Book Review: Navigating Network Complexity

From a small number of hosts that are unreachable to large Internet outages, complexity sneaks up and bites network operators, sometimes at the most unexpected and undesirable times. While many mistakes in networks are manual configuration errors, the events of August 30th 2020, served to remind, that automated processes can sometimes propagate a mistake, fast,…

As Simple as a Static

Dynamic routing changed the networking landscape in ways that can barely be remembered or articulated. Can anyone really imagine a network such as the Internet, with so many different networks (dare I say “internets”), each with their own administrative entity, and administrative policy, with such a rich “mesh” of connectivity/reachability, emerging as it has, with…

Overall Context For Change in Networking

The Network 2025 Article made the following assertion which this article expands on: All of IT has been disrupted by hyperscalers and SaaS. Combined, they have both radically changed customer experience(compared to on-prem software models) and operations excellence(compared to traditional IT models). They have also changed business models. It is in the area of operations excellence that the future…

Network 2025 and Beyond

Introduction As I continue to iterate on, and flesh out, the Internet Innovation Stack which I will use as a way of organizing my technologies of interest, networking is a natural area for me to dive in, as it is the area of technology I know the best. A typical way of articulating the future of networking,…

Hot and Hotables: Wha is hot, what could become hot

The Important Many feel their privacy is under attack. There will be technological, entrepreneurial, and public sector responses At a time when the general-purpose CPU had been declared the winner in seemingly all IT domains, specialized silicon is arising: AI/ML, Storage, networking, and more. IT professionals need to learn the principles of the Cloud era…

Segment Routing: The Journey Back Home

In December 1995, the IETF published RFC 1883, Internet Protocol Version 6. A reasonably modest size document, clearly articulating a focus on expanded addressing, IPv4 header format simplification, improved support for options, flow labeling, authentication & privacy. As the years went on, a good number of people started to see IPv6 as the basis of…

Network Infrastructure: No Rising Tide to Raise All Ships

The Important 50 years on, the Internet, and broadly speaking networking, are a raging success. Network infrastructure growth is often driven by regional, segment, and technology refresh hotspots, leading to inconsistent aggregate growth across the entire market. This dynamic creates management / leadership challenges. There are some broad-based opportunities like SD-WAN and Security. Quick and…

Will Explainable AI Be The Competitive Battlefront?

The Important The explainability of accurate AI/ML algorithms is an inhibitor to usage Entrepreneurs are stepping into address this problem Explainability may become an area of differentiation in AI/ML solutions Quick and free subscription to the leading Cloud, Network, and Security Newsletter, CloudNetSec from bohcay: link Discussion When I started looking at Artificial Intelligence (AI)…
