Gartner predicts: SD-WANs to replace routers, but which SD-WAN is the question
That SD-WANs will replace routing was not the most important message from last week’s Gartner webinar with Gartner vice president and distinguished analyst Joe Skorupa. No, the biggest message came in some startling statistics. Half the market revenue is held by just two startups, which begs the question: With 30-plus vendors in the SD-WAN space, are you […]
Is Your WAN Ready for the Cloud?
Historically, and to this day, the Wide Area Network (WAN) has been all about physical locations. Branches, remote offices, retail stores, hospitals, and manufacturing sites all needed to be connected to a central location – the data-center. The process of deploying connectivity to all locations and ensuring service levels and proper response times has not evolved […]
Broadband Everywhere with One Invoice
I speak to many companies considering SD-WANs. A common question is, “how could we possibly manage all the different invoices and customer service numbers required if we shift our network to broadband?” Looking for an MNO? Check out our MNO checklist This perceived problem is not a problem at all. You see, Managed Networks Operators (MNOs) (also called Global […]
Network Availability With Multiple WAN Circuits
Network availability and resilience are important values of SD-WANs. By using multiple low cost internet circuits, with the addition of LTE, you can reach a network availability that theoretically will never fail, rather cost effectively. While your particular requirements might still require a primary MPLS path, the same mathematics applies. Your various WAN circuits will be operating in parallel, […]
An SD-WAN and MPLS Pricing Scenario
It’s pretty much axiomatic among SD-WAN providers that organizations can save money by switching to SD-WANs. The low-cost of Internet services relative to MPLS services allows companies to reduce their monthly spend on bandwidth “by as much as 90%” as some SD-WAN providers claim. Here at SASE Experts, we’re not tied to any one technology, recommending SD-WANs or MPLS […]
No More Routing
A customer of mine and I were chatting over lunch the other day, and our conversation turned to what was going on with his network. His routers were coming end-of-life. I asked him what his plans were, and he looked at me with a blank stare and said: “Upgrade them, of course.” I do not […]
Service Chaining
Service chaining is getting a lot of attention recently. What does it matter? Let’s look at a very simple example, illustrated below. In the upper part of this image, a host (in this case a laptop, just for example), transmits a packet through the network towards a server located beyond D (see right side). This packet is […]
SASE Experts to speak at SD-WAN Summit
The most renowned experts in the SD-WAN field will present the latest information at the SD-WAN Summit to be held in Novotel Paris Roissy CDG, September 20-22, 2016. This conference is a natural outgrowth of the MPLS+SDN+NFV World conference held in March. Software-defined wide-area networks support branch office connectivity in a simplified and cost-effective manner. SD-WAN provides new features that […]
SD-WAN Misconceptions
SD-WAN is having is effect on the future of the Wide Area Network, today. Much is said about it, but little is truly understood. The misconceptions of its effect on the WAN are widespread. Since our business is all about evaluating and implementing these technologies, let’s clear things up. SD-WAN allows you to use multiple WAN connections […]
BGP or PFR for WAN Survivability
Are you considering redundancy to protect your network for a fiber cut or local network failure? While using an internet VPN as a secondary network is a common backup solution (using BGP), the right SD-WAN solution can provide a more seamless fail-over in less than a second. Some SD-WAN technologies will even maintain a VoIP or video […]
