Ethernet Networking For Business Services

(Maggie, Jeffrey M. Wang)



- Ethernet Networking For Business Services

Ethernet, IEEE 802.3, is one of the most widely used standards for computer networking and general data communications. It is widely used in all forms of data networking from connecting to home Wi-Fi hubs to business data networks and telecommunications networking. There are several types of Ethernet networks, such as Fast Ethernet, Gigabit Ethernet, and Switch Ethernet. 

The Ethernet standard has been used for many years, being steadily updated to meet the requirements of growing technology. Data communication speeds have steadily risen and Ethernet, IEEE 802.3 has increased its speeds accordingly. Today, the fiber-based Ethernet networks are capable of delivering speeds up to 100 Gbps.

Although to many, Ethernet is familiar because Ethernet connections are widely used for in the home for wired connections between computers and broadband hubs, but they also provide the essential connectivity for data networking systems used in large enterprises. 

Whether you need point-to-point, point-to-multipoint or multipoint-to-multipoint connectivity, turnkey Ethernet solutions can help you quickly link data centers, clouds and new locations.

- Standards Body for Metro and Carrier Ethernet

Originally, Ethernet is a standard for local-area networks (LAN), that is defined, maintained and extended by IEEE. 

Carrier Ethernet builds on that standard, but is adapted to the needs of metro-area networks (MAN) and wide-area networks (WAN). 

Standards body for Metro and Carrier Ethernet is the Metro Ethernet Forum (MEF). 

Accordingly Ethernet forms the basic technology for connectivity for most local-area networks these days. Versions of it have also been devised for larger enterprises. Carrier Ethernet is one example of how the technology has been adapted for use by network operators or carriers. 


- Major Carrier Ethernet Services

Business Ethernet has been an essential technology for networking since the 1980s, and continues to play a significant role in connecting computers and other devices to each other and to the Internet.  

Whether exchanging large files, emails, working together over video and voice, or accessing data in the cloud, today’s businesses require more bandwidth and more up-time than ever before. 

As a result, many companies are turning to Ethernet service, which provides the ideal bandwidth for common networking needs at affordable rates.

Business Ethernet is a family of networking technologies used for local-area networks (LANs), metropolitan-area networks (MANs), and wide-area networks (WANs), connecting computers, servers, printers and other devices to each other and to the Internet. 

Business Ethernet connections may use coaxial cable, twisted pairs or fiber-optic cables. Business Ethernet services provide a faster and more reliable connection than wireless network connections. 

There are several other major Ethernet Services: Ethernet Network Services, Ethernet Virtual Private Line, Ethernet Dedicated Internet, Business Internet, Ethernet Private Line, and Cell Backhaul.


- Advantages and Disadvantages of Metro Ethernet

Metro Ethernet is a network that provides high-speed connectivity within a metropolitan area or larger geographic area. It's based on Ethernet standards and is commonly used to:

  • Connect subscribers to a larger service network
  • Provide internet access
  • Connect branch campuses and offices to the internet

Metro Ethernet is scalable, secure, and reliable for large enterprises. It's typically delivered by a local or regional provider. 

Metro Ethernet has the following advantages:

  • High-speed connectivity
  • Scalability
  • Security
  • Reliability
  • Uptime of 99.999%

However, Metro Ethernet also has some disadvantages, including:

  • Latency
  • Small upload speeds
  • High packet loss

The maximum throughput for this network is 10gbps. Metro Ethernet services and topologies include:

  • E-Line (Ethernet Line Service)
  • E-LAN (Ethernet LAN Service)
  • E-Tree (Ethernet Tree Service)
