Publication number: 20230300025Abstract: Techniques are provided for facilitating network devices to obtain configuration updates from a central configuration repository. Configuration update information is received regarding a configuration update in a configuration repository. A data tree is updated based on the configuration update information. An identifier unique to the update is generated. A determination is performed that network device properties of a network device correspond to a set of network device properties indicated for the configuration update information. A notification indicating the availability of the configuration update is sent over one or more networks to the network device.Type: ApplicationFiled: May 25, 2023Publication date: September 21, 2023Inventors: Michael Gibbings Fink, Justin Costa-Roberts, Avinash Siva Kumar

Patent number: 11709802Abstract: A cluster data replication system includes a plurality of network elements and controllers. The controllers form a cluster that is able to elect one of the controllers as a master controller with the others being follower controllers. The elected controller updates, responsive to being elected the master controller, state information in a system database of the elected controller to indicate that the elected one of the controllers is the master controller. The master controller includes one or more objects that are enabled in reaction to the state information, and which coordinate replication of changes to the data, system database, and state information from the master to the follower controllers. Each follower controller includes one or more objects able to, in reaction to the state information, disable initiation of the replication of changes to the data, system database and state information by the one or more objects in each follower controller.Type: GrantFiled: October 5, 2021Date of Patent: July 25, 2023Assignee: ARISTA NETWORKS, INC.Inventors: Gagandeep Arneja, Justin Costa-Roberts, Andre Pech, Hua Zhong, Arturo Escaip

Patent number: 11169969Abstract: A cluster file replication system is provided. Each controller of the plurality of controllers is configured to access a filesystem having a plurality of files including a system database of a controller having state information of the plurality of controllers. Each controller is further configured to have one or more service agents. The one or more service agents of each controller is configured to respond to one of the plurality of controllers becoming a master controller of the cluster. The one or more service agents of each controller is configured to set up one or more objects that react to the state information and coordinate replication of changes to the files, system database and state information from the master controller to follower controllers in the cluster. The one or more objects on each of the follower controllers is supportive of the follower controllers receiving the changes but disabled from initiating the replication. A method for cluster file replication is also provided.Type: GrantFiled: March 2, 2020Date of Patent: November 9, 2021Assignee: Arista Networks, Inc.Inventors: Gagandeep Arneja, Justin Costa-Roberts, Andre Pech, Hua Zhong, Arturo Escaip

Patent number: 10992562Abstract: A method includes receiving a single request to configure a continuous route tracer (CRT) between a first plurality of network devices and a second plurality of network devices and configuring, by a processing device of a control server, the CRT between the first plurality of network devices and the second plurality of network devices. The method further includes receiving a plurality of probe reports corresponding to a plurality of CRT probes sent between the first plurality of network devices and the second plurality of network devices and analyzing the reports to detect one or more anomalies corresponding to a network comprising the first plurality of network devices and the second plurality of network devices. The method further includes providing the one or more anomalies for display.Type: GrantFiled: December 29, 2017Date of Patent: April 27, 2021Assignee: Arista Networks, Inc.Inventors: Gagandeep S. Arneja, Justin Costa-Roberts, Charanjith Kunduru

Patent number: 10346270Abstract: A method for high-availability operation is provided. The method includes communicating state information from each of a plurality of network elements to at least a first master network controller. The method includes communicating transformed state information from the first master network controller to the plurality of network elements and to each of a plurality of follower network controllers. The method includes continuing the high-availability operation with a new master network controller selected from among the plurality of follower network controllers as a failover, using the transformed state information in the new master network controller and in the plurality of network elements, responsive to a failure of the first master network controller. A network controller system is also provided.Type: GrantFiled: May 25, 2016Date of Patent: July 9, 2019Assignee: ARISTA NETWORKS, INC.Inventors: Justin Costa-Roberts, Karthik Subraveti, Thejesh Panchappa, Gagandeep Arneja, Andre Pech
