For years, virtual LANs have played an important role in basic enterprise networking, enabling engineers to segment portions of their networks for security, management and scalability. The emergence of virtualization and cloud computing networks only makes understanding VLAN implementation more important. VLANs are key to providing management in a world of virtualization, even where virtual machines are constantly migrating, challenging the very basics of network management. In this guide, learn about old and new uses of VLANs in everything from wireless LANs to data center networks.

802.11n design best
In the this tutorial you’ll discover best practices for designing and deploying 802.11n, a wireless LAN (WLAN), from RF design and band/channel selection to access point placement for coverage and capacity. After reading this section, you will understand where to start when adding 802.11n to your wireless LAN and the key factors that must be considered during the design process.
Cloud computing network
The definition of cloud computing changes readily, so the definition of cloud computing networks changes as well. Ultimately, the goal of cloud computing – regardless of model – is to create a fluid pool of resources across servers and data centers that enable users to access stored data and applications on an as-needed basis. Cloud computing networks, therefore, have two missions: to enable the movement of that pool as a single virtual resource, and to connect users to these resources regardless of location.
