Publication number: 20250148664Abstract: A method for identifying relationships between nodes in a graph is provided. The method comprises determining a count of relationships for each relationship type associated with each node in a pair of nodes on the graph. The relationship types are represented by edges connected to the nodes in the pair of nodes. A number of common relationships are determined between the pair of nodes for each relationship type. A count for each common relationship is determined for the number of common relationships between the pair of nodes. A similarity coefficient for each common relationship is determined based on the count for each common relationship and the count of relationships for each relationship type associated with each node in the pair of nodes. A weighted score is generated to represent strength for relationships between the pair of nodes using the similarity coefficients.Type: ApplicationFiled: November 3, 2023Publication date: May 8, 2025Inventors: Abhishek Chaudhary, Harpreet Kaur, Shankar Krishnamurthy, Swamy Kocherlakota

Patent number: 10798530Abstract: Schemes, methods and examples for optimization of broadcast and multicast frame delivery when at least one client device in a basic service set (BSS) is in a power-save mode are described. A communication apparatus associated with a BSS receives a broadcast or multicast frame after a first Delivery Traffic Indication Map (DTIM). The communication apparatus transmits the broadcast or multicast frame to at least a first client device in the BSS, without buffering the broadcast or multicast frame for transmission following a second DTIM which is subsequent the first DTIM, while at least a second client device in the BSS is in a power-save mode.Type: GrantFiled: December 11, 2017Date of Patent: October 6, 2020Assignee: MEDIATEK SINGAPORE PTE.

Patent number: 10756951Abstract: Techniques for use in network incident identification are described. In response to an occurrence of an unknown network incident, a plurality of log messages (e.g. syslog messages) are received from a plurality of network components in one or more networks. In one illustrative example, a plurality of relationships between interfaces and events are derived from the received log messages and characterized as a plurality of graphical component relationships. One or more groups of connected components are determined from the graphical component relationships and network component connection data which indicate interface relationships of the network components. Here, groups of connected components may be logically joined based on the network component connection data indicating one or more interface relationships.Type: GrantFiled: July 27, 2017Date of Patent: August 25, 2020Assignee: Cisco Technology, Inc.Inventors: Parthibhan Paramaguru, Prashant Anand, Vasudevan Visvanathan, Sundar Ramakrishnan, Dharmarajan Subramanian, Rohit Kumar Gupta, Abhishek Chaudhary

Patent number: 8958701Abstract: A method, a network, and a node each implement the transmission of Automatic Protection Switching (APS) switching coordination bytes across an OTN network. A working signal and a protection signal are received, one of which is designated as an active signal. The active signal is encapsulated in an Optical channel Data Unit (ODU) signal. APS switching coordination bytes from the working and protection signals are placed in an overhead segment of the ODU signal. The ODU signal is transmitted into and received from an Optical Transport Network (OTN) network. The working and protection signals are recreated based on the active signal encapsulated in the ODU signal and the APS switching coordination bytes in the overhead segment. The recreated working and protection signals are transmitted. In this manner, a single ODU signal may be used to transmit both the working and protection signals.Type: GrantFiled: December 27, 2012Date of Patent: February 17, 2015Assignee: Ciena CorporationInventors: Abhishek Chaudhary, Hongxing Meng, Satish Gopalakrishna

Patent number: 8953948Abstract: The present disclosure provides to Optical Transport Network (OTN_ synchronization systems and methods that maintain proper sequential ordering of events at nodes which may be utilized in performing root cause analysis or diagnosing network performance. In an exemplary embodiment, the systems and methods utilize functionality incorporated into OTN providing a cost effective and standards-based approach to nodal synchronization. Once synchronized, network events are logged with an appropriate timestamp enabling a determination of a sequential order of network events can be determined. Further, the node timestamps may be synchronized, with microsecond or even sub-microsecond of precession which is critical in diagnosing network failures or slow traffic recovery.Type: GrantFiled: November 22, 2011Date of Patent: February 10, 2015Assignee: Ciena CorporationInventors: Hongxing Meng, Abhishek Chaudhary, Gustav Karl Larsson, Saravanan Purushothaman

Patent number: 8458541Abstract: Scan chains are used to detect faults in integrated circuits but with the size of today's circuits, it is difficult to detect and locate scan chain faults, especially when the scan data in and scan data out have been compressed. A method for debugging scan chains includes selecting a scan chain for debugging using a scan chain selection block and then providing scan test vectors to the selected scan chain. The scan test vectors undergo various scan test stages to generate scan response vectors. The scan response vectors are compared with ideal response vectors to identify a failing scan chain.Type: GrantFiled: March 25, 2011Date of Patent: June 4, 2013Assignee: Freescale Semiconductor, Inc.Inventors: Sandeep Jain, Nikila Krishnamoorthy, Abhishek Chaudhary, Nipun Mahajan, Saurabh Chauhan
