IDG Contributor Network: Why the IETF will be key for standardizing 5G

Most people in the mobile industry are aware that the Third-Generation Partnership Project (3GPP)—and Global System for Mobile communication (GSM) before it—has traditionally been the lead standards organization in specifying mobile network functionality. 3GPP logically partitions the mobile network architecture into Radio Access Network (RAN), and Core Network (CN) components.+ Also on Network World: What we talk about when we talk about 5G wireless + 3GPP will continue to be important in 5G, especially for the RAN-related functionality such as the OFDM and massive MIMO specifications for the radio interfaces. However, knowledgeable observers will also be aware of the fact that a significant number of key 5G protocols will be specified in the Internet Engineering Task Force (IETF). Actually, this is just a continuation and acceleration of trends started way back in 3G.To read this article in full or to leave a comment, please click here

IDG Contributor Network: Has IT become too complex to manage?

In the late 1990s, I was responsible for technical operations for a large healthcare organization. We supported more than 5,000 users across 50 locations and supported three distinct lines of business. We were a very progressive organization at the leading edge of technology innovation in healthcare. It was not a simple operation. Well, at least not for 1997. When I compare that environment to what IT leaders face today, however, a shudder of relief washes over me. There is no point in whitewashing this: Managing the function of IT in my day was child’s play compared to the incredible diversity of challenges facing the modern IT leader. Is it so complex, in fact, that it cannot truly be managed?To read this article in full or to leave a comment, please click here

34 – Q-in-VNI and EFP for Hosting Providers

Dear Network and DCI Experts !

While this post is a little bit out of the DCI focus, and assuming many of you already know Q-in-Q, the question is, are you yet familiar with Q-in-VNI? For those who are not, I think this topic is a good opportunity to bring Q-in-VNI deployment with VXLAN EVPN for intra- and inter-VXLAN-based Fabrics and understand its added value and how one or multiple Client VLANs from the double encapsulation can be selected for further actions.

Although it’s not an unavoidable rule per-se, some readers already using Dot1Q tunneling may not necessarily fit into the following use-case. Nonetheless, I think it’s safe to say that most of Q-in-Q deployment have been used by Hosting Provider for co-location requirements for multiple Clients, hence, the choice of the Hosting Provider use-case elaborated in this article.

For many years now, Hosting Services have physically sheltered thousands of independent clients’ infrastructures within the Provider’s Data Centers. The Hosting Service Provider is responsible for supporting each and every Client’s data network in its shared network infrastructure. This must be achieved without changing any Tenant’s Layer 2 or Layer 3 parameter, and must also be done as quickly as possible. For many years, the co-location Continue reading

No, it’s Matt Novak who is a fucking idiot

I keep seeing this Gizmodo piece entitled “Snowden is a fucking idiot”. I understand the appeal of the piece. The hero worship of Edward Snowden is getting old. But the piece itself is garbage.

The author, Matt Novak, is of the new wave of hard-core leftists intolerant of those who disagree with them. His position is that everyone is an idiot who doesn’t agree with his views: Libertarians, Republicans, moderate voters who chose Trump, and even fellow left-wingers that aren’t as hard-core.

If you carefully read his piece, you’ll see that Novak doesn’t actually prove Snowden is wrong. Novak doesn’t show how Snowden disagrees with facts, but only how Snowden disagrees with the left-wing view of the world. It’s only through deduction that we come to the conclusion: those who aren’t left-wing are idiots, Snowden is not left-wing, therefore Snowden is an idiot.

The question under debate in the piece is:
technology is more important than policy as a way to protect our liberties
In other words, if you don’t want the government spying on you, then focus on using encryption (use Signal) rather than trying to change the laws so they can’t spy on you.

Python Basics – Part 1

Let’s start with Python basics, with the help of program .Theory part in posts is just enough to understand the program.

Python Data Type:

  • Numbers
  • Strings
  • List
  • Tuple
  • Dictionary
  1. Numbers :  
    1.  Int                  1 ,10,-145, 22
    2. Float               1.1,0.9,-29.9
    3. Complex        1.4j, 4e+6j
  1. Strings

Way to remember how slices work in string  is to think of the indices as pointing between characters, with the left edge of the first character numbered 0. Then the right edge of the last character of a string of n characters has index n, for example:

“Crazyouters ”  represented in indices form

0 1 2 3 4 5 6 7 8 9 10 11
C r a z y r o u t e r s
-11 -10 -9 -8 -7 -6 -5 -4 -3 -2 -1 0

Program Code : Str.py

str.PNG

Output

str_out

 

There are special operators in strings

Program Code : str1.py

str1

Output

str1out

 

3. List

The list is a most versatile datatype available in Python which can be written as a list of comma-separated values (items) between square brackets. Important Continue reading

Trump Tower changed to Dump Tower on Google Maps

The world became a slightly better place when Fidel Castro died. Unlike President Obama who said, “History will record and judge the enormous impact of this singular figure on the people and world around him,” President-elect Donald Trump bluntly called Catro a “brutal dictator” whose “legacy is one of firing squads, theft, unimaginable suffering, poverty and the denial of fundamental human rights.”Some unknown person with an internet connection also attempted to be blunt, expressing his or her opinion of Donald Trump via Google Maps; the President-elect’s transition headquarters was renamed to the Dump Tower on Google Maps.To read this article in full or to leave a comment, please click here

Python – Must for Network Engineer

Automation is need of Time.We as network engineers have to go with automation to simplify major chunk of the work done by us.We can not escape from automation.I will be having series of Python posts starting from basics.I  will try to put all  learning  in post in most easiest way.

Let’s start with Basics.What is Python ? As per Wiki ,Python is a widely used high-level, general-purpose, interpreted, dynamic programming language.

In layman terms , it’s one of the coding  language much simpler, easy to understand and most importantly reduces number of code lines in C++ to fewer lines.

It was created by Guido van Rossum during 1985-1990.

Installation:

Note:We will be doing coding in Python 3.

Windows:  can be installed from Site :http://www.python.org

Linux: run below mentioned  command

$ sudo apt-get install python 3.5
