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. »

How Stacking Multiple Network Switches helps to build a more resilient LAN

How Stacking Multiple Network Switches helps to build a more resilient LAN

There are number of ways to connect the various network switches in a LAN. Stacking a group of network switches to form a single stack unit that can be managed with an individual IP address for all the switches in the stack group would not only make managing a lot of switches easier, it... »

Why not use Link Aggregation to extend your Network?

Why not use Link Aggregation to extend your Network?

Link Aggregation Architecture Diagram: Extending your network using Link Aggregation: Link Aggregation and its advantages: Link Aggregation is a very useful method to combine multiple links to form a single (bigger) link. It can be either two links from two ports of each switch connecting to another switch as shown in the above diagram,... »

What is a Converged IP Network?

What is a Converged IP Network?

A Converged IP Network today refers to the Unified Computer Network (LAN, based on IP) that uses multiple media (Wired, Wireless) to carry a variety of traffic types – Data, Voice, Video etc on a single network without the need for separate networks for each of them. Why Converged IP Networks? The Computer Networks... »

Need, Standards, Salient points and Challenges for 10GE (10 Gigabit Ethernet) adpotion

Gigabit connections, which were earlier used for interconnecting network switches (hence forming the backbone connectivity) have become common to connect the desktop. Is 10 GE (10 Gigabit Ethernet) then taking over any time soon both for interconnectig switches as well as directly connecting the servers? We would explore on whether there is a need... »
