Infrastructure & Performance at Webtorials  

Steven Taylor - Editor-in-Chief, Webtorials
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.

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.

Nearly 1000 professionals participated in the SIP survey. In its sixth year, the survey evaluates SIP trunking, specifically to document the most common issues that occur during SIP trunk implementations and what can be done to help mitigate these issues - or not.

​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.

Multiprotocol Label Switching (MPLS) virtual private networks (VPNs) have long been the darling of the enterprise WAN. Secure, reliable, and high-performing, they offer business-grade traffic control features particularly well-suited to carrying real-time and business-critical data.

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.

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.

Author Mike Finneran of dBrn Associates, Inc. pinpoints the five big drivers that will define the enterprise landscape in 2016.

Becoming a 'SIP School Certified Associate' or SSCA® proves to the world that you both understand the protocol called SIP and can work in the ever evolving world of Voice over IP.

This independent research investigates the impact Avaya's networking technology (Fabric Connect) has had on its customer base.

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.

According to Gartner, "the IPS market must respond to the pressure coming from the uptake of advanced threat defense solutions and the requirement to provide cloud placements."

According to a recent study by Nemertes Research and based on feedback from a wide range of decision makers/influencers, Avaya offers the lowest Total Cost of Ownership (TCO) for large contact centers.

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.

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.
