The orbiting satellite transmits and receives its information to a location on Earth called the Network Operations Center (NOC). NOC is connected to the Internet so all communications made from the customer location (satellite dish) to the orbiting satellite will flow through the NOC before they reached the Internet and the return traffic from the Internet to the user will follow the same path.
Data over satellite travels at the speed of light and Light speed is 186,300 miles per second. The orbiting satellite is 22,300 miles above earth (This is true for the GEO-based satellite)
The data must travel this distance 4 times:
1. Computer to satellite
2. Satellite to NOC/Internet
3. NOC/Internet to satellite
4. Satellite to computer
This adds a lot of time to the communication. This time is called “Latency or Delay” and it is almost 500 milliseconds. This may not be seen so much, but some applications like financial and real-time gaming don’t like latency.
Who wants to pull a trigger, and wait for half a second for the gun to go off?
But, latency is related to which orbit the Continue reading
The post Tier 1 Carriers Performance Report: May, 2022 appeared first on Noction.
The early October 2021 Facebook outage generated a predictable phenomenon – couch epidemiologists became experts in little-known Bridging the Gap Protocol (BGP), including its Introvert and Extrovert variants. Unfortunately, I also witnessed several unexpected trips to Mount Stupid by people who should have known better.
To set the record straight: everyone’s been there, and the more vocal you tend to be on social media (including mailing lists), the more probable it is that you’ll take a wrong turn and end there. What matters is how gracefully you descend and what you’ve learned on the way back.

How do you balance loyalty to yourself and loyalty to the company you work for?
This might seem like an odd question, but it’s an important component of work/life balance many of us just don’t think about any longer because, as Pete Davis says in Dedicated, we live in a world of infinite browsing. We’re afraid of sticking to one thing because it might reduce our future options. If we dedicate ourselves to something bigger than ourselves, then we might lose control of our direction. In particular, we should not dedicate ourselves to any single company, especially for too long. As a recent (excellent!) blog post over at the ACM says:
The idea that we should control our own destiny, never getting lost in anything larger than ourselves, is ubitiquos like water is to a fish. We don’t question it. We don’t argue. It is just true. We assume there are three people who are going to look after “me:” me, myself, and I.
I get it. Honestly, I do. I’ve been there Continue reading

In this post, we will look at what is CCIE Service Provider v5.0, what comes with it, which technologies we need to learn, what is the difference between CCIE SP v4 and CCIE SP v5, why you should study for CCIE Service Provider v5, when you should study for CCIE SP exam, after which certificate you should aim it for, we will look at all of these questions.
The CCIE Service Provider v5 lab exam is testing skillsets related to the service Provider solutions integration, interoperation, configuration, and troubleshooting in complex networks. CCIE SP v5 is the latest version of the CCIE Service Provider lab exam. When the candidates pass this exam, they get their CCIE number.
This certification syllabus covers most, if not all real-life Service Provider network technologies.
From the technology standpoint, the biggest difference between CCIE SPv4.1 and the CCIE SP v5.0 exam is Network Programmability and Automation Module. It is 20% of the entire exam, thus very important in the CCIE Service Provider exam. You can access Orhan Ergun’s CCIE SP Network Continue reading
Today on the Tech Bytes podcast, sponsored by Palo Alto Networks, we talk about Zero Trust Network Access and how it’s evolving to provide more comprehensive and consistent security.
The post Tech Bytes: The Evolution Of Zero Trust Network Access (Sponsored) appeared first on Packet Pushers.
I see some people have been asking what other people are thinking about Orhan Ergun’s CCIE Enterprise course, thus starting today to share what other people share about us on their blog posts as well. Not just on social media, but with these blog posts, because they are able to share more thoughts about us, I think it is very valuable feedback for everyone.
I would like to start with the website ‘ samovergre.com ‘.
He is our CCIE Enterprise student and you can find his CCIE study plan on this page. He is sharing feedback about our CCIE Enterprise training and other study materials he uses for his CCIE Enterprise study.
One thing that was very important there was that He understand the uniqueness of our CCIE Enterprise Training. It is the design part.
Everyone can teach you how to configure routers or routing protocols, but a design mindset is a completely unique thing and for years, if you are a Network Engineer, probably you have heard about our CCDE training and its success too.
Now, we continue delivering our design knowledge and experience to our CCIE students as well and Continue reading
