The Ethernet is a family of technologies for frame-based computer networking for LANs (local area networks). It was originally developed back in 1972 with the sole purpose of connecting various workstations together with servers and printers. The previous network protocols were specific to the manufacturer.
The traditional LAN-based Ethernet is not very adequate for the specific demands of the carrier class service applications, which include disaster recovery, site-to-site access and mobile backhaul. Today’s users demand much more sophisticated results including:
1. Delivery on an all-inclusive and high performance global service
2. Providers service on the go, in the office or at home
3. Provides connectivity on any device and for any application
4. Provides around the clock data, video or voice-on-demand
Carrier Ethernet Services, which is an enhanced form of the traditional Ethernet for any carrier-class applications and will meet the above highlighted demands.
5 Attributes of Carrier Ethernet
The attributes that differentiate Carrier Ethernet from the traditional Ethernet are:
1) Standardized Services: Offered locally and globally through standardized equipment that will accommodate the existing networks.
2) Scalability: Able to be easily expanded to millions of different subscribers with bandwidth of up to 10 Gbps and more.
3) Reliability: Able to detect and recover from various incidents without impacting the users.
4) Service Management: Ability to centrally manage, diagnose and monitor the network.
5) Quality of Service: The level of service by the carrier is much higher than traditional Ethernet.
Future of the Carrier Ethernet
The Ethernet can be viewed as a service, as well as a networking technology. For the end users, the Ethernet will be viewed as a type of service that is characterized by the five attributes that are described above.
There are three different ways that Carrier Ethernet can be deployed, which include:
1) Ethernet over MPLS (multiprotocol label switching)
2) Ethernet over SDH (synchronous digital hierarchy)
3) “Pure” or conventional Ethernet
The conventional type of Ethernet is the most affordable option, but may be difficult to expand or modify. While Ethernet over SDH is ideal for some regions, the systems are inflexible and may not provide the level of bandwidth that is desired. When you opt for Ethernet over MPLS, this offers superior scalability, as well as bandwidth management; however, it is the most expensive option of the three.
