Using TRILL, FabricPath, and VXLAN: Designing Massively Scalable Data Centers (MSDC) with Overlays

Introduction

Over the past few years, virtualization and the cloud have become exceedingly popular. The recognition that server resources including memory, CPU, and so on are severely underutilized in large data centers has led to virtualized data center deployments. Physical servers now constitute a number of virtual servers that each cater to different application needs. Architectures are sought for deployment of public clouds, private clouds, and more recently hybrid clouds. Network architects are thus faced with challenges in the design and implementation of massive scale data centers that serve these challenging requirements. To address the requirements, this book describes data center deployments using overlay technologies with emphasis ...
