The 12 Basic Truths Of Networking

Overwhelmed by all the change going on in the networking industry? Remember that it's all packets and protocols, along with a good helping of common sense.

Today's computer networks seem incredibly complex. Networking technology allows us to instantly share information, easily perform work outside the office, and access entertainment and social services we never dreamed of 20 years ago. Smartphones are ubiquitous, even in many underdeveloped economies. The software layer is separating from hardware, allowing programmable and automated networks. And networks promise to become even more widespread as additional devices and systems come online to usher in the Internet of Things.

That said, the underlying infrastructure of business networks and the Internet has remained largely unchanged since the first client-server connections. What we can do with the network has changed dramatically and some elements -- such as wireless access -- have grown in importance. But with the exception of IPv6 rolling out slowly but surely, the basic protocols and components of network infrastructure would be familiar to a networking pro who last sent a ping test when Bill Clinton was in office.

Yes, job responsibilities may be shifting as technologies like virtualization take hold, but today the most important protocols on the network are still Ethernet, TCP/IP and BGP. And many of the principles veteran networking professionals learned on their first jobs continue to ring true.

That's illustrated clearly, and entertainingly, by IEEE RFC 1925, which was written almost two decades ago in 1996. The authors outlined 12 tenets of networking technology collected via "extensive study" from the IEEE community. They call them "the fundamental truths underlying all networking." Ponder them and decide if you agree.

Could have shared this article completely on half a page!
Really, do I have to scroll through 13 pages of manutia to read one or two sentences each page?  What a waste of time & resources!

Novice Speak: " This Stuff is easy ......"

"....It is more complicated than you think."

 

Absolutely agree.  I can think of few disciplines that better expose this truth more than the field of networking. 

No matter how much one thinks they understand about networks and networking in general, it doesn't take long to come across a term or concept that is new or at least needs to be reviewed to refresh one's base understanding.

Need a Solution ? Kick The Can.
"...It is easier to move a problem around than it is to solve it."

 

Living this axiom now.  

 

Scenario:  Need more storage.

Solution:  Buy external drives.   

Outcome: Issue kicked down the road -  Not solved just delayed.

The Manual says.....

"...Some things in life can never be fully appreciated nor understood unless experienced firsthand."

 

This is so true, so often I have read about concepts yet nothing sticks better that actually having to do it.

Anything Faster Than Fiber ?

"....No matter how hard you push and no matter what the priority, you can't increase the speed of light."

 

 

Is this a loose reference to fiber ?

Networking Improvements: How much does that cost ?

7. It is always something.

I really like this because it is true.   The corresponding corollary also rings true.   I can't believe how many VP's want this and that but don't want to allocate a serious budget for it.

The old adage, you get what you pay for....

Still holds true.

Re: IEEE
I find IEEE bit confused, may be due to complexity in network protocol building they face with day-2-day agressive demand .

That IEEE Networking Group had a good sense of humor back in 1996!

If you thought consumerization killed UC, think again: 70% of our 488 respondents have or plan to put systems in place. Of those, 34% will roll UC out to 76% or more of their user base. And there’s some good news for UCaaS providers.
