MPLS And VPLS Networks Basics

If you have been checking out Internet service providers, you probably should have come across the term MPLS and VPLS networks. MPLS stands for multiprotocol label switching while VPLS, on the other hand, stands for virtual private local area network service. In a nutshell, if you want something to improve data transfer in your business, then multiprotocol label switching should be your choice. If you want something just to improve access and speed for data transfer in your home, you can opt for virtual private local area network service.

One of the distinctive features of MPLS is the fact that it uses a significantly shorter path labels for data transfer and communication exchange. It rarely has to go through long addresses for networks. This system is actually the framework in which various access technologies are based on. Some of them – like DSL – may even be access technologies that you are familiar with.

There are several advantages to enjoy with MPLS, but most of it would those that only businesses can maximize on. For many businesses, every second counts and every second that they get to save contributes to the increase in their profit margin. Multiprotocol label switching is a time-saver at the very least. It allows owners to bypass routing tables as well as effectively scale back their own networks.

Multiprotocol label switching is also very flexible. Business owners can assign varying traffic levels to their customers. More importantly, it is highly secure as well, being able to operate at different layers.

There are basically three ways you can avail of multiprotocol label switching. The first is to sign up for a Layer 2 point-to-point system. The second alternative would be to go for a Layer 3 Internet Protocol (IP) VPN. » Read more: MPLS And VPLS Networks Basics

Understanding WiMAX Networks And How They Work

October 23rd, 2011 by admin No comments »

WiMAX stands for Worldwide Interoperability for Microwave Access. WiMAX Networks work in a very similar way to WiFi. However, there are often confusions between the two different networks. After all, they both relate to wireless connectivity. The difference between the two is that WiMAX is a long range system.

This system can also work at much greater speeds. The distance they operate over is also much greater. A bigger number of users are able to be connected to the network. This particular type of network makes it possible for people in rural areas to have internet facilities now. Most telephone and cable companies do not operate in remote areas. For these people, the answer is finally here and access to the internet is finally within their reach.

There are 2 parts to a system like this. There is a tower which provides the coverage, the receiver and antenna. The receiver is most commonly a PCMCIA card. Many laptops do however come with built in wireless modems today.

Most tower stations connect via a high bandwidth connection. Line of sight is essential for such a network to operate. They are also able to connect to other towers enabling a wider area of coverage, particularly to very remote areas where internet access is not available through other channels.

Where a non line of sight service is used, a small antenna is attached to your computer. This then in turn connects to the tower. A lower frequency is used. Line of sight is where a permanent fixture by way of a dish is installed. The dish points straight to the tower. » Read more: Understanding WiMAX Networks And How They Work
