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: 11552870Abstract: Systems and methods for automatically configuring network elements for in-band telemetry are disclosed. A controller of a configuration engine, which includes a flow analyzer and an INT configuration module, receives sampled packets and flow updates from network elements that are not yet configured for INT telemetry. The controller forwards the packets to the flow analyzer that extracts flow properties from the received packets, generates a flow summary along various metrics, and records it in a multi-dimensional matrix. A few metrics from top flows are selected and forwarded to the INT configuration module to identify network elements from whom packets containing the selected metrics were received. The identified network elements are automatically configured with the selected INT configuration such that INT telemetry data can be collected from them. Changes to the flow are dynamically accommodated by reconfiguring the network elements based on the telemetry data received after they have been configured.Type: GrantFiled: December 22, 2020Date of Patent: January 10, 2023Assignee: ARISTA NETWORKS, INC.Inventor: Gagandeep Arneja

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: 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
