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.

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.

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.

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
