What is business ethernet services?
Carrier Ethernet services for business organization are becoming more & more popular now a days. If you have been hearing about Ethernet service & thinking if it makes any sense for your company, here’s what it’s all about.
Ethernet is the best and the most popular LAN protocol by far. It’s difficult to remember that not that many years ago there were all types of competing network protocols. Now switched Ethernet is almost universal. Something similar is underway with telecom services. We are in the process of swapping over from switched circuit technologies hyped by a century of telephone development to packet switched networks more suited with computing devices. As one might suspect, Ethernet is making it advance to become the universal protocol of metropolitan & long-haul networks. Ethernet emerged at Xerox PARC as a short distance communications technology to interconnect computing equipment. It was planned for use within an office or building. Communication farther than this required concatenation to telecom technologies, such as T-Carrier, SONET & Frame Relay. Over the years, Ethernet has been extended & improved with the introduction of switching to eliminate the problem of collisions & fiber optics to increase network speeds. What has remained the same until recently is that connection to the outside world required conversion to a different set of protocols & back again at the other end. This is the last perimeter of Ethernet networking that is now being labeled by Carrier Ethernet. Business Ethernet Service is best for business organization. What is Carrier Ethernet? It’s the same as Ethernet, but only extended to work over long distances on a telecommunications network. Carrier Ethernet standards been made by the Metro Ethernet Forum (MEF), an industry standards body. By launching MEF compliant Ethernet services, carriers can be assertive that their services will work with readily available customer & provider interface equipment & that network providers will be able to exchange traffic. They do that via Ethernet Network to Network Interface (E-NNI). Two of the most popular Ethernet have services are E-Line or Ethernet Line Service & E-LAN or Ethernet LAN service. E-Line is a point to point dedicated line service that replaces traditional private lines such as T1, DS3 & OC-3. One end of the cable can be connected to an Internet Service Provider to provide you Ethernet Internet service. In computation, E-LAN offers a many to many or meshed connection so that numerous business locations can be tied together on one large Ethernet network. How about bandwidth? There are two physical layer options available. They are Ethernet over Copper (EoC) & Ethernet over Fiber (EoF). Ethernet over Copper is a direct T1 line restoration. It uses the paired twisted pair copper telco wiring that T1 is provisioned over. Multiple pairs are employed to increase line speed. Popular EoC speeds are 2 Mbps, 3 Mbps, 5 Mbps, 10 Mbps 15 Mbps & 20 Mbps. Copper based Ethernet is distance sensitive, so the closer one to the central office, the higher speed one can obtain. It’s common to get 25 Mbps, 50 Mbps, 100 Mbps or higher bandwidths for connections under a mile. Ethernet over Fiber takes up where Ethernet over Copper leaves off. Bandwidths from 10 Mbps to 10 Gbps are easily and readily available, meeting the needs of just about any business. In addition to easy interfacing & options such as E-LAN, a major draw of Carrier Ethernet services is their reduced cost. It’s is common to get twice It’s difficult to remember that not that many years ago the bandwidth for the same money with Ethernet versus other telecom services. Also, that bandwidth is more easily scalable. The carrier equipment design makes it easy & fast to increase & decrease bandwidth as needed, up to the maximum speed of the installed port.
