Enhanced Features for High Performance Cloud Networks

The Arista 7280R3 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)

To meet the stringent timing and synchronization requirements for modern 5G as well as media & entertainment networks,  Arista’s

hardware delivers high precision in-band time and frequency distribution support via Precision Time Protocol (PTP, IEEE 1588v2) and

Synchronous Ethernet (ITU G.8261). As part of PTP support, Arista platforms deliver both Boundary and Transparent clock modes. In

addition, PTP profiles (8275.1 and 8275.2) with full and partial timing support allows flexibility of time distribution end to end.

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 7280R3 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 7280R3 is the perfect solution for transit gateway between EVPN domains connected over MPLS.

7280R3 Deterministic Network Performance

The Arista 7280R3 Series uses a deep buffer virtual output queue (VOQ) architecture that eliminates head-of-line (HOL) blocking and

virtually eliminates packet drops even in the most congested network scenarios. An advanced traffic scheduler fairly allocates

bandwidth between all virtual output queues while accurately following queue disciplines including weighted fair queueing, fixed

priority, or hybrid schemes. As a result, the Arista 7280R3 can handle the most demanding data center requirements with ease,

including mixed traffic loads of real-time, multicast, and storage traffic while still delivering low latency.

FlexRouteTM

The Arista FlexRoute Engine provides support for the full internet routing table, in hardware, with IP forwarding at Layer 3 and with

sufficient headroom for future growth in both IPv4 and IPv6 route scale to more than 1.4 million routes. The innovative FlexRoute

Engine with its patented algorithmic approach to building layer 3 forwarding tables on Arista R-Series Universal Spine and Leaf

platforms is unique to Arista and a key enabler in calling these platforms routers. The large scale 7280R3K Series expand FlexRoute

support to over 5M routes.
