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: 11632288Abstract: In some implementations, a method is provided. The method includes determining a physical topology of a network and monitoring network events based, at least in part, on control plane information received from one or more devices in the network. The method also includes monitoring the performance of each of a plurality of applications running on the network based, at least in part, on a set of application calls initiated by each application. When a drop in performance of an application is detected, the drop in performance is correlated with one or more of a plurality of detected network events to determine a cause of the drop in performance.Type: GrantFiled: June 22, 2022Date of Patent: April 18, 2023Assignee: ARISTA NETWORKS, INC.Inventors: Fred Hsu, Andre Pech

Patent number: 11632438Abstract: A method for distributing network services for a network device through a multi-tenant network service. An identification parameter is associated with the device and is stored in a database by an orders management system after the device is ordered. The method includes establishing a network connection between a network device and a multi-tenant network service and, in response to establishing the network connection, obtaining device-associated identification parameter from the network device. The identification parameter is used to query the database for at least one record associated with the network device identifying a tenant of the multi-tenant network service in which the tenant corresponds to the device. The service maps the network device to the identified tenant of the multi-tenant network service and distributes network services based upon the mapping of the network device to the identified tenant.Type: GrantFiled: October 14, 2021Date of Patent: April 18, 2023Assignee: ARISTA NETWORKS, INC.Inventors: Ethan Rahn, Andre Pech, Aaron Delaney, Roy Magruder

Patent number: 11470075Abstract: Network devices are securely provisioned through authenticated ZTP servers. In some approaches, a storage device local to the network device includes information for connecting with and authenticating a local or remote ZTP server. This information may include a root of trust to use when connecting with a designated ZTP server. The ZTP server may be identified using either a dynamic host configuration protocol (DHCP) server or a network address specified in the local memory storage. In an approach, the local memory storage is a removable USB flash memory device inserted into the network device when the device is booted up. In another approach, the ZTP authentication information is stored within memory integrated within the network device. Once a ZTP server is connected to the network device, a secure connection may be established such as a secure transport layer session (TLS) utilizing the root of trust.Type: GrantFiled: March 19, 2020Date of Patent: October 11, 2022Assignee: Arista Networks, Inc.Inventors: Ethan Rahn, Ritesh Kumar Sinha, Andre Pech
