Metro Ethernet Explained In Simple Terms For The Novice

By Lincoln Vinson


There are different types of computer networks. Computers use networks as platforms through which they connect to each other. Computers and other devices are able to communicate and share resources through the network. Computer network scale is the most common categorization used. Wide Area Networks or WANs, Local Area Networks which are also known as LANs and Metropolitan Area Networks or MANs are some examples of computer networks. A datacentre interconnect is created by applying Carrier Ethernet technology in the development of MANs.

There are Metro Ethernets which have been deployed in many of the world's cities. The Hong Kong Metro Ethernet is an example of one that serves millions of users in that city. There are some that are privately owned ventures while others are public private projects. There are many economic benefits of having such a network for both clients and businesses. It deals with the cost and inconveniences of having each business install its own network. The Metro Ethernet connects both individual as well as corporate clients to a MAN. The use of Carrier Ethernet technology presents several advantages for such large scale networks for several reasons. Compared to other interfaces that can be deployed to provide similar capacities, it is significantly cheaper. Those using the technology will have access to higher bandwidth capacities. Ethernet is also more commonly used by both corporate and domestic customers and this makes linking them to the networks much easier. Providers and clients stand to reap major benefits from the use of Ethernet in MANs as has been so far demonstrated.

Multiprotocol Label Switching also known as MPLS pseudowires can be incorporated in Metro Ethernet set up in an effort to achieve higher speeds on network traffic. MPLS facilitates division of data packets and has them follow specific paths. Time is saved for the router since each packet is labeled. Not only does MPLS save time and thus facilitate higher speeds, it also makes network management easier. Service providers therefore find it easier to monitor, manage and deliver better quality services to their clients.

There are a number of benefits that Metro Ethernets have over wireless connections or DSL. Clients have access to more reliable and secure internet connection since they are connected directly on a dedicated line. The static IP address allocated to clients will also make it possible to undertake web hosting or email hosting. Unlike shared connections, Metro Ethernets will deliver full speeds. This kind of network is especially suited for those who need reliability and its other benefits. Processes that require high capacity such as security surveillance streaming, audio and video conferencing, VoIP and FTP applications are also best served by Metro Ethernet networks.

Flexibility and quality should also be considered along with cost when you are sourcing for a Metro Ethernet provider. Compare the various offers by shopping around. Talking to those who have some experience in using Metro Ethernet will also help you in decision making.
