Advantages of Chassis based Network Switches
There are a number of advantages of deploying Chassis based Network Switches in the Data Center/ Core-Distribution layers in enterprises. Chassis Network Switches are fault-tolerant, expandable and offer higher performance, among others. Let us look at what are chassis network switches, some of their advantages and limitations, in this article. What is a Chassis... »
VxLAN – Think beyond VLAN for the Cloud!
We are familiar with VLAN (Virtual LAN) which segments a Layer-2 Network into subnetworks and hence limits the broadcast domain. There is a new (upcoming) IETF draft standard called VxLAN that seeks to replace VLAN in Cloud’s, Data Centers and other such large networks. Let us look at why a new standard might be... »
Fanless Network Switches – Would you need them?
We all know that Network Switches are a bit noisy. This noise mainly comes from the multiple fans that operate from within the network switch, in order to cool the various components of the switch from within. But, there are certain situations when we might prefer having a fanless (and hence silent) network switches.... »
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... »
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... »
A Simple Introduction to DNS & DDNS and Why your organization might need them
DNS stands for Domain Name System. A Simple function of the DNS server is to convert a Domain name into IP address & IP address into a Domain name. DDNS stands for Dynamic Domain Name System and it is required to provide a permanent (and easily remember-able) Domain name for remote access when you... »
What is a Public IP Address & Do you need one?
In this article, let us see what is Public IP address, difference between static public IP address and dynamically assigned public IP address, the difference between public IP address and private IP address, applications of public IP address and how you can manage without a public IP address for those applications. »
Why are Subnets required & Subnet vs VLAN
The first thing that network administrators learn is the concept of IP address and creating IP Subnets (short form for sub-networks). But why are Subnets required at all? Especially, when VLAN can do almost the same thing! That's what we are going to discuss, in this article. »
Intelligent Building Management Systems over IP Networks
IP Networks are exciting because convergence (over IP) is happening not just for voice, video and data. Even the IBMS (Intelligent Building Management Systems) are slowly converging over the IP Networks. In this article, we will see a short introduction to IBMS over IP Networks and some of its applications. »
An introduction to Layer-3 Network Switches
Do you need Layer-3 Switches in your network? Possibilities are, that you might already be having some of them... In this article, we will look at what Layer-3 switches are, and some advantages of using Layer-3 network switches. »
