Summer Network Research Roundup

by Andrew Lerner  |  July 28, 2017  |  Submit a Comment

Note:  I haven’t been able to blog as much as I’ve wanted to recently (…the product of having a 12 year old and 12 week old), but wanted to provide a little insight on several pieces of research we’ve published recently…

Data Center Networking Magic Quadrant

This Magic Quadrant covers 13 vendors that provide hardware and/or software solutions to deliver connectivity within enterprise data centers. I won’t go into great detail here on the vendors and their placement but will point out that two vendors met inclusion for the first time this year:  Cumulus and Big Switch. This is indicative that the real product differentiation is in software and the massive need for highly automated solutions. Not surprisingly, the need for “network agility” is a major driver for investment in data center networking technology. As we pointed out in the research, the three primary market drivers are

  • Replacement of existing data center switches that are becoming obsolete
  • Expansion of network infrastructure to support new applications/services
  • Adoption of new solutions to increase agility, ease of operations and cost-effectiveness of existing infrastructure

You can catch the full report here.

Enterprise Networking Hype Cycle

This enterprise-focused Hype Cycle evaluates the networking and communications technologies that are emerging, have become widely adopted, and are being hyped by the service providers, vendors and the press (and analysts/bloggers). This year, we cover 33 network technologies, with several technologies are hangin’ round the peak of inflated expectations, including vCPE, SDWAN services, 25/50 Gig Eth, and SDP (Software-Defined Perimeter).  I remember the good ole days when SDN stood alone.  Meanwhile technologies like Ethernet Fabrics (18,000 production deployments now) and Hybrid WANS are climbing the slope enlightenment towards the plateau of productivity.  On the horizon, several new technologies are emerging including 5G, Intent-based networking, and OCP just to name a few. Within the hype cycle, we go beyond just placement and dive into the definition, market position/adoption, business impact and provide advice about the technology. And despite the hype, way too often, legacy runs the world.

Best Practices for Implementing Wireless Network Guest Access

…because we all (regularly) attend meetings where the WiFi password is scribbled on the whiteboard… or on a post-it

Summary: Unauthenticated wireless connectivity for guest access is a disaster waiting to happen. IT infrastructure and operations leaders responsible for planning network infrastructure need to apply policy enforcement and understand the needs and characteristics of each usage scenario.
