as a Computer Premises Network and the Internet, in which such connections are made by connecting through a multiplicity of ISP Access Clouds (links). Reliability is improved over prior art methods by using data elements of Internet Protocol datagrams, e.g. record fields or bits of fields, that are regularly and normally exchanged between the ISP Access Clouds and the CPN without creating additional data traffic. Data Elements from each ISP Access Cloud are used by processing functions of the by the ACSD to test for conditions that indicate that it may be in a DOWN status.Type: GrantFiled: November 18, 2016Date of Patent: March 12, 2019Assignee: Aspen Networks, Inc.Inventors: Sajit Bhaskaran, Anmol Kumar, Prashanth Krishnamurthy

Patent number: 8059644Abstract: An apparatus and a method are described for zero packet loss task migration in an network switch in a computer network. The invention relates to active or programmable networks, i.e. networks based on packet switching algorithms and switch configurations which are subject to change. A well-defined protocol enables an intelligent switch to migrate tasks from one forwarding engine to another without any packet loss. This enables the algorithms and configurations of the switch to be updated or modified arbitrarily.Type: GrantFiled: October 16, 2009Date of Patent: November 15, 2011Assignee: Aspen Networks, Inc.Inventor: Sajit Bhaskaran

Patent number: 8009554Abstract: A method for achieving multiple link quality of service for video and voice calls over Internet links, or over IP links running in private networks, is described. This method applies to both the non-mobile domain (alternate paths exist in one place at the same time) as well as the mobile domain (one path is used at any one place at a given time, but the user device roams from place to place). This method can be implemented as either computer software or other digital logic (ASIC or FPGA). Using this invention, voice and video calls can be moved at will from one path to another, as many times as required during a single conversation, without breaking the RTP voice or video payload stream. The benefit is that embodiments of this invention have a significantly higher probability that a call never breaks under various conditions of quality degrade. This includes the case of link and router failures, which are treated as a special case of quality degrade in the context of voice and video.Type: GrantFiled: June 11, 2008Date of Patent: August 30, 2011Assignee: Aspen Networks, Inc.Inventors: Bill Chin, Sajit Bhaskaran, Robin Mavunkel
