While Digital Transformation has become one of the hottest topics in the IT industry, it is also somewhat nebulous and thus runs the risk of being marketed as all things to all people. The purpose of this study is to find out what the story is behind the hype.

Steven Taylor - Editor-in-Chief, Webtorials
Voice over IP (VoIP) is no longer tomorrow's technology. High-speed networks that support quality-of-service (QoS) technology have come a long way in mitigating performance and availability issues. But what about security?

The goals of the 2018 Guide to WAN Architecture and Design (The Guide) are to discuss the state of WAN architecture and design with an emphasis on the current SD-WAN solutions, and to provide insight into the emergence of solutions that leverage the key concepts of SDN and NFV to support all components of the WAN edge.

This e-book provides insight into the currrent state of the WAN based on the survey results received from over 100 network professionals in March and April, 2017.

This study looks at how respondents communicate, how much time they use each communication mode including face-to-face meetings, email, telephone calls and conferences, video conferencing, Chat/Text/Instant Messages and online tools.

Dr. Jim Metzler's annual Guide to WAN Architecture and Design - what you need to know about the most current statistics, trends and analysis regarding the State of the WAN.

What you need to know about the most current statistics, trends and analysis regarding the State of the WAN in 2017. Jim Metzler's annual State of the WAN Results and Executive Summary - a must-read for any professional involved in enterprise technology.

It's a new year and a new WAN. Jim Metzler shares his research and guidance with a best-practices roadmap for enterprise network organizations to follow for a successful transition to the new WAN.

​The primary goals of The​ 2017 Guide to WAN Architecture and Design​ are to make enterprise network organizations aware of the emerging alternatives to the traditional approaches to WAN architecture, management and security and to help them understand the key differences in those alternatives.

I'm continually surprised by how often enterprise procurement managers - and their lawyers -- insist on obsolete clauses even as they de-emphasize or skip terms that are crucial in a digital world.

Yes, I signed the petition urging the Federal Communications Commission (FCC) to regulate the Internet as a communications service. But...

Topics include how WAN budgets are changing, how organizations are approaching the adoption and deployment of Software-Defined WAN (SD-WAN) functionality, and what factors drive or inhibit a SD-WAN.

The goal of this TechNote is to contrast the traditional approach to designing a branch office WAN with two emerging WAN architectures. One of those emerging architectures is a Software Defined WAN (SD-WAN) and the other is a Secure Cloud Network.

The 2016 Guide to SDN & NFV is designed by Dr. Jim Metzler to eliminate the confusion that surrounds SDN and NFV and to accelerate the analysis and potential adoption of these new architectural approaches.

Most organizations are still waiting to adopt Software Defined Networking (SDN) and Network Functions Virtualization (NFV)

There was a time when troubleshooting a voice problem was tedious but well-defined; however, when a Voice over IP connection is 'breaking up,' what's a tech to do, just call your network administrator?

While Unified Communications (UC) is a suite of capabilities, collaboration is a behavior.

This report, authored by leading industry analyst Dr. Jim Metzler, presents current market research on the factors that are impacting the WAN as well as providing insight into what network organizations feel about the viability of Software Defined WANs (SD WANs).

Topics covered include traditional and evolving models, virtualization, optimization, and security.

This executive summary is the fourth installment of a four-part series written by Dr. Jim Metzler.

The 2015 Application and Service Delivery Handbook, written by Dr. Jim Metzler, helps IT organizations understand and respond to the emerging application and service delivery environment: this third installment focuses on what has to happen to improve the management and security of applications and services.

Dr. Jim Metzler observes that before the advent of SD-WANs, there hadn't been any fundamental enhancements to WAN technologies or services in a decade: fortunately SD-WANs can make a difference in the performance of unified communication- most notably when using Skype for Business.

This Webtorials State-of-the-Market Report provides quantitative insights and qualitative analysis on how IT professionals are using WebRTC today and how they plan to use WebRTC in the coming year.

Unified Communication (UC) in the cloud is a favorite subject of many papers, webinars, podcasts, press releases, and articles. The hype is not wrong, but it often leaves out the reasons to stay with an on-premises system and it inflates the reasons to use a cloud-based UC solution.

With hyper-connectivity for multiple media and decentralized applications, unified communications, and virtualization all happening at once, the enterprise needs an architectural framework to make it all work together.

This note discusses why a session border controller (SBC) is essential to evolving UC deployments, with a focus on why an SBC is especially important when deploying Skype for Business.

If it works, keep it. That is what many in the IP community are saying even though we are rapidly running out of IPv4 addresses to allocate.

This advisory, written by Larry Hettick, looks at what comes after unified communications.

Voice over LTE (VoLTE) is evolving as the platform of choice for delivering mobile voice calls.

Webtorials has just completed the data collection phase for the 2015 WebRTC State-of-the-Market report, and we have found that IT managers are notably more familiar with WebRTC this year than last.

LTE's faster mobile broadband speeds, the explosion of smart phones and the number of concurrent data sessions running across LTE presents a significant network management challenge: fortunately, tools such as diameter are available to address it.

The path to replace the PSTN with a fully VoIP-based network won't be easy, with roadblocks and detours that will need to be solved before any carrier can retire their PSTN.

A modestly skilled hacker can access pretty much anything that is digital, placing your company's loss and your liability into the headlines.

As SIP explodes beyond connecting VoIP calls to a plethora of communication modes, the hyper-connected contact center must adopt security measures to provide a new level of protection.

Two of the hottest topics in networking are SDN & NFV. While both enterprises and service providers have acknowledged interest, the majority remain on the sidelines or in the analysis stage of adoption. This Guide addresses the confusion surrounding SDN & NFV, accelerating the analysis and potential adoption of these new design and architectural approaches.

In the past, wireless network designers were most concerned about the area of physical coverage and bandwidth. The number of wireless devices supported was not an issue. The IoT, however, changes everything. Where coverage was once the goal, now capacity, device population, and performance are the driving design goals.

Executive SummaryJim Metzler, Ashton Metzler & AssociatesDistinguished Research Fellow and Co-FounderWebtorials Analyst Division...

Replacement of the PSTN with a global VoIP-only network delivering service provider wired voice and wireless voice is not a question of if, but when.
