For some of us, building a network from the ground up is a huge challenge. Understand, once we have that network built we could have some general network challenges that would happen just due to the way the equipment is designed to operate. In this article, I will demonstrate some of the general challenges that networks face today. Asymmetric Routing Things might seem perfectly happy and healthy in your network, until you realize the traffic is going out on one path and com

Every switch out of box isolate devices in to their own collision domain that means those devices can only see traffics that is sent to and from them as well as some broadcast traffics. But often times as network administrator we want to keep an eye in to the network because we want to be able to see what really is going on the network so we can pipe the output to any monitoring workstation running a tool like Wireshark to analyze the packets. In order to do that cisco allow

No, it isn’t called Unreliable Data Protocol, although many will nickname it that way so they can remember it. UDP is an option at the transport layer that doesn’t provide a connection oriented or session based reliable communication; instead we say it is unreliable and connectionless. In this article I will explore in detail UDP and its operation. The best analogy I like to differentiate UDP and TCP is to consider TCP an actual phone call where you have the initial “hello”

It won’t take you too long being in a technology world to realize there is a concept out there called the OSI Model that people keep referencing again and again and again. This mythical concept that every technology personnel use to categorize layers and functionality is a foundational reality of connectivity. Thus what I would like to do in this article is to walk you through what the OSI Model is all about conceptually, then apply it to real life. If you haven’t seen it b
