Modern Data Center Fabrics

Welcome to the Modern Data Center Fabrics course. In this course, we will explore the architecture and protocols used in modern, scalable data centers.

Spine-Leaf Architecture

Traditional 3-tier architectures (core, distribution, access) have been largely replaced by the Spine-Leaf topology in modern data centers. This topology offers predictable latency, high bandwidth, and non-blocking paths.

VXLAN (Virtual eXtensible LAN)

VXLAN is a network virtualization technology that attempts to address the scalability problems associated with large cloud computing deployments. It provides a MAC-in-UDP encapsulation to extend Layer 2 segments over a Layer 3 underlay network.

BGP EVPN

Ethernet VPN (EVPN) is an extension to BGP that allows the network to carry Layer 2 MAC addresses and Layer 3 IP addresses simultaneously. It serves as a highly scalable control plane for VXLAN.
