The Importance of Application Intelligence in SD-WAN

As we look at the field of SD-WAN we begin to see the importance of going beyond simple protocol and port recognition in achieving the nirvana of true policy controls for performance and security. First generation SD-WAN allowed for rudimentary traffic control via protocol and port identification in much the same way that it is handled via access lists on routers. This was sufficient for in house applications that didn’t change address ranges, or ports and could be statically defined. However, it poses a problem when being used with current and future SaaS applications that are constantly evolving in complexity and capability. Continue reading

Refactoring the Network

The fundamental shift of the enterprise toward the cloud has posed a conundrum for many. The largest issue is the state of most enterprise networks. These networks were designed for an era gone by. Their original designs could not foresee the coming of technologies such as SDN, SDWAN, Segment Routing, the Cloud and an exponential increase in bandwidth that have all happened over the past 10 years. Continue reading

The Network 3.0

During the past 3 decades, we have seen a monumental growth in networking technology. From RFC-1163, which describes the beginnings of BGP in 1989 to the cloud and software defined networks of today, our voracious appetite for bandwidth and services have begun to outpace the networking industry’s ability to deliver. Continue reading

The Future of SDWAN – Gen 2 is Here

SDWAN is the hottest topic in networking today. On the one hand, analyst reports state that this industry is in its infancy with less than 5% adoption through 2017. On the other hand, the same analysts project over 50% customer adoption in the next 36 months. Why has adoption been modest to-date, and why is 10X acceleration expected now? The answer lies in understanding the differences between the first generation of SD-WAN (Gen1) and the second generation of SD-WAN (Gen2). Continue reading

Configuration of Office 365 with SD-WAN Policy versus Traditional Router

One of the best aspects of working with application-intelligent SDWAN solutions is the ease of configuration for common SaaS solutions such as Office 365. When I compare SDWAN with the traditional router or firewall approach, I begin to see how antiquated products in the WAN space has been, particularly around today’s diverse application deployment models.

Should SD-WAN Architectures use POPs?

Multiple flavors of SD-WAN are available on the market today. One area of differentiation amongst them is whether or not there is a vendor-hosted traffic handling component in the architecture. In cases where there is no vendor hosting of traffic handling SD-WAN components, devices owned by the business, or, the existing network, are expected to handle all traffic. In cases where there is a vendor providing hosting of some traffic handling components – such as in a cloud access point of presence (POP) – devices owned by the vendor are responsible for handling some traffic. While on the surface this seems to be an unimportant detail, there are several subtleties that must be considered. Knowing which architecture an SD-WAN solution requires can mean quite a bit when it comes to not only realizing the full benefit of your SD-WAN solution, but also the business implications.

Is WAN Optimization Dead?

As an ever present staple of technology in the inventory of any major enterprise, WAN optimizers have begun to lose their luster. While there are still probably thousands in widespread use throughout the world, evolution has conspired to put them on the endangered species list. Do you remember thicknet, thinnet, or token ring? Yup! That kind of endangered! Continue reading

Reducing Branch Office Hardware, Complexity, and Cost

The typical branch office consists of a mix of routers, WAN optimizers, switches, firewalls, wireless, and servers. That’s a pretty considerable investment just in hardware to bring up a moderately sized office. When you add in the costs and labor associated with procurement, installation, and configuration it is easy to see how the bill can equal tens, if not hundreds of thousands of dollars per location.
