Publication number: 20240098615Abstract: This disclosure provides systems and methods for use of automated frequency coordination (AFC) to manage transmission power and frequencies. In some implementations, a device transmits, to a network entity, an AFC request. The device receives, from the network entity, an AFC response, the AFC response including an AFC power level indication of one or more nearest neighboring entities. The device sets a transmit power of the device based at least in part on the AFC power level indication of at least one of the one or more nearest neighboring entities, and the device transmits at the transmit power. In some instances, the device transmits a first number of AFC requests during a first instance of travelling along a path and transmits a second number of AFC requests less than the first number of AFC requests during one or more successive instances after the first instance of travelling along the path.Type: ApplicationFiled: September 15, 2022Publication date: March 21, 2024Inventors: Subramanian ANANTHARAMAN, Sreekanth NATARAJAN, Sandip HOMCHAUDHURI, Sujatha VARADARAJAN

Publication number: 20240056224Abstract: Exemplary methods, apparatuses, and systems include duplicating a packet within a plurality of packets to be transmitted to a destination computing node as a sequence of packets. The plurality of packets including the duplicate of the packet are transmitted to the destination computing node. Upon receiving a first acknowledgement of the packet from the destination computing node, it is determined that the first acknowledgment is directed to a duplicated packet. In response to determining that the first acknowledgment is directed to a duplicated packet, it is determined that a second acknowledgement has yet to be received for each of one or more packets within the plurality of packets transmitted prior to the packet. In response to determining that the second acknowledgement has yet to be received, the one or more packets are retransmitted to the destination computing node.Type: ApplicationFiled: February 14, 2023Publication date: February 15, 2024Inventors: Subramanian Varadarajan, Rosarin Roy Antonyraj, Kumaravel Senthivel

Publication number: 20230273990Abstract: Techniques for code modification for detecting abnormal activity are described. Web code is obtained. Modified web code is generated by changing a particular programmatic element to a modified programmatic element throughout the web code. Instrumentation code is generated configured to monitor and report on one or more interactions with versions of the particular programmatic element. The instrumentation code is caused to be provided in association with the modified web code to the first client device in response to the first request from the first client device. Report data generated by the instrumentation code is received. The report data describes abnormal activity at the first client device, the abnormal activity comprising an interaction with a version of the particular programmatic element that does not exist in the modified web code. Based on the report, it is determined that the first client device is likely controlled by malware.Type: ApplicationFiled: February 25, 2022Publication date: August 31, 2023Applicant: Shape Security, Inc.Inventors: Justin D.

Patent number: 11483231Abstract: Exemplary methods, apparatuses, and systems include a path management hub and proxy server nodes that form a mesh network. The hub receives link performance metrics from each of the nodes. The hub determines optimal paths between first and second nodes for each of a plurality of metric types or a combination of metric types using the received link performance metrics. The hub maps a service identifier to a plurality of the determined optimal paths for a context representing one or more link performance metric types. The hub transmits a next hop for each of the plurality of mapped optimal paths along with the mapping to the first node. The first node receives the service identifier mapped to the next hops and traffic for the first connection. In response to determining the received traffic is for the service, the first node selects a first next hop and forwards the traffic.Type: GrantFiled: August 25, 2020Date of Patent: October 25, 2022Assignee: ZYCADA NETWORKS, INC.Inventors: Rosarin Roy Antonyraj, Subramanian Varadarajan
