Building Modern Networks

By: Steven Noble

Overview of this book

<p>As IT infrastructures become more software-defined, networking operations tend to be more automated with falling levels of manual configuration at the hardware level. Building Modern Networks will brush up your knowledge on the modern networking concepts and help you apply them to your software-defined infrastructure.</p> <p>In this book you'll gain the knowledge necessary to evaluate, choose, and deploy a next generation network design. We will cover open and closed network operating systems (NOS) along with the protocols used to control them such as OpenFlow, Thrift, Opflex, and REST. You will also learn about traffic engineering and security concepts for NGNs. You will also find out how to fine-tune your network using QoS and QoE.</p> <p>By the end of the book, you'll be well versed in simplifying the way you design, build, operate, and troubleshoot your network.</p>

Where to Start When Building a Next Generation Network

Assembling the network


Let's see a few standard design points before we explore into the setup in depth.

Now that we know the power/cooling needs of the solution we have decided on, we can provide the data to the facilities manager and start assembling the necessary hardware, preparing the space, and ordering the accessories.

One thing that is important when planning the design is remote manageability. Some key pieces to have in the racks are remote management capabilities including power cyclers, console capabilities, and a secure management network.

For each rack, you will want at least two separate power circuits coming from separate panels, which will be used to feed any equipment with multiple power supplies. It is also key to log all of this data for future reference in the event that something happens.

Burning in the equipment is also important, so plan for at least a week of running the equipment before using it in production.
