Patent number: 10623503Abstract: A monitoring system monitors traffic flows that are exchanged over a communication network. The system characterizes the flows in terms of their temporal traffic features, and uses this characterization to identify communication devices that participate in the same communication session. By identifying the communication devices that serve as endpoints in the same session, the system establishes correlations between the users of these communication devices. The monitoring system characterizes the flows using traffic features such as flow start time, flow end time, inter-burst time and burst size, and/or statistical properties of such features. The system typically generates compressed-form representations (“signatures”) for the traffic flows based on the temporal traffic features, and finds matching flows by finding similarities between signatures.Type: GrantFiled: October 19, 2018Date of Patent: April 14, 2020Assignee: VERINT SYSTEMS LTD.Inventor: Haim Zlatokrilov

Patent number: 10382319Abstract: Embodiments are directed to facilitate multiple tunnels to be reachable via inter-chassis ling from virtual link trunking (VLT) peers and also to avoid traffic tromboning with an optimal path to all next hops. During initialization, a default egress object is created through an ICL with the next hop defined as VLT peer2 by setting the MAC address to be the MAC address of the VLT peer2, and the VLAN to be any one of the L3 spanned VLANs. When any of the VXLAN tunnels are resolved through ICL LAG, the process uses the default egress object created on ICL. Using the default egress object created on ICL, any traffic from VLT peer1 intended to go through ICL is terminated on VLT peer2 and will get routed again to their respective next hops. This creates a single egress object to the VLT peer and allowing multiple VXLAN tunnels to be reachable through ICL with optimal path towards all next hops.Type: GrantFiled: October 30, 2017Date of Patent: August 13, 2019Assignee: Dell Products LPInventors: Avinash Natarajan, Damodharan Screenivasaga Perumal, Ramasubramani Mahadevan, Nirupa Venkatapathy, Venkata Gouri Rajesh E

Patent number: 10225750Abstract: A module transmits send information to be processed by an information processing apparatus along a transmission path on which the information processing apparatus is present. When the send information is sent in accordance with predetermined sending parameters, if a sending failure in which a sending completion state of the send information cannot be confirmed occurs, a part or all of the sending parameters used for sending of the send information with respect to which the sending failure has occurred are changed, and the send information is resent in accordance with the sending parameters after the changing. Then, the predetermined sending parameter changed between the occurrence of the sending failure and confirmation of the sending completion state of the resent send information, and resend result information related to a send result corresponding to the changed predetermined sending parameter are acquired and sent toward a predetermined processing apparatus.Type: GrantFiled: March 14, 2014Date of Patent: March 5, 2019Assignee: OMRON CorporationInventors: Ryota Yamada, Yusuke Yamaji, Yuki Inoue, Hajime Umeki

Patent number: 10223247Abstract: Generating pseudorandom test items for software testing of an Application Under Test (AUT) is provided. In one example, a method comprises selecting an oracle of one or more oracles within a test provider directory structure, the oracle defining one or more logical paths each comprising one or more test conditions and an expected result. A pseudorandom test item having an initial state of empty is generated, and a logical path of the one or more logical paths is selected. The one or more test conditions of the logical path are translated into a constraint. Based on the constraint, a pseudorandom test input is generated and stored in the pseudorandom test item in association with the expected result corresponding to the logical path.Type: GrantFiled: July 5, 2016Date of Patent: March 5, 2019Assignee: Red Hat, Inc.Inventors: Hao Liu, Min Zhan, Luyao Huang

Patent number: 10193746Abstract: A first maintenance endpoint (MEP) device may identify that a first interface of the first MEP device is associated with a connectivity failure. The first MEP device may provide, to a second MEP device, a first continuity check message (CCM), that includes a MEP identifier of the first MEP device. The first CCM may cause the second MEP device to designate a second interface of the second MEP device as being offline. The first MEP device may receive, from the second MEP device, a second CCM, that includes the MEP identifier of the first MEP device and information indicating that the second interface of the second MEP device is offline. The first MEP device may execute a rule to avoid a deadlock situation based on the second CCM including the MEP identifier of the first MEP device.Type: GrantFiled: December 21, 2016Date of Patent: January 29, 2019Assignee: Juniper Networks, Inc.Inventors: Vamsi Krishna A, Sudheendra Bellamkonda, Paleti Venkata Ramana, Prabhu Raj V.

Patent number: 10164873Abstract: Systems and methods utilize an all-or-none switchover to prevent split-brain problems in a Multi-Chassis Link Aggregation Group (MC-LAG) network. A standby node in the MC-LAG network can perform the steps of remaining in a standby state responsive to a loss of adjacency with an active node, wherein, in the standby state, all standby links between the standby node and a common endpoint are non-distributing; monitoring frames transmitted by the common endpoint to the standby node over the standby links; and determining based on the monitoring frames whether all active links between the active node and the common endpoint have failed and entering an active state with all the standby links distributing based thereon.Type: GrantFiled: June 1, 2017Date of Patent: December 25, 2018Assignee: Ciena CorporationInventors: Ankit Sood, Hossein Baheri, Leela Sankar Gudimetla, Vijay Mohan Chandra Mohan, Wei-Chiuan Chen

Patent number: 10142224Abstract: A path computation method and a related device are disclosed. The method includes: a second network device receives path requirement information and a recomputation condition that are sent by a first network device; the second network device first obtains by means of computation a path meeting a requirement according to the path requirement information, and sends description information of the path meeting the requirement to the first network device; then the second network device constantly determines whether the recomputation condition is met; and when the recomputation condition is met, the second network device performs path recomputation, and sends description information of a path obtained by means of recomputation to the first network device. Therefore sensitivity for triggering path recomputation can be improved and a quantity of communication messages between network devices can be reduced.Type: GrantFiled: November 8, 2016Date of Patent: November 27, 2018Assignee: Huawei Technologies Co., Ltd.Inventors: Hong Zhou, Qin Wu, Feng Li, Yue Yin

Patent number: 10142426Abstract: A monitoring system monitors traffic flows that are exchanged over a communication network. The system characterizes the flows in terms of their temporal traffic features, and uses this characterization to identify communication devices that participate in the same communication session. By identifying the communication devices that serve as endpoints in the same session, the system establishes correlations between the users of these communication devices. The monitoring system characterizes the flows using traffic features such as flow start time, flow end time, inter-burst time and burst size, and/or statistical properties of such features. The system typically generates compressed-form representations (“signatures”) for the traffic flows based on the temporal traffic features, and finds matching flows by finding similarities between signatures.Type: GrantFiled: March 29, 2016Date of Patent: November 27, 2018Assignee: VERINT SYSTEMS LTD.Inventor: Haim Zlatokrilov
