MEF und Bob Metcalfe kündigen Carrier Ethernet 2.0 an
Bob Metcalfe, der Erfinder des Ethernet und Advisory Director beim MEF, hat die Einführung des Carrier Ethernet 2.0 (CE 2.0) angekündigt, das sich durch drei leistungsstarke und standardisierte Funktionen auszeichnet: Multiple Classes of Service (Multi-CoS), Interconnect und Manageability, die die Bereitstellung verschiedener Anwendungen über verwaltete und miteinander verbundene Netze weltweit ermöglichen. CE 2.0 ist eine weiterentwickelte Generation der standardis
Carrier Ethernet CE2, la version ultime

Carrier Ethernet CE2, la version ultime
Depuis 1973, le réseau Ethernet n’a cessé d’évoluer pour supporter diYérents câblages et des vitesses plus élevées. La version Wi-Fi et celle destinée aux opérateurs, les produits "Carrier Ethernet", sont en révolution permanente.
L’inventeur en 1973 d’Ethernet, Bob Metcalfe, l’ex-PDG de 3Comet actuellement professeur d’université à Standford, n’a pasmanqué le lancement de la toute dernière mouture d’Ethernet destinée aux communications d’opérateurs. Il préci- sait lors de cet événement, à Net Events, fin février : «CRien qu’en 2011, selon le cabinet d’études IDC, plus de 1,2 milliard de ports Ether- net ont été vendus dont 400 millions de prises fixes et 800 millions d’émetteurs Wi-Fi.C»La ver- sion pour les opérateurs, lancée il y a dix ans déjà, concurrence l’ATM ou le Frame Relay et s’avère très utilisée pour relier les différents relais de réseaux mobiles. De son côté, Nan Chen, président du Metro Ethernet Forum, parie sur la 4G pour relancer un marché assez attentiste, les opérateurs cherchant déjà à rentabiliser leurs anciennes installa- tions pour la 3G. La dernière version pro- pose la gestion de différentes classes de ser- vices (les multi-COS - Class of Service) et une palette de fonctions d’administration et d’outils d’interconnexion. Ces dernières évo- lutions facilitent la création de contrats de niveau de service (SLA - Service Level Agree- ment) qui permettent aux opérateurs et à leurs clients de mieux surveiller et d’établir différents tarifs en fonctions des SLA et de débits. Dans l’optique de la 4G, le trafic de liaisons des antennes, dit backhaul, devrait être multiplié par dix. Pour atteindre les dé- bits annoncés de 20 Mbits de la 4G, l’en- semble des différents commutateurs Ether- net devrait être synchronisé au millionième de seconde.
Vitesse's Carrier Ethernet Portfolio Aligns with New MEF CE 2.0 Requirements

New Technology Architectures Are CE 2.0 Ready and Being Deployed in the IP Edge; A Served Market Estimated to Exceed $500 Million by 2015
CAMARILLO, Calif., Feb 28, 2012 -- Vitesse Semiconductor Corporation /quotes/zigman/4228524/quotes/nls/vtss VTSS +0.25% , a leading provider of advanced IC solutions for Carrier and Enterprise networks, is a first-adopter of the Metro Ethernet Forum's (MEF) Carrier Ethernet 2.0 (CE 2.0) requirements for mobile backhaul and mobile access equipment, the fastest growing markets in the IP Edge network.
"Vitesse has been a long-time member of the MEF and an evangelist for the proliferation of Ethernet technology in Carrier networks," said Martin Nuss, chief technology officer at Vitesse. "We are very supportive of the CE 2.0 requirements as they establish a market definition for the Carrier Ethernet feature set and create a framework for future value-added services. By incorporating the CE 2.0 requirements into our robust and feature-rich Carrier Ethernet technology architecture, we have established Vitesse as the industry's preferred solution provider for the IP Edge market. We estimate that this market will be a $500 million served market for Vitesse by 2015."

Carrier Ethernet 2 standardisation aims for global connectivity
The Metro Ethernet Forum's Carrier Ethernet 2 will allow carriers to more easily manage and share Ethernet traffic
The Metro Ethernet Forum has updated its Carrier Ethernet specification, hoping to standardise the use of Ethernet for global multicarrier services.
"With Carrier Ethernet 2, we're expanding Quality-of-Service [QoS] well beyond best efforts, and will now allow carriers to interconnect to provide worldwide Ethernet service," said Bob Metcalfe, co-inventor of Ethernet, during a Metro Ethernet Forum (MEF) web conference yesterday.
MEF introduced Carrier Ethernet in 2005 as a set of extensions that describe how data communications carriers should use Ethernet in a consistent manner. The new specification, Carrier Ethernet 2 (CES 2), establishes an additional set of rules. CES 2 provides guidance for setting up multiple Class-of-Service (Multi-CoS) definitions, which will allow carriers to establish more nuanced Service Level Agreements (SLAs). CES 2 provides a richer set of management metrics, and it also sets the stage for multiple service providers to exchange Ethernet traffic in a uniform fashion.

Ethernet inventor introduces Carrier Ethernet 2.0
Ethernet inventor introduces Carrier Ethernet 2.0
Bob Metcalfe, MEF advisory director and the inventor of Ethernet has launched the MEF's new Carrier Ethernet 2.0 specification.
Carrier Ethernet 2.0 (CE 2.0), announced overnight by the MEF (Metro Ethernet Forum) adds several features to its predecessor.
CE 2.0 provides for eight services rather than the three in CE 1.0, multiple classes of service, plus new implementation agreements and management specifications.
"Just as the web browser revolutionised the efficiency and usability of the Internet, a new Ethernet will revolutionise the efficiency and usability of Ethernet Service delivery," said Bob Metcalfe, MEF advisory director, the inventor of Ethernet, and professor of innovation at the University of Texas. "We would encourage everyone to join us here at MEF in changing the world again, with a new generation of Ethernet – Carrier Ethernet 2.0."
