"This class is for anyone with a pretty good handle on networking basics who wants a deeper understanding of switching, routing, management and virtual networking. The course concentrates on the concepts, equipment, and protocols used in the Layer 2 (data link), Layer 3 (network), and Layer 4 (transport) components of the OSI networking framework. You'll learn advanced techniques for managing and troubleshooting the infrastructure of wired and wireless...

Go beyond layer 2 broadcast domains with this in-depth tour of advanced link and internetwork layer protocols, and learn how they enable you to expand to larger topologies. An ideal follow-up to Packet Guide to Core Network Protocols, this concise guide dissects several of these protocols to explain their structure and operation. This isn't a book on packet theory. Author Bruce Hartpence built topologies in a lab as he wrote this guide, and each chapter...

"Virtualization is central to modern communications. From cloud services to internal compute clusters, virtual machines and hypervisors play an ever growing role in client-server communications and in design discussions. But virtualization is not limited to servers. Virtual private networking, virtual circuit and logical topologies have used many to one ratios to describe the relationship between logical connections running over physical pathways....
