ENSLD Journey – The Intro

I have a 2022 goal of achieving the CCNP Enterprise certification. Late last year, I passed the ENCOR exam and now need to pass one of the concentration exams to achieve the full CCNP certification. Due to my interests, I have decided to go for the design specialization. To achieve this specialization, I need toContinue reading “ENSLD Journey – The Intro”

Challenges and Opportunities – Year Over Year

At the end of 2020, I made a conscious decision that 2021 was going to be different. Now, I should say that things had been going well. I had been happy with my career and home/family life. However, there was something missing. I had never really set solid goals for myself. I would always justContinue reading “Challenges and Opportunities – Year Over Year”

NFD26 – Performance Monitoring w/ NetBeez

The NFD26 series of posts are my commentary from specific presentations held for Networking Field Day 26, a virtual event presented by Tech Field Day. Let’s face it. None of us like getting that call. You know which one I’m talking about. The one that makes you cringe immediately when your brain processes it. TheContinue reading “NFD26 – Performance Monitoring w/ NetBeez”

NFD26 – Scaling Discussion w/ Arista

The NFD26 series of posts are my commentary from specific presentations held for Networking Field Day 26, a virtual event presented by Tech Field Day. Something that really peaked my interest during Arista Network‘s NFD26 presentation was the time they spent discussing scaling caveats and opportunities in modern data centers. There continues to be debates,Continue reading “NFD26 – Scaling Discussion w/ Arista”

NFD26 – Experience First Networking w/ Juniper

The NFD26 series of posts are my commentary from specific presentations held for Networking Field Day 26, a virtual event presented by Tech Field Day. Before getting started, I want to put some high-level definitions on some terms used throughout this post. MistAI: Juniper’s cloud hosted platform that aggregates analytical data from a customer’s JuniperContinue reading “NFD26 – Experience First Networking w/ Juniper”

ENCOR Journey Series – Quality of Service

Bandwidth is infinite and we never need to worry about congestion, slowness, and packet drops, right? Of course, the answer to this is “no”. Networks transport many different kinds of data, and the different types may need to be handled in different ways to provide the best user experience during times of congestion. When IContinue reading “ENCOR Journey Series – Quality of Service”

ENCOR Journey Series – Multicast Operation

In the last post, we covered the background of multicast. What it is, and why it’s leveraged in networks. In this article, we will dig deeper into multicast operation and routing. When we think in terms of unicast, we think about delivering data toward the destination. We have a destination IP address that belongs toContinue reading “ENCOR Journey Series – Multicast Operation”

ENCOR Journey – Multicast Background

Unless otherwise specified, I think it is easy to go into a routing scenario or situation assuming that the traffic flows are unicast. What do I mean by this? Unicast traffic flows are what I will call the “typical” end user type communications in a network. One device needs to talk to another device. TheContinue reading “ENCOR Journey – Multicast Background”

Automation Journey – Python: The Basics

The title of this post really says it all. I want to become a more automation/programmability minded person and to kick off this journey, I decided to start by getting a familiar with Python. As time permits I am going through Al Sweigart’s “Automate the Boring Stuff with Python” book and Udemy course, and planContinue reading “Automation Journey – Python: The Basics”
