An Introduction To How Metro Ethernet Connects Datacentres
Investing in Metro Ethernet is a wise business decision. 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 enables network communication within a large building, between multiple buildings, or multiple sites. It enhances the Ethernet’s capabilities enabling it to be used over Multiprotocol Label Switching networks, through IP core networks, or over SONET/SDH.
Network topology is used by Metro Ethernet. This topology has individual routers or servers and is connected through fiber optic media or cable. Metro Ethernet is able to use multiple speeds of connection. Datacenters are accessible to companies regardless of speed. This means bandwidth requirements are not fixed. Companies, institutions, and individuals all find that the Metro Ethernet networks are a valuable tool. The basic way to describe Metro Ethernet networks is a business at one end of town plugs into the Metro Ethernet connection while a business on the other side of town also plugs into it. Basically, Metro Ethernet and Ethernet are the same connection. After installation, maintenance is very simple. Individuals and businesses can spend the added time on more important matters. This enables businesses to have access to each other’s datacenters.
Multiprotocol Label Switching is a mechanism high-performance telecommunication networks, such as Metro Ethernet, use to direct and carry data. MPLS labels data then transfers it from one network node to another. It makes it simple to create these links between networks. Data sent through an Ethernet connection is sent to all network nodes, but the destination node is the only one to respond. This is why many companies employ the use of a Virtual Private Network. 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 a small tunnel within a big tunnel. The small one is used to transfer and access data and the large one is the internet connection. The VPN encrypts data then sends it to the other computer. No other computer, besides the intended one, can decode this information.
Many companies, institutions, and individuals are using this technology and the numbers are increasing every day. The language is complicated, but the way it works is simple. The word metro is a derivative of metropolitan. The internet connection is the Ethernet. Doctor’s offices on one side of town are able to access datacenters of a hospital on the other side using Metro Ethernet. The service provider installs a UNI (User-Network Interface) which provides basic Ethernet internet access. The Metro Ethernet uses this interface. The service connection for the customer is made at the UNI. The path between UNIs is created through an EVC (Ethernet Virtual Connection). A cost effective solution for offices that wish to connect multiple locations within a small geographical location is Metro Ethernet Services.
