Why Intent Based Networking (IBN) will Not Save Your Network Anytime Soon ?

 



In every few years, your favorite networking equipment vendor/provider/manufacturer comes to you with something new, suggesting this is the thing you need to solve all your networking problems in order to deliver the " Business Outcomes " that your CxO team is most desperate to achieve since very next second after the " Big Bang ".

Over the years both Networking Industry & Networking OEMs keep coming with new ideas 💡 - Separation of Planes, Centralized life cycle management, BGP as the mothership protocol by fitting every possible thing within that, Separating Policy from - Topology Information & Reachability Information, The magical 3 letters word " SDN ", Policy Based Networking, Application Aware Networking, Automated remediation and last but not least " The Magical Intent Based Networking aka IBN " beside AI Ops and what not.

But, You often forgot to involve qualified business people in defining those modern networking standards and terms, and for whatever reasons neither side ever took interest to step into the other side of the territory to get its basics right or to discuss what's really needed.

So the choice you are left with at the movement is - either you start taking those small steps or wait for IBN to fail (Since SDN and Open Flow have been declared dead already) on delivering those " Business Outcomes " and the cycle keeps on repeating endlessly.

And in case you doubt this, remember:

1. The intent based networking draft doesn't define or talk about " Business Outcomes " or even " Business Intent ".

2. Crazy Network Automation nerds should go and read millions of lines of code that a lady wrote for Apollo 11, which A. Tells you there is fundamentally nothing new in doing that and B. You can only automate better if You truly know the science behind stuff that you are trying to automate but more importantly have been able to frame the problem well enough. But let's circle back on those details and why often network automation fails to deliver true " Business Outcomes " for later post.

3. Most Network Engineers are not on party list when it comes to CxO meetings and most CxOs are either not invited for Network Strategy and Planning Discussions. Beside some exceptions where either party is there to have a cup of good coffee ☕

So you either start living with those ideas and keep chasing the unicorns, or you can take a step back and start thinking how to really get it right...or let's have a chat 😉 since you must remember that living under a rock is a choice...

What Digital Transformation is actually " Not " about



- Technology Adoption
- Technology Lead Innovation
- Customer Experience/CX
- User Experience/UX
- Creating Value / Value Proposition / Value Stream Mapping
- Leveraging Data / Dat Science / AI / ML / Analytics
- Competition or Coopetition
- Digital Strategy
- Business Model
- Process Mgmt. / Process Optimization
- Platforms & Eco-Systems
- Testing Business Ideas Fast & Cheap
- Simplicity

All of those are fallacies :) , didn't get anyone there, won't get you there … all of those are " Empty Words " & " Consequences "

" How to better prepare for interviews "

 


- Every interviewer and every company has patterns & biases, the sooner you find it out, better off you would be.

- There are only two types of interviews, in first case you take everything in control as much as possible from the beginning to the end. To get to that level - invest more time learning about: Mental Models, Human Psychology & Biases, Story Telling, Presentation Skills & Marketing. In second case - the person on other side of the table takes control and take you for a ride.

- Preparing for interviews is a serious business for people serious about their career or at least cracking the interviews.

- While most interviewee care and think more about what they can get from given company and role, flip the question in terms of what you can offer and will bring new on the table - with the later mindset you will perform much better.

- At the end of an interview, make sure you ask questions to better understand your role, work culture, particular expectations that the hiring manager may have, what systems and methods they have in place to measure and rate employee performance but more importantly business performance in terms of business line you will be part of.

1. Learn about different optical fibers types and subtypes - Single Mode vs. Multi-mode, OS vs. OM specifications.

2. Learn about different Optical & Optical to Ethernet SFP types, Distance they cover, Speeds they offer, Connector types they got.

3. Learn the internal architecture of a Router at least at high level if not deep.  

4. Learn at least basics of ASICs and their high level differences among chip makers.

5. Pick early on "Overlay Protocols" such as - GRE, VxLAN & Geneve fundamentals as they seems to be all around in 2021.

6. Pick on fundamentals of "MPLS" - You will need that pretty much everywhere despite being in Enterprise or SP.

7. Learn about fundamental building blocks of Coding - Don't focus on Networking application of it to keep it clean at the beginning.
