Data Center Network Modernization Briefing
The Data Center Network (DCN) is essential for supporting high-performance workloads, including Artificial Intelligence (AI). This briefing will explore next-generation data center architectures, highlighting the advantages of using an underlay/overlay topology and controller-based management. As DCN architectures become more complex, day-two operations software becomes increasingly necessary. This session will provide an overview of DCN hardware, architectures, and day-two operations, along with a brief introduction to the most commonly seen DCN OEMs in enterprise data centers.
The Battle of AI Networking: Ethernet vs InfiniBand
This article is not an exploration of who does Ethernet better so much as a direct examination of technology itself. Numbers will be reported as an aggregate means between major players in the AI Networking market and contrasted with equivalent InfiniBand performance. The goal is to answer, at an atomic level, one question: eliminating all other variables, is Ethernet good enough?

Arista EVPN VXLAN 101 Lab
This Arista MP-BGP EVPN Lab provides exposure to the new technology and capabilities of the products used. This lab introduces the Arista Cloud Vision Portal(CVP) and introduces students to the basics of building the VXLAN L3LS Underlay, MP-BGP overlay, MLAG, Asymmetric and Symmetric IRB, and eternal L2/L3 connectivity. It also provides an in-depth look at Arista Cloud Vision Portal(CVP) and how to use it for day 0,1 building and day 2 operations. 3 VXLAN EVPN scenarios based on best practices from the Arista design guides, ACE3 course material, Arista TAC support the Arista EOS forum posts. There are many different ways to create an Arista-based VXLAN EVPN fabric; these labs present a migration phase from a standard 3 tier VLAN and SVI-based network to a VXLAN fabric, Then the fabric changes to using Asymmetrical IRB and Symmetrical IRB. BGP routing is the underlay, overlay and connectivity to the remote data center under migration.
Programmability and Automation Meetup: Automated Software Image Management
Software Image Management (SWIM) is a repeatable framework where engineers can produce repeatable, safe outcomes for efficient device software upgrades. This results in a faster response to vulnerability management, more predictable maintenance schedules, and hours of an engineer's life saved in the middle of the night.
In this session, Bob Longmore from World Wide Technology helped us answer the question- What if we used AAP and EDA to decouple the tasks involved in this workflow?
Intent Based Networking with Juniper Apstra
This lab will enable a student to build a basic Multi-Site fabric using Apstra for complete end-to-end connectivity.
Introduction to Arista's AI/ML GPU Networking Solution
AI workloads require significant data and computational power, with billions of parameters and complex matrix operations. Inter-network communication accounts for a significant portion of job completion time. Traditional network architectures are insufficient for large-scale AI training, necessitating investments in new network designs. Arista Networks offers high-bandwidth, low-latency and scalable connectivity for GPU servers, with features like Data Center Quantized Congestion Notification and intelligent load balancing. Arista's AI Leafs and Spines provide high-density and high-performance switches for AI networking. Different network designs are recommended based on the size of the AI application. A dedicated storage network is recommended to handle the large datasets used in AI training. Arista's Cloud Vision Portal and AI Analyzer tools provide automated provisioning and deep flow analysis. Arista's IP/Ethernet switches are well-suited for AI/ML workloads, offering energy-efficient interconnects and simplified network management.

Arista Automation Lab
This lab is designed to expose network engineers to Arista-oriented automation techniques. The focus is mid-level programmability leveraging CloudVision Portal, Ansible, Jinja2,and Python.
Arista With Cloud Vision Portal Sandbox Lab
This lab provides exposure to the new technology and capabilities of the Arista products used. This lab introduces the Arista Cloud Vision Portal(CVP) and includes 3 VXLAN EVPN scenarios based on best practices from the Arista design guides, ACE3 course material and Arista TAC support the Arista EOS forum posts. There are many different ways to create an Arista-based VXLAN EVPN fabric; these 3 lab scenarios presents 1) a migration phase from a standard 3 tier VLAN and SVI-based network to a VXLAN fabric, 2) using Asymmetrical IRB and 3)Symmetrical IRB. BGP routing is the underlay, overlay, and connectivity to the remote data center under migration. This sandbox and configs can be further used to explore other configurations and functionality of Arista CVP.
Arista Universal Cloud
There are several universal architectures in the Arista design portfolio. The Enterprise Universal Cloud Network can be used in the data center and in the Cognitive Campus, and the Enterprise Anycloud Network expands beyond the data center. All of these designs deliver the Arista Unified AnyCloud Architecture offering unified orchestration, management and telemetry with CloudVision.
Arista's guiding principles are Universal(Common architectures from small to huge), Simple(a single operating system for all platforms and hardware), Open(standards-based features and functions), Programable(Easy to use APIs and automation), and Visible(Full state Telemetry and flow information)
The key to these guiding design principles is the use of the Arista EOS architecture for its hardware and software-based devices. EOS is based on a Linux kernel, standard and fully open. EOS uses agent processes, that use a Publish/Subscribe model to populate the NetDB on each device which contains all device states. NetDB can then be used by Aristas CloudVision products to offer full-state telemetry and flow information for the entire Universal Architecture. Because Arista is using a single binary for all hardware and software-based devices Arista can implement hardware abstraction. Unlike some other manufacturers, Arista uses the latest Merchant Silicon and when coupled with the standard open EOS kernel allows very fast development cycles, fewer bugs, and faster adoption by customers since it is the same EOS.
