Open Systems integrates security and SD-WAN as a service, including next-gen firewalls and Web gateways. They're the sponsor for today's Heavy Networking podcast. We discuss Open Systems' architecture, how it applies SD-WAN and security policies to traffic, and how Open Systems differentiates itself in this crowded market.

One of my readers sent me this email after reading my Loop Avoidance in VXLAN Networks blog post:
Not much has changed really! It’s still a flood/learn bridged network, at least in parts. We count 2019 and talk a lot about “fabrics” but have 1980’s networks still.
The networking fundamentals haven’t changed in the last 40 years. We still use IP (sometimes with larger addresses and augmentations that make it harder to use and more vulnerable), stream-based transport protocol on top of that, leak addresses up and down the protocol stack, and rely on technology that was designed to run on 500 meters of thick yellow cable.

We love layers and abstraction. After all, building in layers and it’s corollary, abstraction, are the foundation of large-scale system design. The only way to build large-scale systems is to divide and conquer, which means building many different component parts with clear and defined interaction surfaces (most often expressed as APIs) and combining these many different parts into a complete system. But abstraction, layering, and modularization have negative aspects as well as positive ones. For instance, according to the State/Optimization/Surface triad, any time we remove state in order to control complexity, we either add an interaction surface (which adds complexity) or we reduce optimization.
Another impact of abstraction, though, is the side effect of Conway’s Law: “organizations which design systems … are constrained to produce designs which are copies of the communication structures of these organizations.” The structure of the organization that designs a system is ultimately baked into the modularization, abstraction, and API schemes of the system itself.
To take a networking instance, many networks use one kind of module for data centers and another for campuses. The style of network built in each place, where the lines are between these different topological locations in the network, the Continue reading
