Buckle up, IT pros, and move over SDN: Intent-based networking (IBN) is the latest approach to network management that’s buzzing in the enterprise space. While this acronym may not be as familiar as others that have come to define IT ops and digital transformation (think SD-WAN and SaaS), it’s not actually an entirely new approach. In fact, IBN shares a...

Before the days of personal computing -- and well before the dawn of smart devices -- it was easier for the relatively few users leveraging the Internet to recognize familiar IP addresses, like memorizing a home phone number in the pre-caller ID days. While we may type URLs into search bars and click “Send” on email, computers don’t actually read...

Modern Networking Technology Takes Center Stage for IT in 2018
by Christine Cignoli on

Here’s a helpful explainer on intent-based networking, which we’ve heard a lot about from Cisco in the past year or so. The idea of intent-based networking is essentially to bring a kind of automation to networking, but an automation that takes into account the complexity and rigged-together nature of many networks. Intent-based networking aims to model ideal outcomes rather than...

How Smart Networks Are Changing Corporate Networks
by Andrew Sanders on

The WAN used to be controlled by hardware switches and physical cabling. Although this is still the case in many companies, a number of businesses have set up something entirely new—a fully programmable WAN. This is an upheaval. It brings many changes to the discipline of information technology, such as: How architects design their networks How companies procure network hardware...

Software-Defined Network Elements Slowly Come to IT
by Christine Cignoli on

On the road toward software-defined everything, WAN virtualization could play an important part. SDN is useful for a lot of data center networking tasks, like switching. But SDN across existing IP networks doesn’t necessarily bring a lot of value, and many businesses wouldn’t be able to afford to invest in entirely new software-defined networks. SD-WAN, though, has emerged as a...

For every new technology, there’s that initial excitement that makes you think “this is the innovation that will break the Gartner Hype Cycle.” But time and time again, there’s a gap between innovation hype and practical implementation. There’s no better example of this gap than the case of software-defined networking (SDN). The concept has been around since the mid-1990s, but...

The Digital Network Revolution Is Here
by Christine Cignoli on

Check out this research showing how digital transformation is affecting companies with remote and branch offices. The EMA Research study found that 83% of enterprises are increasing their number of WAN-connected sites, and in 84% of enterprises, the number of network-connected devices is also increasing at remote sites. A majority of businesses surveyed—74%—are also making changes around using the internet...

Can Emerging Network Technologies Solve IT's Problems?
by Christine Cignoli on

One of our favorite topics around here is obviously network performance. This take on upgrading network performance looks at the big picture of networking today to see where improvements might happen. Throughput and security have traditionally been the two big considerations in network performance, but others now include policy-based approaches, flexible infrastructure and capacity. The general outlook here is that...

The Network Plays Catch-Up
by Christine Cignoli on

A company’s network is its transportation system, essential to daily work getting done.  It’s gotten more complex through the years, but the underlying technology used to move packets of data from place to place hasn’t evolved much. In that time, though, applications have moved from on-premises data centers to hosting via the web, or delivered as a service—and the network...
