An Explanation Of The Way In Which Metro Ethernet Links Datacentres

By Ernestine Baird


Metro Ethernet is a valuable and vital tool to enhance business or organization operations. It connects company networks and datacenters to others across town. Individuals and businesses are able to connect to the internet, small networks, or to large corporate networks. Small college campuses are able to connect to their mother campus networks.

Carrier Ethernet allows networks, separated by distances, to connect. It can be among different campuses or offices, among buildings on one site, or simply within one large building. Carrier Ethernet increases Ethernet's abilities allowing it to be used over SONET/SDH, Multiprotocol Label Switching networks, or through IP core networks.

Metro Ethernet utilizes network topology. This topology has individual routers or servers and is connected through fiber optic media or cable. Metro Ethernet uses connections of multiple speeds. Datacenters are accessible to companies regardless of speed. It also means there is no fixed bandwidth requirement. Companies, institutions, and individuals all find that the Metro Ethernet networks are a valuable tool. The simplest explanation of the Metro Ethernet networks is a company on one side of town connects to Metro Ethernet and simultaneously one on the other side of town does the same. An Ethernet connection and Metro Ethernet connection are essentially the same. Maintenance is very easy once it is installed. It gives individuals and businesses additional time to concentrate on more important matters. This allows access of datacenters to multiple businesses.

Metro Ethernet, a high-performance telecommunication network, uses a mechanism known as Multiprotocol Label Switching which directs and carries data. MPLS uses labels to transfer this data from one network node to the other. Creating links between networks is simple using MPLS. Data sent through an Ethernet connection is sent to all network nodes, but the destination node is the only one to respond. A Virtual Private Network ensures a company's security. This is a computer network that utilizes public telecommunication, like the internet, and provides individuals and offices secure access to their company's network. VPN is much like one small tunnel inside a larger tunnel. The large one represents the internet connection and the small one is the route the data takes. The VPN encodes data before sending it to the other computer. The intended computer is the only one that can read this data.

The number of companies, institutions, and individuals using this technology is increasing every day. The language is complicated, but the way it works is simple. The word metro is derived from metropolitan. The internet connection is the Ethernet. The emergency room of a hospital, through Metro Ethernet, is able to access the datacenter of a doctor's office across town. A UNI (User-Network Interface) is installed by the service provider for the Ethernet connection. This is the interface that the Metro Ethernet uses. The UNI is where the customer service connection is made. The path between UNIs is created through an EVC (Ethernet Virtual Connection). Metro Ethernet Services may be a more cost effective solution for offices that wish to connect multiple locations within a small geographical location.
