Subscription-based options just keep growing, as music, movies and TV, along with your business-critical SaaS apps, are all available now with various monthly payment methods. IT continues to move in this direction too, with network subscription packages the latest trend. Unlike software applications, networking still requires physical parts. But the idea of SDN and a…Continue reading

Just last summer, we published a post that discussed the differences between SD-WAN and WAN optimization. At the time, many people were simplifying the discussion and wondering if SD-WAN could replace aging WAN optimization solutions. When you break down the purposes of each technology, the two look more like a dynamic duo than a replacement…Continue reading

SD-WAN was originally designed to be the successor technology to MPLS networks, but it doesn’t appear to have worked out that way. Research from Nemertes has shown that nearly 80% of companies with a pre-existing MPLS deployment retain the technology after SD-WAN adoption. Clearly there is some synergy between SD-WAN and MPLS. How does an…Continue reading

Software-defined architecture is the next big thing for networks, allowing companies to shift away from costly, inflexible hardware to more agile and adaptable solutions. Consider software-defined wide area networks (SD-WAN), which some experts see as the natural replacement of multi-protocol label-switching (MPLS) solutions currently in use. There’s some justification for this position, since SD-WAN offers…Continue reading

On the road toward software-defined everything, WAN virtualization could play an important part. SDN is useful for a lot of data center networking tasks, like switching. But SDN across existing IP networks doesn’t necessarily bring a lot of value, and many businesses wouldn’t be able to afford to invest in entirely new software-defined networks. SD-WAN,…Continue reading
