Enhanced Features for High Performance Cloud Networks

The Arista 7280R3A Series delivers a suite of advanced traffic control and monitoring features to improve the agility of modern high

performance environments, with solutions for automation, data monitoring, precise timing and next-generation virtualization.

Automating the data center enables customers to dynamically provision computing resources in the most efficient manner while also

meeting business needs by maintaining service level agreements (SLAs). Arista EOS automates complex IT workflows and simplifies

network operations while reducing or even eliminating downtime. Arista EOS rich automation capabilities not only reduce the human

error element in network operations but also enable IT operators to make the network work the way they want.

Arista offers solutions for a variety of approaches to cloud-like network automation. Addressing the needs of the largest public cloud

environments as well as applying those lessons learned in the turnkey CloudVision automation offering.

CloudVision

CloudVision is a network-wide approach for workload orchestration and workflow automation as a turnkey solution for Cloud

Networking. CloudVision extends the EOS publish subscribe architectural approach across the network for state, topology, monitoring

and visibility. This enables enterprises to move to cloud-class automation without needing any significant internal development.

Precise Data Analysis

Arista Latency Analyzer (LANZ) and Precision Data Analyzer (DANZ) are integrated features of EOS. DANZ provides a solution to

monitoring and visibility challenges at 100Gbps and 400Gbps giving IT operations the ability to proactively deliver feedback on

congestion events, filter, replicate, aggregate and capture traffic without affecting production performance. LANZ provides precise real-

time monitoring of micro-burst and congestion events before they impact applications, with the ability to identify the sources and

capture affected traffic for analysis.

Precision Timing (IEEE 1588 and SyncE*)

Many modern and emerging applications are using precision timing as part of their service delivery requirements including 5G, Media

production, manufacturing, IoT sensors, high frequency trading etc. To meet the stringent timing and synchronization requirements,

Arista’s hardware delivers various timing solutions, including high precision in-band time and frequency distribution support via

Precision Time Protocol (PTP, IEEE 1588v2) and Synchronous Ethernet (ITU G.8261) as well as flexibility of time synchronization via

external timing ports. It also supports Class C timing, to meet the enhanced accuracy requirements at the edge of the 5G networks. As

part of PTP support, Arista platforms provide both Boundary and Transparent clock modes as well as PTP profiles (8275.1 and 8275.2)

with full and partial timing support allowing greater flexibility in the distribution of end to end timing solutions.

Virtualization

The foundation for Arista's Network Virtualization solutions is VXLAN, an open IETF specification designed to standardize an overlay

encapsulation protocol. Arista solutions range from OVSDB and Openstack integration to BGP EVPN in conjunction with EOS

CloudVision®, a platform for network-wide workload orchestration and workflow automation.

The 7280R3A builds on the deep buffer wire-speed gateway with EVPN/VXLAN for layer-2 and layer-3 stretch within data center as well

as DCI use cases. The 7280R3A is the perfect solution for transit gateway between EVPN domains connected over MPLS.

Inband Network Telemetry

Inband network telemetry, or INT, is a standards approach to providing deep visibility into traffic in real-time, with no impact on switch

performance. INT provides per-flow monitoring of traffic drops, latency, congestion and the network path. INT information can be

exported in IPFIX or sFlow formats to a management system or collector such as Arista CloudVision, for predictive analytics and deep

forensics to measure latency per device and across the network, trace packets and reconstruct path topology as well as detecting hot-

spots. Inband Network Telemetry is available on the 7280R3A, 7280R3AM and 7280R3AK Series of products, with the ability to originate,

pass and terminate, along with mirroring to external collectors.
