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>

NSX


Now, let's begin with the NSX product. It consists of two parts: the NSX Manager and the NSX Controller.

NSX Manager

NSX Manager is the central management pane for all NSX-related objects within the data center. It provides multiple interfaces, including a User Interface (UI) and an Application Program Interface (API). It is also responsible for installing the vSphere Installation Bundle (VIB).

The VIBs included with NSX are as follows:

  • VXLAN: Provides VXLAN support to vSphere
  • Distributed routing: Allows routing between VMs without leaving the NSX network
  • Distributed firewall: A kernel-level firewall that can be offloaded onto a smart Network Interface Card (NIC)

NSX Controller

NSX Controller is the central manager for NSX virtual networks and overlay technologies. All information about logical switches, connected devices such as virtual machines, and hosts is managed by the NSX Controller.
