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.
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.
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.
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.
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 would also introduce switch level and link level redundancy to your LAN. In this article, we analyze the salient points about stacking multiple switches together and how various vendors have implemented it, in order to get a better idea about stacking multiple network switches and its advantages.
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…
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…
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 for 10 GE ports, 10 GE interconnections, standards and types of pluggable optics for 10 GE as well as salient points along with the limitations of the 10 Gigabit Ethernet, in this article.
This article gives an overview of why manageable switches are required, what features set them apart from unmanaged switches, and why you might want to invest a little more to accommodate managed switches even and especially at the network edge – switches which you use to connect the PC’s.
This article talks about the various ways of extending a Local Area Network (LAN) segment using wired, wireless as well as service provider options.
Did you know that a video conferencing application needs a latency less than 300 ms to give a good quality video images in your IP Network? There are other real time applications that require the network to maintain an optimum performance. Let us explore what parameters of the network performance could be monitored, in this article.
This article gives an introduction to NAT – Network Address Translation, explains why NAT is required, gives an introduction to NAT Traversal (required for certain streams like SIP/H.323) and lists the techniques available for doing the NAT Traversal.
This article explores the options available for high availability in network switches at the device level, operating system software level, Quality of Service and configuration changes, notification level.
This article gives an introduction to DNS and DHCP – what they are and why you need them. There is also a small explanation on what is an IP Address and what is a subnet mask.
