Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; Why Intent?Why focus on intent? Because you already do. Intent is the inspiration behind innovation; it is the why that drives everything we do. This is the genesis behind intent-based networking: to align the entire system’s behavior to the original motivation and goal of the design, to improve operational efficiency, and to achieve excellence within the network. Intent-based networking spurs evolution from a network that needs constant operational attention with manual human intervention at every update and change, to one that intuitively knows what needs to be done and ...

Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; Organizations are using continuous network verification to move from reactive to proactive operations The network is complex. Anyone operating in today’s distributed multi-vendor network, full of virtual overlays, containers, SDN, and cloud migrations, knows this. Under the weight of all this complexity, it is easy to wonder if excellence is even possible. And what exactly does excellence mean in this context? How do we achieve this lofty goal? As a business executive and leader, I see excellence as the ability to bring out the best in our team in ... Read More

Feed: Blog – Veriflow. Author: Brighten Godfrey; Organizations are using continuous network verification to move from reactive to proactive operations In a previous post I discussed network verification, a new area of technology that applies what is known as formal verification – mathematical analysis of a complex system to determine rigorously if it meets the end-to-end goal – to network infrastructure. But what is network verification good for and how is it different from today’s common practice? Nearly every organization monitors its network, typically by sampling ongoing flows, events, or logs. Isn’t that enough to catch problems as the organization ... Read More

Feed: Blog – Veriflow. Author: Giri Subramanian, Veriflow; Software Engineer; In order to serve the growing infrastructural needs of any company, networks today are much bigger and vastly more complex than they have ever been. Hybrid networks including the cloud (Amazon Web Services, Azure etc.), network virtualization technologies, software-defined networks, mobile devices, Internet of Things and similar technologies are gaining wider acceptance in the community, adding further complexity to traditional physical topologies. Organizations not only have to worry about managing their existing network, but also about other factors like how resilient their network is to failure, how vulnerable their network ... Read More

Feed: Blog – Veriflow. Author: Mike Kay, Vice President, Business Development; It goes without saying that we live in a connected world. All our activities, from our communications, socialization, travel, and collaboration, have been transformed by new technologies. Not only does this “connectedness” permeate our private lives, but it is even more prevalent in the workplace. Organizations today run their business on a myriad of complex interconnected systems. Most of these systems are manufactured by an array of vendors – each with their particular integration and operational nuances. To complicate matters even more, with the advent of cloud computing many companies ... Read More

Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; As the original pioneers of intent verification, we at Veriflow recognized the value this technology could provide to our customers years ago. In 2011, our founders published the original research paper applying formal verification methodology to assure network-wide intent in an operational network. This paper and subsequent research not only gained widespread accolades and awards in the academic community but also served as the foundation for our patented, award-winning Continuous Network Verification technology today, which we were the first to announce to the market in April 2016.

Feed: Blog – Veriflow. Author: James F. Brear, President & CEO; As organizations continually look to change and evolve their networks, they will continue to introduce more complexity into their environments. With this in mind, we see a few trends remaining and new ones emerging in 2018 as teams look to provide continual business assurance. Take a look below for these trends and check out our infographic, Network Complexity and Change – Breaking the Cycle in 2018. 1. Catastrophic Network Failures Due to change induced incidents will Increase as Network Complexity Increases As organizations strive to deliver increasingly advanced technology ... Read More

Feed: Blog – Veriflow. Author: Brighten Godfrey; A new kind of automation uses math to help ensure business goals continuously match reality Across all sorts of networks today – in enterprises large and small, service providers, government agencies, and beyond – there is a transformation towards a software-driven architecture. Where procedures were once manual, they are becoming more automated, driven perhaps foremost by the need for agility, while maintaining availability and protection. That transformation is coming in a broad arc, not a single drop-in solution, and the industry is still figuring it all out; you’ll see me write more about ... Read More

Feed: Blog – Veriflow. Author: Brighten Godfrey; Whether in an enterprise, a service provider, or a government agency, the network has a challenging mission. It has to provide the organization with an agile platform to adapt to changing business needs, from delivering content to rolling out new services to leveraging cloud computing. And it has to provide a dependable platform, free from outages and vulnerabilities. If the network falls short of those goals, then it can directly interfere with the organization’s ability to quickly take advantage of new market opportunities, or can lead to costly security incidents. But achieving a ... Read More

Feed: Blog – Veriflow. Author: Ahmed Khurshid, Co-Founder & Principal Engineer; Changes in network configuration are inevitable to serve business requirements and growth, to perform hardware-software maintenance, and to address security and performance issues. To reduce the risk of unintended effects wrought by network changes, organizations dealing with sensitive data go through rigorous change auditing processes where the proposed changes are evaluated by a team of network engineers. This rigorous change-vetting process is needed to ensure service continuity and to prevent outages and breaches. In some cases, simulated network environments are built to test proposed config changes. However, simulated networks ... Read More
