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

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.

Net Events: Carrier Ethernet 2.0 и SDN са бъдещето на мрежовите платформи

NetEvents  е  едно  от  събитията  през  го- дината,  които  дават  ценна  и  интересна информация под формата на презентации и дебати за най-новите тенденции в мре- жовия  свят.  В  последните  няколко  изда- ния на конференцията силен акцент падна върху  облачните  технологии.  Без  да  из- местват поглед от “нашумелите” облаци, поредното  EMEA  издание  на  NetEvents  в Германия обърна сериозно внимание на две нови технологии - Carrier Ethernet 2.0 (СЕ 2.0)  и  SDN  (Software  Defined  Networking), които ще дадат подобрени възможности в използването и управлението на мрежо- вите  ресурси  и  услуги.

боб Меткалф обяви Carrier ethernet 2.0

Боб  Меткалф,  създател  на  техноло- гията  Ethernet  и  съветник  в  MEF  (Metro Ethernet  Forum),  обяви  второто  поколе- ние на Carrier Ethernet. То се отличава с 3 нови  стандартизирани  характеристики: поддръжка на работа с множество класо- ве услуги (Multiple Classes of Service - Multi- CoS),  взаимна  свързаност  (Interconnect)  и управляемост,  позволяващи  доставката на  диференцирани  приложения  върху  вза- имосвързани  мрежи  по  света.  Всички  те се  доставят  чрез  напълно  интегрирани свойства  на  услугите  (Service  Attributes), споразумения за реализация (Implementation Agreements) и спецификации на управлени- ето  (Management  Specifications).

CHATSWORTH, Calif., Mar 22, 2012-- MRV Communications™, Inc. (otc qb:MRVC) (“MRV” or the “Company”), a leading provider of optical communications network infrastructure equipment and integration and managed services, today announced it is fully compliant with the Metro Ethernet Forum (MEF) Carrier Ethernet 2.0 (CE 2.0) initiative that was announced last month. MRV is among the first to fully comply with the specifications that will enable service providers to transform their metro networks for a wide range of next-generation services such as mobile backhaul to support the growing 4G and LTE networks. MRV’s OptiSwitch®, an award winning family of compact Intelligent Ethernet Demarcation and Carrier Ethernet Aggregation platforms, exceeds the Multiple Class-of-Service (Multi-CoS), network interconnect, and service OAM capabilities set forth by the MEF in the CE 2.0 initiative.

The OptiSwitch portfolio uses an integrated configuration and management system to make deployment and monitoring of CE 2.0 services simple and efficient. By utilizing the OptiSwitch operating system, a unified platform that runs throughout the portfolio, the solution is able to create the additional CE 2.0 service types, defined for E-Line, E-LAN, E-Tree and E-Access. Key features of the platform not only include Multi-CoS, but Hierarchical Quality of Service (H-QoS) for dynamic bandwidth management and complex traffic switching for global Ethernet Network-to-Network services. These are a required to support the applications driving CE 2.0 on packet, circuit and cable networks. MRV’s award-winning Pro-Vision® service provisioning and network management system further enriches the OptiSwitch CE 2.0 solution by enabling service creation with zero-touch mass deployment with rapid service turn-up. Pro-Vision includes a web-based customer portal that enables the monitoring of real-time service performance and Service Level Agreement (SLA) verification based on the customer’s view.

March 21st 2012, Los Angeles: The MEF (Metro Ethernet Forum) has launched an online study guide to support their Carrier Ethernet Certified Professional (MEF-CECP) program. With 191 MEF-CECPs already registered in 27 countries since the program’s launch last year, the response has been extremely positive. However, the demand for skilled professional Carrier Ethernet expertise is unabated, and this study guide is designed to help bridge the gap. It is available now in universal browser format and as part of the mobile iPad app ‘MEF on the Go’ both available at http://metroethernetforum.org/CarrierEthernetStudyGuide

“We set the bar high, and the quality of applicants has been excellent” says MEF President Nan Chen. “The examination tests them on a vast body of knowledge generated by the MEF over ten years – in addition to materials from the IEEE and other bodies – and we want candidates to spend less time searching the database and more time learning. This guide does exactly that – setting out the essentials in a clear, easy to navigate format with direct links to further study materials.”

The guide already amounts to over 180 HTML pages of concise information, and is being continuously updated and expanded. Those registering to access the free guide can also opt to receive notification of updates via Twitter (@MEFCert). The Study Guide also includes a comprehensive gallery of diagrams used by the MEF, a glossary of terms, and a consolidated list of links to all reference documents.

To qualify as an MEF-CECP, candidates must pass an 80 question multiple choice examination covering the relevant aspects of Carrier Ethernet.  The exam can be taken online at the candidate’s convenience – regulated by web based proctoring technology to ensure the security and integrity of the examination – or taken in an MEF approved test facility. Individuals also have the option of taking class training from an MEF Accredited Training Partners (MEF-ATP). Whether self-taught or professionally trained, every candidate will benefit from the concise and accessible compendium provided by the Study Guide.

“The latest data on Carrier Ethernet 2.0 is already available on the guide”, adds Nan Chen.  “After our February launch of Carrier Ethernet 2.0, the demand for supporting information from MEF has been huge and we see this as being an important vehicle in meeting that need”.
