SD-WAN: Link-State Monitoring & Dynamic Path Selection

Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology will be explored. There are two areas of WAN connectivity that often bring frustration – availability and performance. Link-state monitoring enables a routing device to […]

How Many SSIDs Should An Enterprise Wi-Fi Network Have?

David Coleman, CWNE#4 and Sr. Product Evangelist, and Chris Harkins, Sr. Technical Instructor discuss best practives on SSID design. If you’ve ever wondered why you shouldn’t use 16 SSIDs, be sure to watch this video.

What is SD-WAN? – Reference Poster

Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. We are in the process of publishing a 5-part blog series on the key components of SD-WAN, but what about something that is easier to digest and reference? It’s here! A one-page, vendor-neutral reference poster that covers […]

SD-WAN: Policy Unification

Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology will be explored. In a previous post, the benefits of centralized orchestration were discussed. Centralized orchestration creates an effective platform for policy unification. There are […]

SD-WAN: Centralized Orchestration

Software-Defined Wide Area Networking (SD-WAN) is an innovative new approach to the deployment, management and operation of WANs. In this 5-part series, the key benefits of this exciting new technology will be explored. Part 1: Centralized Orchestration Problems often arise when an organization experiences growth and expands its outreach to other locations. Unfortunately, positive business […]

Why Is OFDMA One Of The Most Important Features In 802.11ax?

Last week, I wrote about Target Wake Time (TWT), and how it was a key feature for IoT and mobile devices in 802.11ax. As exciting as that feature is, OFDMA is arguably the most important new feature correlated to 802.11ax. As a refresher, OFDMA stands for orthogonal frequency division multiple access. OFDMA is a multi-user version of […]

How Will Target Wake Time Help Mobile Devices And IoT In 802.11ax?

As mentioned in a previous post, 802.11ax adds some exciting power saving enhancements and improved resource scheduling features including scheduled sleep and wake times, which is borrowed from 802.11ah. Let’s dive a little deeper. Target Wake Time (TWT) allows devices to negotiate when and how often they will wake up to send or receive data. […]

What Is BSS Coloring In 802.11ax?

Last week, we looked at the new features that 802.11ax brings to the 802.11 standard. Let’s take a closer look at BSS Coloring this week. BSS Coloring was a mechanism originally introduced in 802.11ah to assign a different “color” per BSS. Why? To increase capacity in dense environments, we need to increase frequency reuse between […]

What Does 802.11ax Change About The WLAN Standard?

Last time, we looked at the goals of the 802.11ax standard. Let’s break down some of the important changes 11ax introduces (in no particular order). First introduced in 802.11ac, MU-MIMO technology theoretically allows the simultaneous transmitting of multiple frames to different receivers at the same time on the same channel using multiple RF streams to provide […]

What Are The Goals of The 802.11ax Standard?

Last time, we looked how at 802.11ax is going to address common Wi-Fi problems. Before getting more into HOW it’s going to do all these things we need to go back to the basics for a minute. As a reminder, RF is a half-duplex medium, which means that only one radio can transmit on a […]
