WAN LEASED LINE

Communication system is one of the most important things of our life. Without this we can’t take the advantage of modern science. At present the communication system is so fast and quick that sometimes it seems to be magic. Internet is a very important form of communication system. Human civilization is very much dependent on it. Our offices, schools, collages, Hospitals, and other institutes are using internet as their main communication system. So the importance and impact of internet in our daily life is undeniable. Leased line is a service which provides internet with a monthly fixed rate. It is also known as symmetric telecommunications. Leased line has also different names such as “private circuit” or “data line”. In leased line there is no use of telephone number and each side of the line is permanently connected. At present there is a big demand of leased line in the market. Every business man wants to connect his geographically distant offices and to do this leased line is the best choice. The important characteristic of leased line is it is not like dial-up connections. Dial-up connections are not always activated but leased line is active 24/7.
There are many providers of leased line in the market. But all of them are not suitable. To fulfill your demand you have to choose very wisely. This task can be difficult because you can find that different providers have different prices for the same service. The main reason of this confusion is network coverage. The price of the service depends on distance between you and the ISP core network.ISP means internet service provider. So to find the best line for your use is very difficult. But you can solve this problem easily. There is a UK based website called Leased-line-comparison which main target is to compare all major ISP across the UK. This service is totally free. You can use their service to find out who is the best provider for you. To use their tools you have to send them your requirements and your post code. Anyone can ask the question that why we should choose them. Well in the answer they are saying that they have access to the pricing tools, network diagrams and POP locations of the UK’s main internet service providers and therefore have the inside knowledge to make sure you receive the best performance and best service at the best price.
There are many different demands and services in leased line internet such as WAN, POINT 2 POINT, Telephony etc. Many people have different demands so they divide their services in different categories. Not all of them are suitable for you. Now we will discuss about WAN.
WAN means wide area network. A telecommunication network which links metropolitan, regional or national boundaries using private or public network transports can be called a WAN. WAN is used to relay data among employees, clients, buyers and suppliers from various geographical locations. There are different forms of WAN such as PAN ( personal area network ), LAN ( local area network ) or CAN ( campus area network ). WAN can be also called a 2+ site connectivity, VPN, MPLS or VPLS. IF you need to connect two or more offices or between offices and data centers then a WAN is the best choice. IF you take a WAN connection then you can choose between the following at each location: Fibre Leased Lines, EFM, FTTC, ADSL, SDSL, 3G or LAN Extensions/P2P. The main advantage of this system is whatever connection from above you chooses they will all connect into a shared core so there is only one network to take care of. Now I will discuss some terms which are related to WAN. The terms are EFM, MPLS, VPLS and POINT 2 POINT. EFM means “Ethernet First Mile”. IT is a copper based internet service and it is in the between of FTTC (fiber-to-the-curb/cabinet) and fiber leased line. By MPLS I mean Multiprotocol Label Switching. MPLS is a high performance mechanism in telecommunication networks. VPLS means Virtual Private LAN Service. BY using VPLS we can provide Ethernet-based multipoint to multipoint communication over IP or MPLS networks. POINT 2 POINT is also known as P2P. IT is a data link protocol. We can use it to establish a direct connection between two networking nodes. So if you are interested to take leased line for your business or home, you must what kind of service you are getting otherwise all the money you invest will be a big loses. Leased-line-comparison can a better solution of your “choosing provider” problem. So you should try them because the service is free and reliable.
