Network Performance Management (NPM)

Arista EOS® has been designed for advanced telemetry from the start. The key is the state-based software architecture of Arista EOS. Arista EOS platforms store all real-time state in one common database, SysDB, easily accessible through APIs and SDKs. With the software infrastructure enhancements to NetDBTM, EOS-based devices are able to stream every state change from every device into an aggregated network-wide view.:

  • Network state in real-time
  • Dynamic workloads in virtualized and containerized environments
  • Advanced monitoring and instrumentation for troubleshooting

TAPs, Aggregators, Packet Brokers and Metadata

Arista offers a new approach to TAP Aggregation that delivers security, availability and data analysis for high density, non-blocking 10/25/40/50/100GbE networks at any scale– all powered by Arista EOS® software to deliver an order of magnitude improvement in the economics of building cloud-scale visibility.

Next generation TAP Aggregation using Arista CloudVision® with Arista Data ANalyZer (DANZ) makes it possible to cost-effectively and losslessly monitor all datacenter network traffic, while capturing and analyzing only the traffic that is needed. DANZ is a precision visibility architecture that can scale to thousands of access points and hundreds of Terabits bandwidth.
