Testing Identifies Source of SD-WAN Internet Performance Problems

Enterprise networkers can be forgiven for thinking that running mission-critical apps across an Internet-based SASE SD-WANs sounds like a recipe for disaster. After all, can an inherently unpredictable network like the public Internet really provide predictable application delivery? We recently explored that question in a series of tests conducted for one of our clients. We measured latency […]

High Performance Broadband in Minutes??

High Performance Broadband in Minutes?? I don’t know about you, but I have experienced the MPLS carrier installation that never happens.  An entire network implemented, but one or two locations that take four, six, eight months.  So frustrating! Today in most places you have two quick installation options: broadband internet and LTE or 3G over the air. […]

MPLS Compared with Frame Relay and Internet VPN

MPLS Compared with Frame Relay and Internet VPN Internet VPN With the drop in the cost of Internet bandwidth and VPN hardware, many companies utilize hardware based Internet VPNs for their Wide Area Networks. This historically has been cost effective with satisfactory performance. But as application requirements change, the Internet can become an unsatisfactory medium […]

Internet Bandwidth Costs Have Dropped

Internet Bandwidth Costs Have Dropped When MPLS networks came on the scene, the internet did not have the global backbone in place the way it is today. Packet loss and congestion were common place. And the T1 or E1 was considered a “big pipe” by many. The global internet cable infrastructure is now enormous. You […]

Internet Variability and SD-WAN- ONUG 2018

The annual NY meeting of the Open Network User Group (ONUG) has just ended, with over 1000 attendees from major enterprises in attendance.  I had the honor of presenting research results about the internet CORE, which discussed my empirical research of the variance of internet latency between different paths around the world.  You can view my […]

Internet Core Stability Solved – Mode Introduces SD-Core Backbone for SD-WAN

Anyone who wants to minimize the latency of their Internet-based SD-WAN connection should avoid the Internet core. But how do you do that? A global, independent backbone offers an excellent alternative. Until recently, Aryaka and Cato Networks were the only providers of a global, independent backbone. A new player, Mode, just emerged from stealth with significant pedigree and introducing its own […]

SDN or SD-WAN and MPLS Networks: Will the Internet Be Your Next WAN?

To hear the press tell it, the MPLS network is all but dead. The Internet is the future of wide area networks (WANs) in what’s been called a software-defined WAN (SD-WAN), also referred to as SDN. The reality, though, is a bit more complex to say the least. After almost a decade building MPLS and Internet VPN […]

WAN using IP VPN over Internet vs MPLS – Pros and Cons

IP VPN over Internet vs MPLS, there’s a price for everything in this world, and  Internet based IP VPNs are no exception. While  IP VPNs over Internet are a cheaper alternative to any MPLS network, it doesn’t necessarily mean they’re for everyone, as customer requirements always vary. In this posting, I will explain both the Internet IP VPN advantages […]

Video Conferencing – how to dial from MPLS network to Internet?

If you use video conferencing, an MPLS network with improve the quality of your performance enormously.  If you use Telepresence, then MPLS or VPLS is a requirement, when you consider what you spent on the hardware.  Since an MPLS network has Quality of Service, you will eliminate freeze frame, blur and disconnects that running video over the […]
