Cisco ME Services - Articles. This chapter covers the following topics: L2 Switching BasicsMetro Ethernet Services ConceptsExample of an L2 Metro Ethernet ServiceChallenges with All-Ethernet Metro Networks As discussed in Chapter 1, "Introduction to Data in the Metro," Ethernet services can take either of two forms: a retail service that competes with traditional T1/E1 private-line services, or a wholesale service where a carrier sells a big Ethernet transport pipe to another, smaller service provider.
In either case, multiple customers share the same metro infrastructure and equipment. For TDM deployments, sharing the infrastructure is a nonissue, because the services are limited to selling transport pipes, and each customer is allocated a circuit that isolates its traffic from other customers. When packet multiplexing and switching are applied, such as in the cases of switched EOS, Ethernet Transport, and RPR, things change. Ethernet is a broadcast medium. Ethernet switching includes the following basic concepts: The evolution of Carrier Ethernet | telecoms.com - telecoms indu. The evolution of Carrier Ethernet Carrier Ethernet is no longer the new kid on the block.
Its many virtues, from flexibility and scalability to lower operational costs and greater simplicity and interoperability, are now well understood and widely attractive to carriers and, more importantly, their customers. A number of business trends have emerged that are changing the traditional nature of telecom products and services and driving new demand curves. For example, the maturation of virtualisation and cloud-based applications is driving significant changes in user behaviour and network resource utilisation. The MEF groundwork While initially attractive due to its cost, Carrier Ethernet’s adoption is now primarily driven by the shift in emphasis to top-line revenue growth through the creation and deployment of new Ethernet services with greater velocity, automation and customisation.
Building on the standards The Carrier Ethernet story is today moving on. Metro Ethernet Forum. The ( ), founded in 2001, is a nonprofit international industry consortium , dedicated to worldwide adoption of Carrier Ethernet networks and services. The forum is composed of leading service providers, major incumbent local exchange carriers, network equipment vendors, and other networking companies that share an interest in Metro Ethernet . It had 160 members as of February 2010. The MEF is a combination of a technical and a marketing forum to promote the adoption of Metro Ethernet. This is a key differentiator from other standard bodies such as the Internet Engineering Task Force and the Institute of Electrical and Electronics Engineers (IEEE) .
The forum makes recommendations to existing standards bodies and creates specifications that are not being developed by (or fall within the scope of) other standards bodies.

While Ethernet forms the backbone of many large enterprise networks, it provides the application support, scalability and bandwidth that can adapt to virtually any organization or need. Take advantage of powerful applications Ethernet Services from AT&T Design a network flexible enough to run large, diverse applications across town, the state or even globally. Bandwidth-intensive applications require a robust infrastructure that can deliver data reliably to multiple sites at the same time. MPLS-based Ethernet solutions from AT&T provide multicasting capabilities that can help you get the most out of many applications, including: Distance learningDigital radioTelemedicine / telesurgeryTV station broadcastsBroadcast of streaming videoRetail videoHigh-volume file transfers Protect data and limit network downtime with Ethernet As the core of your network, Ethernet is critical to your business’ daily operations.
Streamline your core capabilities with Business Ethernet Show Me: Internetworking Technology Handbook - Ethernet. Howstuffworks "How Fiber to the Home Works" Stop and think how your Internet usage has evolved during the last few years. If you’re like most people, you’re doing -- and expecting -- a lot more of your Internet like increased interactivity, rich media and uploading and downloading pictures and video. More large files are moving across the cyberspace network these days, and experts expect that trend will only increase.
A January 2008 study by the Discovery Institute estimates new technologies will drive Internet traffic up by 50 times its current rate within the next 10 years. The pressure for better connectivity is one of the main reasons providers and users are looking at fiber-to-the-home broadband connections as a potential solution. Fiber-to-the-home broadband connections, or FTTH broadband connections, refer to fiber optic cable connections for individual residences. What are the advantages and disadvantages to FTTH broadband connections?
