Distributed Core/Leaf-Spine Network Architecture: An Intro

Distributed Core/Leaf-Spine Network Architecture is catching up with large data center/cloud networks due to its scalability, reliability, and better performance (vs. 3-tier Core-Aggregation-Edge Tree Networks). Maybe it’s time for enterprises and smaller networks to consider implementing Distributed Core/Leaf-Spine Networks, as the architecture enables companies to start small and scale up…

What is a Network Switch?

What is a Network Switch? A network switch is the basic component of a Local Area Network (LAN) that enables one to connect various network devices together and exchange data/information between them. A network switch generally has multiple ports where network devices like computers, printers, servers, etc. could connect using…

Virtual Chassis Technology : Stack/Combine Access Switches across a Campus

Stacking multiple Switches has its advantages but often it is only possible to combine/ stack switches that are physically located within a few meters. A proprietary technology called Virtual Chassis technology offered by a few vendors can combine / stack access switches that are located far away (even a few KM) into a single virtual chassis group with a common management domain and multiple 10GE interlink (backplane) capacity.

An introduction to Quality of Service (QoS) in Wired Networks

Adding more bandwidth is not always the option to solve network bottlenecks. There are other factors you need to consider like latency, jitter, packet loss, congestion, buffer overflow etc that might also affect the network performance. This is where QoS – Quality of Service aware network plays an important part. If at all your network has real time traffic like voice, video etc, configuring and maintaining the right QoS parameters becomes all the more important. Let us look into QoS – Quality of Service for Wired Networks, a little closer in this article.
