BGP for Service Layer Migration and Perhaps More

The Important Over the next five years (Network 2025), migration will be top of mind for IP Architects and Engineers, as many networks transition to Segment Routing (SR) for MPLS (SR MPLS), Segment Routing for IPv6 (SRv6), IPv6 (without segment routing), and other migration scenarios in between. BGP-based VPNs support numerous forwarding/data planes, enabling the…

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,…

IP Traffic Engineering & the Automation Dividend

If we think of traffic engineering (TE) as the real-time to long-term mechanisms for networks achieving performance objectives & customer SLAs, in the presence of network failures & topology changes, then we might assert there are three forms of TE: Throw huge amounts of bandwidth at it Throw less bandwidth at it and have a light-weight approach…

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…

Blockchain

The Important Blockchain is not a database. Blockchain is a journal. Blockchain is best used to record immutable information Blockchain should not be used for mutable information Blockchain does not provide anonymity1, transaction partners are known Blockchain does provide confidentiality, specifics of records can be hidden Note (1): The traceability of criminal behavior has nuances….

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…

Short time to execute the right thing

Obviously, the world is having a “moment”. When the death of an African American man in the custody of police causes worldwide protests and more, you know a) we live in a global digital world and b) this is the time to act and make change; the emotion is there, the desire is there, the…

Silicon Strikes Back

In a galaxy not too far away, fear spread that Moore’s law was coming to an end. It was getting harder to increase the frequency on a CPU, leakage was increasing even as transistor size was decreasing, and a breakthrough in material science seemed desperately necessary. What was a scared IT industry to do? Go…

COVID-19 demonstrates that AI/ML remains underhyped

When I wrote in October 2019, that AI/ML was underhyped, I was not even thinking of public sector applications. Luckily, Bluedot was. If you still believe AI/ML is overhyped, then I would encourage you to watch the 60 minutes piece from April 26th, 2019 on this very issue, and how really good data, and a…

Oh, pandemics, that’s why we need ubiquitous broadband!

I get it, COVID-19 is now going to become everyone’s pet excuse for funding. Everyone will be lining up at the government trough for their favorite cut of pork. However, I would argue ubiquitous 5G, that we can trust, is a critical national/global priority. Global shutdowns have pushed the conversation way past the historical debates…
